Dry Heat Cooking Methods



In this article, we are going to examine the different types and techniques of dry heat cooking. Dry heat cooking generally uses higher temperatures to cook foods than moist heat cooking methods because air, fat, and metal can be heated to temperatures much higher (300°F or more) than the boiling point of water which is 212°F. While moist heat cooking methods transfer heat to food through a liquid, dry heat cooking methods transfer heat to foods through air, fat, metal, and/or radiation. For more information regarding moist heat cooking methods, check out my article on our blog Moist Heat Cooking methods.

Meats, vegetables and seafood cooked using moist heat techinques may get light applications of salt and pepper before cooking, but for the most part the flavor and seasoning for the dish comes from the sauce or juice in which it is cooked, or the accompanying sauce in which they are served. Foods cooked using dry heat techinques on the other hand, get their flavor and seasonings from a variety of different applications depending on the specific technique employed.

Roasted and baked meats tend to get liberal applications of salt and pepper and are basted during the cooking process to not only help keep the meat from drying out, but to evenly distribute seasoning on the surface of the meat, whereas broiled meats are more likely to marinated before cooking. Grilled meats may be marinated or rubbed with wet or dry spice rubs and or mixes prior to cooking and finished with a sauce during the last 15 minutes of grilling. Foods that are deep fat fried may be marinated or seasoned with dry spices before the application of the batter. In addition, the dry portions of the batter (flour, bread crumbs, cereal, etc...) as well as the wash or dipping liquid may be seasoned as well. On top of all that, fried foods such as 'chicken hot wings' may be coated with a sauce after frying to add an additional flavor component to the food.

As with moist heat cooking methods, many of the dry heat cooking methods are similar and may at times overlap or may be used in combination in a particular recipe. In fact, even moist heat and dry heat methods can be used in conjunction to cook foods such as pork ribs which may be blanched or poached (moist heat) before being grilled (dry heat). Having said that, it is important that the home cook know the subtle differences of each technique to help them employ the best cooking options for the food they wish to purchase and prepare. The Dry heat cooking methods that we will be discussing today are generally broken down into three primary categories 1) roasting and baking, 2) broiling and grilling, and 3) frying.


Roasting and Baking

The terms roasting and baking are used interchangeably by many chefs in that they both describe a hot dry air method method of cooking foods generally inside your oven at temperatures greater than 300°F. Despite their similarities, roasting generally refers to the process of cooking meats, poultry and vegetables, and baking generally refers to bread, pastry, cakes, and cookies. Delicate foods such as fish and other seafood are also considered to be baked, as opposed to roasted. When in doubt, just remember that roasted foods are cooked at quite a bit higher temperature than baked foods. This higher temperature causes the foods to not only cook faster, but have more pronounced browning.

Both roasting and baking cook foods fairly evenly as all of the food's surfaces are exposed to the same air temperature. As mentioned previously, these two dry heat methods use hot air to transfer heat to food yielding a wide variety of results depending on the temperature, rack position, and type of baking dish used. Unlike baking, foods that are roasted are often basted with a fat or other liquid to prevent them from drying out during the cooking process. Roasting differs from pan-searing, a technique in which the surface of the food that touches the hot pan gets much hotter than the side that facing up. When roasting or baking, the food is cooked uncovered, so that the hot, dry air cooks the food rather than the steam from the food. Roasting of meats in dry heat allows the meat to not only brown, but develop complex flavors that just cannot be attained using moist heat cooking techniques.

Roasting and baking can be performed in a conventional or convection oven. The choice of the type of oven does not affect the technique, but it may affect the time necessary to cook the food. Cooking foods in a conventional oven uses uncirculated hot air, whereas a convection oven uses a fan to force air to circulate over and around the food as it cooks. Convection cooking transfers heat more quickly and efficiently to foods thereby decreasing the cooking time (20 to 30%) of foods compared to a conventional oven.


Broiling and Grilling

Broiling and grilling, like roasting and baking are dry heat cooking techniques that rely on heat conducted via the air to cook food. The difference being that foods that are broiled or grilled are cooked at higher temperatures. While they two techniques (broiling and grilling) are different, they produce similar results. Because air is a relatively poor conductor of heat, broiling and grilling require the food to be quite close to the heat source, which may be an open flame or heating element. Thus the surface of the food cooks very quickly, making this type of cooking ideal for poultry, fish and the tenderest cuts of meat. In fact, due to the extremely hot and dry nature of these cooking methods, most meats that are broiled or grilled are marinated prior to cooking. With both techniques meats and or vegetables are typically cooked on a grid or grate of some kind and are turned at least once during cooking which gives the food the distinctive grill marks that are the hallmark of these cooking techniques. As with sautéing, preheating the broiler or grill prior to putting the food on it is essential to achieve the desired results.



As mentioned previously, broiling is the technique of placing food in the oven very close to a heat source located above the food that can attain very high temperatures in a short period of time. Most home ovens only have one temperature setting for broiling and the amount of heat applied to the food is controlled by moving it closer or further away from the heat source by adjusting the grates in the oven. In many instances broiling is a finishing technique used to brown baked meats or other casserole type dishes.

Grilling, like broiling, uses very intense high temperatures to cook meats, vegetables, and on occasion seafood. Unlike broiling however, the heat source is located beneath the food to be cooked. The heat source for grilling can come from either direct or indirect flames from either gas, charcoal or wood, or direct or indirect radiant heat from charcoal briquettes.


Pan and Deep Fat Frying

Frying is a dry heat cooking technique that uses fat (butter, oil or shortening) to transfer heat to food. Because frying does not involve the use of water or stock it is considered a dry-heat cooking method. Techniques such as sautéing, stir-frying, and pan frying are all methods for frying food that use a small amount of fat to give cooked foods a brown and crispy texture. If you've ever seen the violent reaction of hot oil when water hits the pan or deep fat fryer, you know full well that oil and water just don't play well together. Getting a burn from hot oil can ruin any aspiring cooks day, take it from me, been there, done that, got the t-shirt. To minimize your chances of being burning from hot oil splatter, make sure anything you place into the hot fat is free from excess moisture before frying. For non-battered items, I recommend that you pat the food dry with a paper towel before frying it.

Deep fat frying is one of those cooking techniques that at first glance appears to be a moist heat technique. However, since deep frying requires food to be totally submerged in a hot liquid fat, it is actually a form of dry heat cooking. Foods that are deep fat fried are usually coated in a simple batter to protect and seal in its moisture as well as giving it that attractive golden brown color associated with foods cooked using this method.


 

Optimum deep fat frying is done in oil that has been heated to a minimum of 325°F and a maximum of 400°F. Any hotter than 400°F and the oil may begin to smoke, if the temperature of the oil drops below 325°F, the oil will begin to soak into the batter as well as the food making it greasy. When cooked properly, deep fat fried items actually have very little oil on or in them and when used in moderation can be a healthy addition to any diet. The most effective way to keep the oil hot is to fry items in small batches, so that the oil does not cool off too quickly. Overcrowding your frying vessel will cause the oil temperature to drop drastically increasing the amount of oil the food absorbs (up to 2 to 3 times the amount) making it soggy, greasy and extremely unhealthy. I am not saying frying is healthy, rather the technique of frying can be healthier when foods are fried properly.


Conclusion

Knowing how to use the proper dry heat cooking method is an important skill for the home cook or anyone who is cooking on a budget. Like moist heat, using the correct dry heat technique allows you to properly cook meats which are tender, juicy, and delicious that your family will surely enjoy. Whether you are roasting or baking in the oven or using a faster and higher temperature technique such as broiling, grilling or deep fat frying, knowing which foods work best with each technique will serve you and your family well.
