# Water-Based Cooking Methods

Food Preparation & Nutrition: AQA GCSE, topic 3.1.2

## Water-Based Cooking Methods

We use water for lots of different forms of cooking. For example:

### Steaming

![Steaming](https://image-v2.cdn.app.senecalearning.com/2018-05/ee9c6a9b-86b6-4535-8218-bfee84ab4d1b/shutterstock_513390529.jpg)

- Using steam (from stock or boiling water) to cook food. 
- Chicken, seafood and vegetables are all foods that can be steamed.
- When food is steamed, heat energy transfers via:
 - Conduction: from the pan → liquid → through food.
 - Convection: through steam.

### Advantages of steaming

- Fat not used.
 - Healthiest cooking method.
 - Compared to boiling, vegetables retain more of their texture, colour, nutrients and flavour.
 - Gentle cooking method - good for tender ingredients (fish).

### Disadvantages of steaming

- Food may not be as flavoursome as roasted or fried food.
 - Gentle cooking method - not good for tough foods (meats).

### Boiling

![Boiling](https://image-v2.cdn.app.senecalearning.com/2018-05/a0b1776c-9bce-4987-b581-6afbcb57b12c/shutterstock_271851755.jpg)

- Heating food in boiling water (or another liquid).
- Lots of foods can be boiled, including eggs, pasta, potatoes, rice and vegetables. 
- When food is boiled, heat energy transfers via:
 - Conduction: from the pan → liquid → through food.
 - Convection: throughout the liquid.

### Advantages of boiling

- Fat not used.
 - Healthy cooking method. 
 - Low energy (if little water is used and the pan is covered).

### Disadvantages of boiling

- Harsh cooking method. Delicate foods break up.
 - Over-boiling can make foods soft or mushy. Vegetables lose vitamins and flavour.
 - Food tends to be less flavoursome than fried or roasted food.

## Water-Based Cooking Methods

We use water for lots of different forms of cooking. Examples are:

### Blanching

![Blanching](https://image-v2.cdn.app.senecalearning.com/2018-05/3931f5f9-5ad7-4dc5-83a7-d4f59306ad8a/shutterstock_132863963.jpg)

- Boiling food for a short time to part-cook it, before placing the food in cold/icy water.
- Foods that can be blanched include broccoli, leafy greens, string beans, okra, and asparagus before freezing. 
- Advantages:
 - By placing the food in cold water, we stop cooking the food. The food keeps more of its colour, texture and vitamins.
 - Can take away harsh flavours.
 - Makes removing food skins easier as skins shrivel.

### Simmering

![Simmering](https://image-v2.cdn.app.senecalearning.com/2018-05/cf986e65-7a7f-4cfa-b430-cda6c5c78af3/shutterstock_248363116.jpg)

- A gentler form of boiling as the liquid is not heated to boiling point.
- Fish, curries and root vegetables can be simmered.
- Advantages:
 - As simmering is less harsh than boiling, food doesn't lose as many nutrients.

### Poaching

![Poaching](https://image-v2.cdn.app.senecalearning.com/2018-05/57f1717c-8bf7-404b-9af6-f3c975d779cf/shutterstock_471501371.jpg)

- A gentler form of boiling as the liquid is heated to below boiling point (approximately 80°C).
- Eggs, chicken, fish and fruit can all be poached.
- Advantages:
 - Gentle cooking method - food stays tender.
 - Can absorb flavours if poached in a sauce.
- Disadvantages:
 - Some flavour and nutritional value is lost because flavours and nutrients transfer to the liquid.

### Braising

![Braising](https://image-v2.cdn.app.senecalearning.com/2018-05/774f45ad-1301-454e-a321-3a73a45e89c9/shutterstock_496497469.jpg)

- A combination of simmering and steaming. Food is cooked in a sealed pot containing liquid (e.g. water or wine).
- Advantages:
 - Gentle cooking method - tough meats are tenderised.
 - Any meats being cooked absorb flavours from the other ingredients in the pot (e.g. the liquid, vegetables, herbs).
 - If meats are flash-fried before, the meat retains its juices better.

### Conduction and convection

![Conduction and convection](https://image-v2.cdn.app.senecalearning.com/2018-05/547c13c5-1223-4dd6-bac7-c0688427f42c/shutterstock_32565448.jpg)

- When food is poached, heat energy transfers via:
 - Conduction: from the pan → liquid → throughout food.
 - Convection: throughout the liquid.
- When food is braised, heat energy transfers via:
 - Conduction: from the dish → liquid → throughout the food.
 - Convection: throughout the liquid/steam.
