As promised, here is the second installment of using up leftover eggs! This time, we tackle the yolks. Although, if you're like me, you'll be making at least one of these recipes even if you don't have any "leftover" yolks. Just jump over here once you have those extra whites! 

Storage

Fridge: 2-4 days. Just make sure they don't dry out. So, if yolks are intact, cover with a bit of water (which you'll discard before using in a recipe) or if yolks are accidentally broken, cover with plastic wrap so that it clings to the surface.

Freeze: They don't freeze well. So get baking!
