What this dot point is asking
Eduqas wants you to know the practical skills and cooking methods used to prepare and cook food, how different methods affect nutrients, and how to choose the right method and equipment for a dish. This underpins the NEA practical work.
Preparation skills
Safe knife use (the bridge and claw grips, a stable board) and good hygiene run through all preparation.
Cooking methods
Cooking methods are grouped by how heat reaches the food:
- Water-based (moist) methods: boiling, simmering, steaming, poaching, stewing and blanching use hot water or steam (mainly convection). They suit vegetables, pasta, rice, eggs and tougher cuts of meat.
- Dry methods: grilling, baking, roasting and dry-frying use dry heat (radiation, convection and conduction). They brown food (dextrinisation, caramelisation, Maillard) and suit bread, cakes, meat and fish.
- Fat-based methods: shallow frying, deep frying and stir-frying cook food in hot fat or oil (conduction). They are quick and add flavour and crispness but also add fat.
How cooking affects nutrients
To keep vitamins, cook vegetables for the shortest time in the least water (steam, microwave or stir-fry rather than long boiling), prepare them just before cooking and do not cut them too small, serve them straight away, and use the cooking water in a sauce so dissolved vitamins are not wasted. Choosing steaming over boiling and grilling over frying also gives a healthier result.
Choosing the right method and equipment
Match the method to the food and the goal: a tough cut of meat needs slow, moist cooking (stewing or braising) to become tender; green vegetables keep colour and vitamins best when steamed or stir-fried briefly; a cake needs baking; and a healthy dish avoids deep frying. Choose equipment to suit (a steamer, a heavy pan for frying, a sharp knife for preparation), and consider time, energy use and the result wanted.
Try this
Q1. Name one cooking method that keeps more water-soluble vitamins than boiling. [1 mark]
- Cue. Steaming (or stir-frying or microwaving).
Q2. Give two reasons frying is less healthy than grilling. [2 marks]
- Cue. Frying adds fat and so extra energy (calories); grilling lets fat drain away and adds none.

Eduqas 20186 marksCompare boiling, steaming and frying as cooking methods, including their effect on nutrients and healthiness.Show worked answer →
A 6-mark extended-response question. Mark it for a real comparison covering method and nutrition.
Boiling cooks food in hot water by convection. It is simple but water-soluble vitamins (B group and C) leak into the water and are lost, especially if vegetables are overcooked or cut small, so it can reduce nutrients.
Steaming cooks food in the steam above boiling water. It keeps more of the water-soluble vitamins because the food is not sitting in water, and adds no fat, so it is a healthy method that also keeps colour and texture well.
Frying cooks food in hot fat or oil by conduction. It is quick and gives good flavour and a crisp texture, but it adds fat and so energy, making it less healthy, especially deep-frying.
Top-band answers (5 to 6 marks) compare the three methods and judge them on both cooking effect and nutrition (vitamin loss and added fat).
Eduqas 20214 marksExplain two ways a cook can reduce the loss of vitamin C when preparing and cooking vegetables.Show worked answer →
A 4-mark question linking technique to nutrient retention.
Vitamin C is water-soluble and destroyed by heat and air, so it is easily lost. Two ways to reduce the loss (any two): cook vegetables for the shortest time in the least water (steam, microwave or stir-fry rather than long boiling); prepare them just before cooking and do not cut them too small, to limit the surface exposed to air and water; serve them straight away rather than keeping them hot for a long time; and use the cooking water in a sauce or gravy so the dissolved vitamins are not thrown away.
Markers reward two valid techniques, each linked to why it preserves vitamin C (less water, less heat, less time, or less exposed surface).
