Small batch baking recipes often require less than one egg to be used. Here are some useful tips to help portion your eggs.

Eggs used in BakeClub recipes are 59-60g/2oz eggs (with shell) and are sold in a 700g/1lb 8oz carton.

• With the shell removed weight of the whole egg = 52g
• Approximately ⅔ of the weight of each egg is the white = 35g
• Approximately ⅓ of the weight of each egg is the yolk = 17g

When using recipes that specify less than 1 egg always whisk the whole egg together before measuring out the quantity required.

If a recipe calls for just egg yolk/s or egg white/s the remainder of the egg can be portioned and frozen in ice cube trays for use later on as required (whisk egg yolks with a good pinch of salt before freezing). Once frozen, transfer to a snap lock bag, label and freeze for up to 3 months. Thaw in the fridge. Use egg whites for meringue and Swiss meringue buttercream, and egg yolks in custard, curds or to add extra richness to your cookies and cakes.

I often get asked how long should you beat butter and sugar when creaming it. There is no actual time that you need to aim for as there are a few variables that can affect how long it will take, including how soft your butter is, the proportion of butter to sugar, and the type of sugar you are using.

The best thing to watch out for is for how the mixture transforms as it is beaten. The more you beat it the paler in colour and lighter in texture it will become, but it will get to a point that it won’t change any more and this is the stage that you will know you have creamed it ‘enough’. If you are unsure of what you are looking for it is a good idea to take a small sample of the mixture at intervals as you beat and it will soon become clear.

This image shows a creamed butter and sugar mixture at five stages (from bottom to top): the first one is just combined, with the following samples taken at intervals of beating every 1-2 minutes. The final two samples (at the top), with no difference between them, indicate that the mixture has been creamed enough.

So remember, when creaming, it isn’t a matter of time, just a matter of transformation.

When whisking eggs for your baking it is always best to use the freshest eggs possible.
Here’s why:

Eggs, when fresh, are acidic and this acidity means that the egg proteins are tightly knit. You can see this egg is fresh because the yolk is plump and round and the inner white is clearly defined and is holding onto the yolk tightly – an indication that those protein bonds are keeping it from spreading on the plate.

As an egg ages, it becomes more alkaline and the proteins start to pull away from each other, causing the yolk to lose it's form and the white to become thinner and more likely to spread on a plate when cracked. 

So why is this important when whisking eggs? Less fresh eggs will whisk to a foam more quickly than fresher ones, and you’ll achieve a slightly greater volume, but the resulting foam will be less stable than one made with fresh eggs. A fresh-egg foam will be more stable thanks to the strong protein bonds and therefore more likely to holds its shape and retain the air you have incorporated through whisking.
