This has become my egg-freezing bible since Marilyn first posted it. 14 is an odd number,
I freeze them 2 at a time, beaten with a small pinch of salt, in little pimento jars.
You can do them in 2's, 4's or a combination of them, just beat with a bit of salt or sugar and freeze.
Truly, the only imperfections I've found from defrosted yolks were in a custard sauce, which had to be strained to be smooth. But custard sauces are best strained anyway.
Aioli, mayonnaise, curd, anything--this method works!
