Kahlua - cooking recipe

Ingredients

3 cups sugar
3 cups water
2 cups boiling water
1/2 cup instant coffee
2 tablespoons vanilla extract
1 (750 ml) bottle vodka

Preparation

1. Boil sugar and 3 cups water over medium heat until thick and syrupy. Remove from heat and cool slightly.
2. Combine boiling water, coffee and vanilla. Add to syrup.
3. After the mixture has cooled at least to room temperature add vodka. We store it in vodka bottles and store it in the fridge, although I have never heard of it going bad on the counter.
Note: When I double this recipe I use a half gallon of vodka and just enjoy the extra alcohol content.
