The bowl and whisk must be perfectly clean and dry, with no traces of oil or fat.
Place the whisk in the bowl with your egg whites, remove the cap from the lid, then start the EGG WHITES programme. It is vital that you remove the cap, otherwise your egg whites will not be light and airy. For fluffier egg whites, make sure your eggs are at room temperature and add a pinch of salt. With the EGG WHITES programme, the whites will be extremely fluffy, so for a stiffer finish (e.g. for meringues), increase the speed to 7.
