Re the frozen White Castles:
I've had them, and they certainly fill the bill when you have the craving and don't live near the real thing, but I found I wanted to "finesse" them to get past their inherent lacking. My method from several years ago:
Slit the cellophane and microwave a pair (or two pairs) for [whatever number of] seconds, then turn them over and give them another zap. I don't remember if they tell you to turn them over. If not, use less time prescribed on each side so you don't totally nuke them. But the turning, at least in my microwave, gave a more even warmth and prevented any cold spots from remaining.
Remove and add a sandwich- or burger-type slice of thin (dill, I think) pickle to each. Now give just a tiny squirt of mustard or ketchup or both, depending on yer preferences, and get them up to your mouth while they're still hot.
What I don't recall from years ago is how they were served if you didn't specify mustard or ketchup. I think it used to be different in different regions. Because of the moistness, I can enjoy them without, or with a little something. It doesn't matter, they're going to slide down just as quickly and easily either way.
