My mom, actually.

The trick to adding coffee to ice cream is to make a syrup out of leftover coffee (if you have that problem.). It’s not hard- just boil it down… as far as you can, add brown sugar until it starts coating the spoon. Add some butter (which smoothed out some of the harshness).

If you go too far with the syrup…. It might become a caramel. Which. Is also good.
