One of the popular search on "Pebble Soup" is "Can I freeze egg yolks", I looked into this some time ago and the answer is ......Yes.
With the nice weather on the horizon, it is time to bake meringues and Pavlovas so for sure the Yolky issue is going to present itself once more.
Here are some ideas:
Make a custard, which you can then freeze. I freeze soups and sauces in plastic pint glasses, easily disposable when I defreeze the sauce.
Make your own hollandaise sauce, yummy.
use the yolks instead of the whole eggs to make a cake it will change the texture slightly.
same with quiche lorraine, use half whole eggs, half yolks only.
