Dry Cooking Methods - Baking

Baking involves using dry heat to cook foods. Baking is generally done in an oven.

Baking

Baking

  • Foods commonly baked include potatoes, cakes, cookies, some desserts, bread and fish.
  • Food bakes quicker higher up in the oven because hot air in the oven rises.
  • Fan-assisted (sometimes called convection ovens) use fans to improve the circulation of air inside the oven.
  • The advantages of fan-assisted ovens include:
  • Less energy is used (the oven takes less time to heat up and cooks food more quickly).
  • As all sections of the oven are heated to a similar temperature, you get a more even bake.
Advantages of baking

Advantages of baking

  • Relatively healthy - no additional fat is needed, and baking tends to remove the fats in foods.
  • Browns the outer layers of food, which also turn crispy. This gives foods added flavour.
  • Can be used to cook a range of foods.
Disadvantages of baking

Disadvantages of baking

  • Can dry out foods.
    • To preserve some of the moisture in foods, bake them in foil.
  • Lots of energy is needed to keep the oven hot for long durations.
  • Slow cooking method.
Heat transfer in an oven

Heat transfer in an oven

  • When food is baked, heat energy transfers via:
  • Radiation.
  • Convection.
  • Conduction (throughout the food).

Dry Cooking Methods - Roasting

Roasting is a bit like baking. We roast foods in an oven using dry heat.

Roasting

Roasting

  • Commonly roasted foods include meat (e.g. pork or duck, often large cuts), vegetables (e.g. parsnips and carrots), and potatoes.
  • We usually roast foods at higher temperatures than we bake foods at, which means foods turn brown and cook faster.
  • To help foods preserve their moisture and brown quickly, people often add fat to the surfaces of roasting foods.
  • Basting involves adding fat from the food that's melted to the food's surface.
Heat transfer during roasting

Heat transfer during roasting

  • When food is roasted in an oven, heat transfers via:
  • Radiation.
  • Convection.
  • Conduction (throughout the food).
Advantages of roasting

Advantages of roasting

  • Roasted meat fat can be recycled (e.g. used to cook potatoes).
  • Roasted food often has a moist texture.
  • The brown, crispy outer layer is very flavoursome.
  • It's possible to cook meat to have an undercooked (rare) centre, which many people prefer to well-cooked meat.
Disadvantages of roasting

Disadvantages of roasting

  • Relatively unhealthy because of the amount of fat used.
  • Requires lots of energy.
  • Slow cooking method.
