What matters most to a restaurant? Is it the guests, who pay startling sums of money to be there? Is it the local farmers who grow the ingredients that fill the pantry? Or the cooks who craft dishes worth buying?

No, no and no. Judging from the amount of care expended, there's nothing restaurants value quite so highly as ketchup.

Say a table orders two rounds of onion rings and a single serving of fries. By the end of the meal, those grease-happy diners will likely have burned through half a bottle of ketchup. But that bottle won't reappear in its half-empty state, nor will it be topped off from the giant bladder bag of ketchup that's a fixture on most restaurant kitchen walls. Instead, a server will slowly pour the vestigial ketchup into another under-filled ketchup bottle, creating one full bottle (and one bottle bound for the dish room).

Marrying ketchup is standard practice at every restaurant where ketchup is consumed, which – at least in this country – means every restaurant, period. With the almost imperceptible exception of hoity-toity places that make their own ketchup and serve it in ramekins, American restaurants rely on 10-ounce Heinz ketchup bottles – and expect their servers to keep said bottles looking fresh.

Normally, macarons are like the one above, colorful, light, and full of sweetness. But what if it wasn't?

The world has seen chocolate on chicken and bacon cookies, so why not Ketchup Macarons? It's almost natural -- tomatoes are fruit too, yet they never get the cookie love. Just replace that center above with the spice of ketchup.

David Lebovitz recently whipped up a batch of Pierre Hermé's ketchup macarons, noting the perception in Europe that Americans put ketchup on everything. I can't say I blame them for that assessment (sandwiches, eggs, fries, meat, you name it). But making it into a cookie... That's something I want to taste for myself.

And speaking of unique cookie flavors: What's the most unique cookie flavor you've ever tasted?

When it comes to figuring out who created various condiments, history tends to be amazingly vague. For example, although we know that mustard was developed by the ancient Romans, we have no idea about the identity of the unknown chef who first combined wine vinegar and ground mustard seeds. Similarly, history records that ketchup originally came from China, where it was a form of fish sauce; however, there is no record of the person who made this great leap forward. Similarly, the sands of time have swallowed the name of the great pioneer who first drizzled the magic ingredient on french fries.

So it goes: from relish to chutney, jelly to ice cream, history may occasionally honor a key innovator or entrepreneur, but all too often neglects the silent inventor who toils in obscurity. With that in mind, it seems particularly vital that we honor those few, rare pioneers whose names have not been lost to history. One such man was Alan S. Geisler, who died last week at the age of 78. Geisler, an MIT-trained food technologist, developed the iconic red onion sauce that is a standard condiment on New York City hot dogs. Comprised of vinegar, onion, tomato paste and other ingredients (including corn syrup), Geisler's concoction is better know as Sabrett onion sauce, for the company that markets it.

While hot dog cuisine can be fiercely regional, Sabrett sauce is a vital ingredient for New York dogs. Transplanted New Yorkers (or those who are curious about this distinctive condiment) can order it here or follow this recipe to make it at home. It is best served atop either a dirty water or freshly grilled dog, along with sauerkraut and spicy mustard. Enjoy!

Kids will be kids, right? Well, in the town of Caister-on-Sea, near Great Yarmouth (about three hours from London), police have asked local grocers to help out in preventing kids from being quite so kid-like. Area residents were reporting having ketchup squirted at their cars and, while that's not a criminal act on its own, if the ketchup were to cause damage to the paint, the perpetrators would be liable.

So the police went to the grocery stores and asked them to stop selling ketchup (and eggs) to young people in bulk amounts, in order to prevent this "anti-social behavior." Apparently the action is making a difference, as without easy access to their chosen mischief media, the teens are settling back into their law-abiding behavior.

When I talked to my mom yesterday, she had just finished picking the last of the tomatoes off the plants in the backyard. The weather in Portland has made the seasonal shift from Summer to Fall (unlike here in Philly where it is still gorgeous and warm, with only a hint of autumnal crispness) and so it was time to get any remaining produce out of the garden and transformed into states that store well. She made a huge batch of tomato sauce which got frozen in quart sized ziploc bags.

However, she's still got mountains of tomatoes and is in the market for some additional ways to use them. I think that there might be others of you who are in the same predicament. If so, you could turn some of your bounty into a batch of tomato paste like they did over at the Apartment Farm. If you don't have a food mill, don't let that stop you from making this recipe. You can use a fine mesh sieve and a rubber spatula instead. Another option comes from Nicole at Farm to Philly, who transformed the sea of red covering her outdoor table into two pints of homemade catsup. I'm especially tempted by this recipe, as I hate the fact that most ketchup includes a (not so) healthy does of corn syrup.

I'll skip over the obvious "American Fry" jokes and get right to it. Tara Reid, probably best known to the world for both her role in the American Pie movie franchise as well as her (former) globe-trotting, hard-partying lifestyle, has announced her plans to open a fast food establishment in Los Angeles.

The new restaurant, set to open on March 31st, will be named Ketchup - and though the menu has not been released as yet, Tara herself plans to spend time in the kitchen "making sure everything is done properly."

Though it may seem like a strange move to some, the restaurant business is in her blood. Growing up in New Jersey, Tara's parents owned a bar, and she currently has shares in three other restaurants - Bella, The Shore and Geisha House.

For those of you not familiar with this Portuguese sausage, it's pronounced Ling-GWEES-a. I was waiting tables in a pizza place about 20 years ago and a tourist asked me what this "Linguicka" was.

It's fantastic in sandwiches and on pizza, but you can also make chili with it. One of the best bowls of chili I've ever had was made with linguica instead of beef. It gives the chili a really nice, different flavor, while remaining hearty. I don't know how this place made it, the exact recipe. I'm sure I could call them up right now and say "hey, give me your recipe," but I don't want to do that, even though they probably remember me coming in there.

Utah has a claim to fame other than Mormons and The Osmonds. It's fry sauce. The pinkish concoction has been around for more than 50 years and is the states condiment of choice for French fries.

The stuff is so popular at home and in fast-food spots that there was a fry sauce pin made for the 2002 Olympics. The basic recipe for fry sauce is simple: one part ketchup to two parts mayonnaise. Of course there are numerous variations on the coral-colored condiment. Some restaurants add salt, spices, garlic, relish, horseradish and even pickle juice.

As with many flavors that have captured the public's palate, there's a secret recipe. Gary Roberts, president of Arctic Circle restaurants, which claims to have invented fry sauce in 1948, keeps his fry sauce formula in a safe.

Utah, however, no longer leads the country in fry sauce consumption. Washington and Oregon now consume more of the stuff than the state where it originated. Go figure.

The competitors on Top Chef seem to endlessly complain when they have to work with an ingredient that they didn't make from scratch, repeating ad nauseum that they feel such things - namely, processed foods - are far beneath them. But using commercial ingredients isn't beneath all chefs, not even ones like Jean-Georges Vongerichten and David Bouley. Vongerichten serves his Two-Flavored Stir-Fried Shrimp in a sauce of Hellmann's Mayo and condensed milk. Bouley uses Heinz Ketchup in several sauces, including the one served with his Braised Hawaiian Yellowtail appetizer. Other secret ingredients in chefs' pantries include Gravy Master, Kraft Singles, canned creamed corn and Dr. Pepper.

How are high-end, starred chefs getting away with using ingredients that you could find at a convenience store? The answer is that they don't advertise it the same way that they highlight grass-fed beef and organic tomatoes on their menus.

Last year, the HJ Heniz Company received a score of 91 points out of a possible 100 on the American Consumer Satisfaction Index (ACSI), a ratings system based run by the University of Michigan and independent consulting firms, which tracks American consumer preferences and overall satisfaction. It was the highest rating in the history of the index and there was some small speculation that the company could not sustain that level of performance. But this year, for the seventh consecutive time, Heinz is coming out on top of the ACSI list again. Their score did dip slightly to an 87 out of 100, but a spokesman said "the survey results illustrate once again, that Heinz offers high quality food products to our consumers" - and that the customers are clearly satisfied.

Heinz may have some real competition next year, though. They only narrowly beat out their three closest competitors on the ACSI list - Hershey, Kraft and Mars - each of which scored 86 out of 100.

It seems a little late for a company to suddenly be jumping on the low-carb bandwagon (at least, I haven't previously noticed it in my area), but that's pretty much what Heinz has done with their one-carb Reduced Sugar Ketchup. The ketchup has 75% less sugar than their regular ketchup and 2/3 fewer calories. Since it is being marketed as a healthier alternative to regular ketchup, the company notes that it still has plenty of heart-healthy lycopene from tomatoes in it, so anyone who switches to it won't be missing out.

Frankly, it's hard to imagine that a low carb ketchup will really stand up to regular ketchup, let alone to Organic Heinz, and because you don't generally consume ketchup by the cupful, how harmful could a few extra grams of sugar be? They're probably not has unhealthy as the French fries or other food that is being served with the ketchup in the first place.

The HJ Heinz Company has had the highest consumer satisfaction rating in the country for the past six years, and it's no wonder because, although they make many different products, they make one of the most popular and best loved condiments you can name: Heinz ketchup. Everyone likes Heinz, or at least, they think they do. Endless taste tests rank it sometimes higher and sometimes lower than other brands, and the brand still averages a high score. One recent test, however, may actually forecast a change in the way Heinz makes their ketchup. In it, Organic Heinz came out above regular Heinz.

For years, organic goods such as sauces and, of course, ketchup, had a hard time catching on with consumers since their flavors and consistency were too unfamiliar. Perhaps tastes have grown up a bit, or the technology is simply better, but if the organic version is now scoring higher with tasters, we could see a resulting increase in the availability of organic ketchup, possibly in place of the traditional stuff.

Where would you rank Organic Heinz? Is it as french-fry worthy as the classic?

Even though we already looked at some great commercials made in the 1980s, a post on TV Squad about a ketchup commercial starring a young, hip, ketchup-loving Matt LeBlanc is a good reminder that there were a fair number of entertaining commercials made then. Many were from Heinz, which ran a number of commercials touting how thick and rich its ketchup was - before people started to complain that it was so thick that they couldn't actually get it out of the bottle.

Heinz is coming to Russia in an effort to wrest market share away from Baltimor. America's most popular ketchup is synonymous with the condiment. So is Russia's.

Baltimor, which takes its name from the words for Baltic Sea, is associated with the word ketchup by 81 percent of the Russian population. And Russians are ketchup crazed, consuming more than three pounds annually. They use it on meat, fish, eggs and dumplings, among other things.

Now that Heinz has bought a majority stake in a St. Petersburg food manufacturer that's a major player in the world of condiments it has its work cut out.

Baltimor offers 15 varieties of ketchup. These range from the cayenne and chili-laced Ajica to Winter Garden, a sweet and sour ketchup with prunes. In case your wondering, Winter Garden is recommended for pizza, pelmeni, pasta and potato fries. Mmm...prune pizza.
