escape if the liquid in which they are contained is thick.

2. Similarly, the mixture should not be overly mixed once the egg whites have been added to the

base. Overly mixing causes air bubbles to be lost, so it is often recommended that mixtures

are only “lightly folded” with a spatula rather than vigousously mixed with a spoon. The

process of folding will only disturb the air bubbles at the mixtures surface, so only air from this

part will be lost.

3. The souffle should be cooked straight away after preparing the mixture (especially if the base

is fairly liquid) to ensure that maximum number of bubbles are preserved in the preparation.

4. The base to which the egg whites are added should have a strong flavour -the addition of

beaten egg whites will dilute the original flavour

5. It is often better is the mixture contains other proteins sources. Adding extra proteins to the

base helps reinforce the proteins network that surrounds the air bubbles, reducing the

chances that they escape.

6. Butter is often added to the pan before the souffle base is added – this is merely for practical

purposes - during cooking, the butter will melt, and will act as a lubricant to allow the souffle to

be removed more easily from the cooking pan.

Use of eggs in cooking: how to cook egg yolk foams (e.g. sabayon)

Since egg yolks also contain proteins which are readily denatured, egg yolk proteins can be used to

make stable mousses. However, because egg yolks contain less water compared to egg whites, to

obtain a mousse like the one achieved from beating egg whites, a little water may need to be added to

the egg yolks, in order to improve the protein-water ratio and enable it to stably incorporate air bubbles

as effectively as egg whites.

To make an egg yolk mousse, called a sabayon, egg yolks (usually pre-mixed with sugar to improve

the taste) are whisked and mixed with a soft wine (to increase the water content of the mixture). The

process of whisking the mixture introduces air into the preparation as well as encouraging protein
