They are the best candy molds I have ever used, and I have looked all over for my own candy molds, as these live at my mom's house! They are thick rubber, and make the most beautiful candies. I have looked everywhere, and all I find are cheap plastic molds! I have made these before at my house and rolled the individual mints into balls. It could also be rolled out and cut with tiny cookie cutters.
Butter Mint Recipe
1/2 stick unsalted butter cut into slices, at room temperature
1 pound confectioners sugar (about 4 cups)
1 tablespoon plus 2 teaspoons cold water
1/2 teaspoon peppermint extract
Food coloring
In a large bowl, cut butter into sugar. Add 1 tablespoon water, and peppermint oil, and toss with a fork. Press mixture into a ball; if it seems crumbly, add more water, 1 teaspoon at a time, until dough presses together easily. Turn dough out onto a work surface and knead until it's smooth and satiny, 3 to 4 minutes. Press into candy molds. Chill candy molds in freezer for an hour before popping mints out.
Store in the freezer.
