My family has been making these walnuts for years. I do not know if they were "invented" by a family member or gotten out of another resource. I do know they're a big hit around the holidays. I put them in cellophane bags to give as gifts. I suppose you could make it with different nuts or extracts, just never have bothered. You can make this on top of the stove or in the microwave. I've included both methods in the recipe below. Everyone loves these little treats. I always double the recipe below. Enjoy!
