Here's a couple of recipes for some favorite liqueurs:
1 1/4 c blended whiskey (or to taste)
1 pint half-and-half cream
1 t vanilla
3 T chocolate syrup
1 c sweetened condensed milk
Combine ingredients until blended. Refrigerate what doesn't get consumed.
1 lb coffee beans, coarsely ground (decaf or regular) I usually try to get a pretty dark roast bean
Soak in 1 1/2 quarts water in a small cooking pot. After it sits for 24 hours, simmer for 20 to 25 minutes. Cool and strain.
3 c brown sugar
2 c white sugar
2 1/2 qts water
Simmer in a larger cooking pot for 60 minutes until thickened. Cool.
Add the coffee to the sugar mixture in the larger pot.
Add 1 fifth everclear (or vodka)
2 oz vanilla (good mexican vanilla, if possible)
Combine and pour into bottles. This usually makes about 5 1/2 Grolsch bottles of Kahlua. Best if you let it age for 2-3 months.
