- Put toothpicks into the grapes, set aside. Line a baking sheet with wax paper or parchment.
- In a small double boiler, melt the chocolate and oil together over medium-low heat, stirring until melted, about 5 minutes (or in the microwave on high power 30 seconds, stirring once). Dip the grapes in the chocolate and then in the toffee. Place on the parchment lined baking sheet. Repeat until all the grapes are used. Chill until set.
