Buns

I thought of something that my Mom used to have and even I had one when I was first married 35 years ago. It was called a bun warmer and you placed it on the burner with a little bit of water in the bottom and then laid your buns or bread on a little rack and covered it with a domed lid and steamed your buns while your hot dogs or hamburgers were cooking. Do any of you remember those? ( I even think mine was avacado green!)

I remember those. Also, the electric ones. Therem toom was
the kind that had a ceramic tile in the bottom. You'd remove the tile, heat in oven, return it to the basket and cover it with a tea towel.

I still have one. We got it as a free gift with a big set of "waterless cookwear" almost 25 years ago. The whole thing is aluminum, but the bottom is thicker, to control the heat a little better. It has an insert with holes, to allow the steam to circulate. There are two vent holes in the top, that can be opened or closed, depending if you want to steam or crisp. Most of the time nowadays, though, I just wrap buns in wax paper and put them in the microwave on the lowest sitting for about 30 seconds.
Also have a built in food warmer next to my Five Star range that supposedly works well for bun warmning. Never used it for that, though, since it takes a long time to warm up.

Doesn't the new generation of George Foreman grills have a bun warmer on top? Your rolls are warmed why your burgers are cooking.

Any good Mexican restaurant uses something similar to warm the tortillas immediately before serving--you put 'em in the top, pull down a handle that releases steam into the chamber with the tortillas (or buns) and voila! Warm tortillas. However, I would think most people these days would accomplish the task at home in a microwave.
