What do you do with a surplus of egg yolks? The obvious answers are to make custard or ice cream or mayonnaise, or something else that uses egg yolks. But sometimes we don’t always want to make something just to use something else up. When I separate eggs for a recipe, most often I end up with a ton of egg whites. On occasion, though, I have leftover egg yolks and if I’m not using them immediately (such as using them in custard) I save them for future use by freezing them.
There is a way to freeze egg yolks and still be able to use them afterward, which is by stabilizing them. Egg yolks are gelatinous and they need a stabilizer, otherwise when you thaw them they won’t return to their previous state. A stabilizer is usually a sweetener, such as sugar, or a preservative like salt, depending on what you plan to use the yolks for.
