A really high-quality, aged balsamic vinegar is something that no chef should pass up, as it is basically the standard to which all other vinegars aspire. Other vinegars have their uses, of course, but few will be coveting the taste of white vinegar to top off a nearly perfect dish. Aged balsamics can be expensive, though, and as a finishing touch to a dish or to enhance the flavor in a dressing or marinade, flavored vinegars can be great options.

Flavored vinegars are infused with everything from sweet berries to fiery chilies and they seem to be everywhere right now. Trader Joe's, for example, is carrying at least four kinds right now, including the ones pictured above: California Grapefruit, Mango Chili, Strawberry Balsamic and Pomegranate. The flavors tone down the astringency of vinegar, while retaining its brightening properties. Of the ones pictured above, Grapefruit and Pomegranate are delicious in salads, while Strawberry is good on desserts and Mango works well as a marinade.

If you can't find a flavor that matches your own tastes, you can make your own fairly easily, with fresh herbs, fruits and spices.

Rachael Ray will never again have to explain to her viewers what "EVOO" stands for because it is the name of her very own brand of extra virgin olive oil. The olive oil is being "specially produced in Italy for Rachael" and is almost guaranteed to turn "dish from so-so to 'Yum-o' in no time," so not only can you use in all of Rachael's recipes, but you can look at her smiling face on the bottle's label. Rachael's site notes that the oil is a certified Product of Italy, made from only Italian olives (just in case you were wondering if they imported theirs before processing for some reason). It is sold in 17-oz. ($8.95) and 34-oz. ($17.95) bottles.

Of course, she may not have to spell out "extra virgin olive oil" every time she mentions EVOO anymore, but don't be surprised if she starts including the web address of her online store in its place.

In honor of my oven-baked latkes, I decided to opt for a more health-conscious choice for the Cookbook of the Day today with Fry Light, Fry Right: Fried-Food Flavor Without Deep Frying because you don't have to eat a ton of oil just to enjoy the flavor of fried foods (or to celebrate oil, since today is the first day of Hanukkah).

Despite the holiday reference, this is not a Hanukkah oriented book. In fact, it's more about all-American fried foods of the variety that you'll find on hundreds of menus and in bakeries across the country, including things like Mozzarella Sticks, Coconut Shrimp, Chicken Fried Steak and Chocolate Devil's Food Donuts, among its 120 recipes. Each one is simple and all you really need to know how to do is work an oven to turn out impressive (and healthy) results. With only some heat and a little bit of oil, included primarily to prevent sticking and encourage browning, you should be able to obtain crisp exteriors and tender interiors on everything you make - just like deep fried foods, only there won't be as much fat to cover up the base flavors.

KFC announced yesterday that they intended to begin eliminating trans-fats from their recipes, starting with their famous fried chicken. Over the course of the next 6-8 months, by April of 2007, all KFC stores will switch to using a non-hydrogenated cooking oil, although some locations already use it. If this seems like a minor change, consider that one extra-crispy chicken breast (is there any other kind worth going to KFC for?) has 4.5 grams of trans fat!

The process of testing the recipes has taken the company about two years. Even though the partially hydrogenated oil that they currently use does not really contribute to the product in terms of flavor, it does produce a superior crispness that lasts longer than some other oils. The company did not want to put out a product that would not live up to their consumers' expectations - even if it was healthier. They will be using low linolenic soybean oil. Other fast food companies, including Pizza Hut and Taco Bell, which are also owned by KFC's parent company, Yum Brands Inc., say that they are looking into replacing partially hydrogenated oils on their menus, as well.

KFC fans should take note that there will still be a few things on the menu that will not be trans-fat free, namely their biscuits, macaroni and cheese and baked goods.

The British Heart Foundation (BHF) is mounting a campaign to educate Britons about "hidden salt, fat and sugar in common foods" to give people some perspective on the foods that they are putting into their bodies and to try to encourage healthy eating habits. Their focus, for the moment, is on crisps. A survey done by the BHF revealed that 49% of children from 8-15 ate at least one package of chips (crisps) each day, and 20% ate two or more. They are consuming roughly 5-liters of cooking oil every year at that rate, or about 1 1/3 gallons.

Crisp-addiction isn't limited to kids, though. As a whole, the nation consumes "a tonne of crisps every three minutes, enough to fill an Olympic size swimming pool every 14 hours." Using the number provided by the BHF, which says that the average 1.2-oz packet of chips has 2.5-tsp of oil, there are about 950-gallons of cooking oil consumed for every tonne (2,204 lbs) of crisps, a massive amount over any length of time.

When Nicole posted about Chicago's proposed city-wide ban on the use of trans fats in restaurants, she suggested that fast food restaurants would feel the strongest effects of the ban. Now the Chicago alderman that proposed the ban has limited it to only major restaurant chains, specifically those with at least $20 million in annual gross sales, according to the Chicago Sun-Times. The ban was apparently revised out of concerns that smaller independent restaurants could not afford the switch to pricier non-hydrogenated oils. Some feel that the ban is a positive move, while others still feel that their aldermans' time would be better spent on things other than cooking oil and foie gras.

Recently, someone asked me if there was a difference between the "zest" of a citrus fruit and the "peel." In short, the answer is yes. The peel is the name for the whole skin of the fruit, which is comprised of two layers: the zest and the pith. The zest is the colored, outer surface of the fruit while the pith is the soft, white inner layer. The vast majority of recipes will call for the zest of a fruit only. The pith is actually bitter and gives an unpleasant aftertaste if eaten, but the zest contains the very flavorful oils/essence of the fruit.

Once you know what the zest is, the question is how to get it off. The layer is very thin compared to the fruit as a whole, but it can be cut off with a knife and then chopped into fine pieces. A more efficient way is to use either a zester (pictured) or a microplane, both of which are tools that slice off only the zest from a fruit. A zester produces long, thin strips that need to be finely chopped, while a microplane naturally creates a very fine chop that needs no further alteration before being added to a recipe.

The New York Times recently featured a story about the tastings and tours offered by several California olive farms. Located mostly around Napa, many of these olive-growing, olive-oil-producing farms allow visitors to check out their facilities and sample what they produce. The article also gives some insight into the blend of old and new technology involved in harvesting olives and creating a variety of nuanced oils. There's also talk of the proper way to taste olive oil, which, if done correctly involves lots of slurping and coughing.

Nabisco makes more than a dozen varieties of Oreo cookies, not including the ones that have their fillings dyed for each holiday, in addition to 4 Oreo ice creams and 8 other Oreo-related products. They do not sell what is rapidly becoming one of the most popular types of Oreo, albeit the unhealthiest: deep fried Oreo's.

A popular fair and carnival food, just like the deep fried Snickers bars, it involves dipping an Oreo into a thick batter and popping it into a sizzling hot pot of oil. When pulled out, hot and crispy, they are topped with powdered sugar and served. According to many,  they are delicious and more easily justifiable than a Snicker's due to their relatively small size. One blogger described them : "The Oreo loses it's hard crunchy texture and becomes a warm chocolately cake delight. The creamy center melts and creates an inner glaze." Should you want to risk the health hazards of deep-fried foods for the delights of one of these treats, you can find instructions both here and here.

Sitting down with a bowl of oatmeal topped with fresh fruit for breakfast, you might be thinking about the big, but organically certified, farm that grew the oats, maybe the precious soil on the small farm that produced the fruit, but you certainly wouldn't be thinking about...crude oil.

SF Chronicle's Chad Heeter breaks down the amount of fossil fuel it takes to produce, package and distribute the foods we're eating. I've never thought about it that way, and his article is interesting. His breakfast of a bowl of imported McCann's Irish oatmeal topped with Cascadian Farms organic frozen raspberries, and a cup of Peet's Fair Trade Blend coffee add up to 8 ounces, one cup, of crude oil.

After disclosing that its fries contain more trans fat than the nutritional information claimed, McDonald's revealed that their frence fries also contain potential allergens from dairy and wheat. The fries had always been considered to be safe for customers with a gluten intolerance, as the suppliers of the potatoes remove all potential allergens before shipping them, but the flavoring agent that McDonald's uses has derrivatives of both wheat and milk ingredients.

The revelation comes following the laws passed at the beginning of the year which require companies to disclose potential allergens, including eggs, nuts, fish, shellfish, wheat and soy. The director of nutrition at the company says that proteins found in the wheat and dairy are what cause allergic reactions and that they are not present in the flavoring agent. She also notes that if you have been eating the french fries without experiencing an allergic reaction, you will be able to continue to do so.

Even if it does not affect those with allergies, vegetarians may be concerned that the fries contain ingredients derived from dairy.
