In both professional and personal situations, I am often asked about the appropriate ways to cook a particular item. My first questions invariably center around the obvious; what are you cooking, how does the product look, what type of cooking apparatus do you have, etc... My next questions may be slightly less obvious but just as important; what appearance are you looking for, what is the final flavors you desire, what else are you serving. All of these considerations are very important in deciding the most appropriate method to cook a particular item.
There are two predominate cooking methods of cooking. Your chosen method will vary depending on the type of food cooked and the desired outcome. Generally, with the exception of braising (my personal favorite) you will choose either dry heat cooking or moist heat cooking method.
Dry Heat Cooking
The dry heat cooking method, at the most elementary level, involves cooking a food item in the absence of a liquid. In dry heat cooking, heat transfer to the product takes place through a dry medium such as air, direct metal or stone, cooking oil (explained in a bit) or directly in the flame. Examples of dry heat cooking are:
- roasting/ baking
- grilling
- broiling
- sauteing
- deep frying
- and pan frying.
In order for dry heat cooking to be effective, you generally want a temperature above 300 degrees. This will allow a process called Maillard Reaction (caramelization of the proteins and amino acids in meat, caramelization of natural sugars and starches in vegetables) to occur and will give your product a nice color and aroma. Dry heat cooking is best suited for cuts of meat that are less tough and do not require a liquid to help break down the muscle fibers for tenderness. Dry heat will help to evaporate any water in the product and concentrate the flavors.
One note about deep frying or cooking with oil is that this method of cooking is definitely a dry heat process. Since oil is not water soluble, there is no transfer of liquid to the product and there is the opportunity for caramelization of the outside of the product. Deep frying as a dry heat cooking method is, of course, predicated on cooking at the proper temperature...remember, above 300 degrees. If you are cooking much lower than that, you are actually poaching the product in the fat and you have a much different dish altogether.
Moist Heat Cooking
Moist heat cooking utilizes a liquid as the medium for heat transfer. This cooking method is usually performed with lower heat and over longer periods of time. Remember from high school physics that water boils at 212 degrees (at sea level) and will not let the temperature rise above that point until all the liquid in the system has evaporated...212 degrees is the hottest the cooking liquid will get unless you put it under pressure.
The act of cooking with moist heat at moderated temperatures and extended time periods will result in a moister, more tender product...IF DONE CORRECTLY. Proper temperature control of both the cooking medium and the actual product are crucial in cooking with moist heat. Contrary to popular belief, is entirely possible to have a dry, tough product even if cooking in liquid. To test this statement, take a chicken breast and boil it until the internal temperature of the chicken is 170 degrees, remove it from the liquid and let it cool a few minutes...dry chicken.
Since moist heat cooking usually involves some sort of flavor transfer, it is best to make sure your cooking medium is tasty. Flavor your broth well, fill your steaming liquid with aromatics and make sure you add plenty of other ingredients in your stew to ensure a tasty finished dish.
The most common moist heat cooking methods are:
- poaching
- simmering
- boiling
- steaming
- sou vide
- and braising.
Braising is actually a combination of dry and moist heat cooking and incorporates a brief initial browning of the meats for flavor and appearance then is followed by a low and slow cooking process to allow for maximum flavor transfer and tenderness....thus, my favorite way to cook!
I encourage you to test the different cooking methods to see how each procedure affects your finished dish. If you learn a couple basic techniques in each method, your repertoire, versatility and confidence will be greatly increased.
