What can I say about mint and chocolate....except simply fantastic. I love making big batches of these and giving them away as gifts. They are really simple to make and they do not take much time.
I have tried several different recipes and each one is basically the same. I find it helpful when looking on line to find recipes that have reviews. You may have to tweak it to your liking-especially when using peppermint. Remember less is more when using any mint extract. They can be so over powering that a great dish can turn to yuck with just 1/2 teaspoon.
For this recipe I went on www.allrecipes.com. This is a great site. You really can find almost anything food related and most recipes have reviews.
This particular recipe is located at http://allrecipes.com/recipe/peppermint-patties/. You certainly don't have to use this one- there are several to choose from.
I keep these in the refrigerator for up to 2 weeks. Remember they are made with sugar which acts a natural preservative. Since the chocolate is not tempered the chocolate will stay on the softer side. But if kept in the refrigerator it will stay slightly firm and give a nice bite.
Merry Christmas and a Happy New Year
