[updated to add the recipe]
Need a quick and easy party appetizer? Use a toothpick to dip big, red grapes halfway into melted white chocolate. Then dip the bottom in crushed nuts (peanuts, cashews, whatever you have). Done, that's it. They taste just like caramel apples. Make a ton because they disappear quickly!
You can totally "wing it" making these, but here is a recipe if you prefer to follow one:
1 lb grapes (any color, the plumper the better)
2 cups white chocolate
1 cup nuts, chopped
Place wax paper on counter. Clean and dry grapes. Remove from stem. Microwave the white chocolate in a shallow bowl in 30 second increments*, stirring each time until melted. Put chopped nuts in a shallow bowl.
Stand the grape on its end, then stick a toothpick straight down the center (it's helpful to stand the grape first, otherwise if it rests at an angle all your toothpicks will be pointing in different directions instead of straight up). Using the toothpick, dip the grape half way in the white chocolate, then dip the bottom in nuts. Stand on wax paper to harden. Refrigerate until ready to serve.
*If any water gets into the chocolate (from the bowl, your spoon, etc.) it will stiffen. Add 1 tsp shortening to make the consistency smooth again.
