STEWING

This is a method of cooking food slowly in a well-covered pan containing little liquid for a long time. The food is served with the water.

This is the process of cooking food in hot oil or fat. Some foods need to be coated before frying.

TYPES OF FRYING

  1. SHALLOW FRYING: This is frying with just little amount of oil to cover the surface of the frying pan and to prevent burning. Suitable for frying are pan cakes, omelettes, fish, etc.

 

Types of Shallow Frying

  1. a) Sautéing: This is a method of frying foods quickly in a shallow pan of hot fat/oil, turning it until it is evenly browned. It is used for preparing only tender foods such as small cuts of meat, fish, vegetables, etc. It can also be used for flavouring foods (especially vegetables) used for garnishing e.g. tomatoes, onions, green pepper, etc.
  2. b) Griddle frying: Foods can be cooked on lightly oiled griddle pan or metal plate and turned frequently during cooking e.g. sliced onions, sausages, hamburgers, etc.
  3. c) Stir frying: This is fast frying in little oil using flat pan. Usually vegetables, meat or chicken cuts into stripes are cooked this way.

 

  1. DEEP OR FRENCH FRYING: This is when a lot of oil or fat is used in cooking foods. The oil is usually poured in a deep pan and is heated to boiling point; then the food is put inside the oil. The oil used must cover the food. Suitable foods for deep frying are chin-chin, doughnut, puff-puff, bean cakes, etc.

 

  1. DRY/SELF FRYING: This is a method used for foods which already contain fat. The fat melts and runs out of the food. It requires less heat. Bacon, herrings, sausages, etc. can be cooked this way.

  1. Melting stage – Fat melts from solid to liquid form.
  2. Bubbling stage – When oil is being heated. The water in the oil boils out giving a bubbling sound.
  3. Frying stage – Here the bubbling sound ceases and blue haze smoke is produced.
  4. Decomposition – When the oil is over heated, it charred and brings about irritation of the throats.
