If I can't get cure on them within 1-2 days I won't use them, they break down too fast. So I always try to have some type of curing product on hand.

I use the 3-2-1 cure; 3 parts borax, 2 parts sugar, and 1 part kosher salt. If you pre-mix this and keep it in a sealed container you'll always have some ready when you get home.

If I intend to freeze them, I'll add some jello to teh eggs during the curing process, the pectin helps prevent freezer burn, also adds a deeper color to the eggs if that's what you are looking for.

Good luck.
