When bakers talk about retarding, they're not being insulting. They're talking about slowing down the fermentation process.

Retarding is the process in which a baker uses refrigeration to slow down yeast activity. This has a couple of benefits, one of which is to get better flavor out of the finished bread. The longer the yeast can ferment, the more organic acid is produced, which makes the bread taste better and also leads to a longer shelf life.

The other benefit of retarding dough is to give the baker more time to work. For a home baker, if something comes up to where you just don't have time to finish your bread, uou can refrigerate your dough just after mixing or just after the final shaping.

Mix the dough as usual, then refrigerate for up to 12 hours, after which you can let it come back to room temperature and continue the first fermentation. After the first fermentation and shaping, the dough can be refrigerated again (for up to 12 hours). Just allow the dough to come back to room temp and finish the final fermentation and then bake as usual. Just make sure that the dough is well covered in plastic before refrigeration to prevent a skin from forming.

Salad-On-Ice is not a failed icecapades routine. It is a well-designed bowl that might just be the perfect salad server.

There is nothing worse than a bowl full of lettuce that sits out at room temperature too long and looses its crunch. Salads should be crisp and refreshing (although some might be a little worried about eating lettuce at the moment), but you can't keep running back and forth to the refrigerator for seconds and third helpings, especially not when you are entertaining. Salad-On-Ice is a bowl that has a hollow stand designed to be filled with crushed or cubed ice to keep salads cold and fresh throughout an entire meal, even during a hot summer barbecue. It is made of shatter-resistant acrylic and comes with a lid and a pair of serving utensils.

The bowl would also work well for fruit salads, pasta salads or even chilled desserts, like trifle.

Of all the households in the US, 99.5% have refrigerators. About the same percentage have some way of heating food. We've seen some great gadgets for keeping things hot and cold here on Slashfood, but I want to show you an ancient technique for keeping food cool. It's called a zeer pot. The vessel itself may be third world, but it's playing a timely role in the continuing recovery of northern Darfur and other African nations. Science in Africa magazine states that a zeer can keep tomatoes edible for 20 days, as opposed to two, and meat two weeks, as opposed to a few hours.

A zeer pot is quite simple. It's basically two large earthen pots, one nested in the other. The space is filled with sand and water is added. A damp cloth covers the top. As the water evaporates, the inner pot containing the perishables is kept cool in the same manner that a mechanical refrigerator operates -- water evaporation draws heat from the inner vessel. Water is added twice a day.

Muhammed Bah Abba is credited with reviving (some say inventing) use of the zeer and has his own instructions on theory, application and making one. I am going to make one of these myself and see how long basic vegetables will keep at room temp. You can see from the picture how easy it would be to improvise a zeer with regular flower pots. I will then give it a taste test after one week.

Generally, to keep foods fresh longer, we wrap them up and place them in the refrigerator. Sometimes, we don't give much thought to how things should actually be stored or whether we're doing it properly. As a result, you are more likely to get food poisoning at home than when eating out at a restaurant where health codes are strictly enforced. Some of the biggest food safety violations have to do with the refrigerator, the catch-all of food storage. Here are a few tips to keep you, and your family, a little safer.

• The refrigerator should be kept at, or below, 40°F. Keep in mind that the temperature can rise when the door is opened frequently and if the fridge is overcrowded and air cannot circulate.
• Store raw meat that you won't be eating right away in the freezer, not the refrigerator. Defrost it in the fridge.
• Milk is good for about 10 days past its "sell-by" date, although if it is left out to warm up, it can go bad before that time. It is better to keep it in the main part of the refrigerator than on the door.
• Fruits and vegetables can be stored at the same temperature they are stored in the store, though cut produce should be refrigerated and eaten within a few days.
• Hard cheeses can be stored, wrapped, for several weeks. If mold develops, the affected area and about 1/2-inch around it should be removed; the rest is safe to eat. Do not eat soft cheeses or dairy products, including cream cheese and yogurt, that have molded.
• Fresh eggs will last at least 3 or 4 weeks in the fridge, but hard-cooked eggs will only last one week. You can always check your eggs for freshness if in doubt. Eggs blend better with other ingredients in recipes for baked goods and get more volume when beaten if they are held at room temperature for 20 or 30 minutes before using.

Researchers at UC-Davis have found that cut fruit left in the refrigerator doesn't lose nearly as much of its nutritional value as they thought, according to the Chicago Sun-Times. Over a nine-day period, six different types of cut, refrigerated fruit were compared to uncut, refrigerated samples and tested for amounts of vitamin C, carotenoids and phenolics. Sliced watermelon only lost 5 percent less C than whole watermelon and it retained the same amount of lycopene, the CS-T reported. One conclusion reached was that visual appeal and taste fade well before nutritional value does.
