Is there a technique to making Caramel in a Microwave oven?
Microwave candy recipes are very fast and easy. They tend to be only a little different in flavor than the stove top versions in my experience. There seems to be a little less depth of flavor.

The recipes usually call for short periods of microwaving and frequent stirring. As far as the cooking times- I have to follow the recipe as I have no way of measuring the temperature in the microwave.

I personally have had great success with peanut brittle recipes (which get hotter than caramel):

A cursory google search found several recipes for caramel but I have not tried them personally.
