Recently, I received a wireless thermometer from Thermoworks to try out. Their newest product is called Smoke and is specifically designed to help people barbecue and smoke food at home. Smoke has two parts - a base unit (which takes two of Thermoworks standardized Pro-Series probes) and a wireless receiver unit - which lets the user track the air temperature and the food temperature without going outside to the smoker.
Thermoworks is selling the Smoke at $99 and this would definitely welcome tool for anyone who likes to slow cook food outside.

These days when I reach for a spatula to turn food in a pan, I've been finding myself grabbing the GastroMax Slotted Turner more often than not. Tina bought this spatula for me after months (or maybe years) of listening to me complain about our various spatulas. After buying the GastroMax Turner, my complaining has stopped.

The smoke point of various fats is important to note because a fat is no longer good for consumption after it has exceeded its smoke point and has begun to break down. Once a fat starts to smoke, it usually will emit a harsh smell and fill the air with smoke. In addition it is believed that fats that have gone past their smoke points contain a large quantity of free radicals which contibute to risk of cancer. Refining oils (taking out impurities) tends to increase the smoke point. The table below lists some ballpark values for smoke points of various common fats. I like cooking with extra light olive oil and butter. This is mainly because olive oil is high in monounsaturated fatty acids (73%) while being low in polyunsaturated fatty acids (less than 10%). The refined nature of extra light olive oil mainly affects taste and smoke point, but does not reduce the nutritional benefits of olive oil. Butter, although high in saturated fat (66%), is low in polyunsaturated (4%) and contains a host of vitamins, antioxidants, essential fatty acids, and acids that are antimicrobial and antitumorigenic. Also, it tastes good.

This method of making clarified butter uses basic utensils found in every kitchen and produces a high yield of very pure clarified butter that can be accomplished even by novice cooks on the first attempt. There is no cheese cloth and no filtering. This method is unorthodox for the kitchen, but is well at home in the organic chemistry laboratory.
