On the size of eggs

I often don’t have the correct size of eggs in to follow a recipe.  If I only have large eggs, how many should I use when the recipe calls for small eggs?  With only medium yolks, how many should I use when a recipe calls for small yolks?

Small eggs weigh approximately 50g, medium eggs 60g, and large eggs 70g.  Large eggs are roughly 15% larger than medium eggs (70 / 60 = 1.17), and small eggs are roughly 15% smaller than medium eggs.

For example, if you only have large eggs, but a recipe calls for 6 medium egg yolks, do the following sum:
6 x 20g of yolk [from picture above, showing a medium egg] = 120g.  Large egg yolk weighs 15% more than a medium egg yolk, or 1.15 x 20g = 23g.  120g of yolk in large egg yolks = 120/23 = 5.2 yolks.  This rounds to 5.  So for 6 medium egg yolks, you will only need 5 large ones.

Yes, it’s tough without a calculator, but memorising the picture above definitely helps!

French whites: searching for value, and is a booze cruise worthwhile?

I spend much of my time drinking wine and thinking about food, or eating food and thinking about wine.  Over the last few years I’ve sought out wines for our wedding list, studied with the Wine & Spirits Education Trust, and spent a not inconsiderable amount of time hosting others and drinking.  This all comes at a cost, and I’ve been searching for cheaper ways…
