RE: Burgers from the Freezer
Frozen White Castles are o.k. prepared in a microwave. You have to experiment with different heating times and methods (wrapping in paper towels, etc.) to get close to the fresh ones. I always add mustard and a dill pickle slice after removing them from the microwave. They're better than not having any "gut bombs" at all. I do the same thing with Krystals. A friend brings me two or three dozen Krystals, I freeze them, and prepare them the same way.
Hope this helps,
