What this dot point is asking
The SQA wants you to use a range of cooking methods accurately, to know what each method does to food, and to choose a suitable and healthy method for a dish. These methods are demonstrated and marked in the practical activity and described in the question paper.
The methods that use water or steam
These moist methods cook food in or above hot liquid.
Boiling is quick and needs no fat, but vigorous boiling can break up soft food and the water dissolves out some vitamins. Steaming and poaching are gentler and keep more nutrients, which is why they are good healthy choices.
The methods that use dry heat or fat
These methods brown food and develop flavour.
What cooking does to food
Heat changes food in useful ways, and these changes explain why you cook in the first place.
- Softening and tenderising. Heat softens vegetables and breaks down the tough connective tissue in cheaper cuts of meat, which is why a tough cut is simmered slowly for a long time.
- Killing harmful bacteria. Cooking food to a high enough core temperature (at least 75 degrees Celsius in the centre) kills harmful bacteria and makes food safe to eat.
- Developing flavour and colour. Dry-heat methods such as grilling, baking and roasting brown the surface of food, which creates new flavours and an appetising colour.
- Setting and rising. Heat sets the protein in eggs and the gluten in dough, and makes trapped air and raising agents expand, so a cake or loaf rises and then sets.
Choosing a suitable and healthy method
The method follows from the food, the result you want and how healthy the dish needs to be.
- Suit the food. Soft delicate food (eggs, fish) is poached or steamed so it keeps its shape; a tough cut of meat is simmered or pot-roasted slowly to tenderise it.
- Suit the result. If you want a browned, crisp surface, choose a dry-heat method such as grilling or roasting; if you want food cooked gently right through, choose a moist method.
- Make it healthier. Grilling, steaming, poaching and baking add little or no fat, so they are healthier than deep frying. Grilling also lets fat drip away, and steaming keeps more vitamins, which matters when you are cooking to current dietary advice.
Common mistakes
Examples in context
Example 1. A vegetable side dish. A candidate steams broccoli and carrots rather than boiling them, so the vegetables keep more of their vitamin C and stay a bright colour, which also looks better on the plate.
Example 2. A browned, flavourful stew. A candidate sears diced beef in a little hot oil to brown it, then simmers it slowly in stock so the tough cut becomes tender while the browning gives a deep flavour.
Try this
Q1. Why is steaming vegetables often a healthier choice than boiling them? [1 mark]
- Cue. Steaming uses no added fat and, because the food does not sit in water, it keeps more of the water-soluble vitamins.
Q2. What is the difference between boiling and simmering? [1 mark]
- Cue. Boiling is a rapid, rolling bubble at 100 degrees Celsius; simmering is gentle cooking in liquid kept just below boiling.
Exam-style practice questions
Practice questions written in the style of SQA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
SQA N5 style4 marksDescribe two different methods of cooking, and for each give a dish that would be cooked that way.Show worked answer →
A 4-mark answer needs two methods described (up to 2 marks) and a suitable dish for each (up to 2 marks).
Method 1. Boiling means cooking food in water (or stock) that is bubbling rapidly at 100 degrees Celsius. It is used to cook pasta, or potatoes for mashing, where the food needs to soften right through.
Method 2. Grilling means cooking food by direct radiant heat from above (or below). It is used to cook bacon, sausages, or a piece of fish, where you want to brown the surface and let some fat drip away.
Other methods that would score include steaming (cooking in the steam above boiling water, for vegetables or a sponge pudding), baking (cooking in the dry heat of an oven, for cakes and bread), roasting (cooking in an oven with some fat, for a joint of meat or vegetables), and frying (cooking in hot fat or oil, for chips or an omelette).
Markers reward each method correctly described and a sensible matching dish. Naming a method with no description, or a dish that does not use it, loses the mark.
SQA N5 style3 marksA cook wants to prepare a healthy main course. Recommend a suitable cooking method and explain why it is a healthier choice.Show worked answer →
This question tests choosing a method for a healthier dish, so the answer must name a method and link it clearly to health.
Recommend grilling, steaming or poaching. Grilling chicken is a healthier choice because no extra fat is needed to cook it, and any fat in the food drips away through the grill, so the finished dish is lower in fat.
Steaming vegetables is healthier because the food cooks in steam with no added fat, and because it is gentle and uses no soaking water it keeps more of the water-soluble vitamins (such as vitamin C) than boiling does.
By contrast, deep frying adds a large amount of fat to the food, which raises the energy and saturated fat content, so it is a less healthy method for an everyday main course.
Markers reward a sensible healthier method (grilling, steaming, poaching or baking), and a correct reason such as no added fat, fat draining away, or keeping more nutrients.
