Only had Bacardi Carta Blanca in the house, but this sounded so good that I wanted to give it a whirl anyway. And it’s delicious! With the Carta Blanca substitution, the Kahlúa becomes very front and center, but the other flavors aren’t totally lost. I’ll make the modified version again, but with 1/4 oz. Kahlúa instead of 1/2 oz.
Found this very interesting. As written it is great. The port does seem to overpower the other ingredients, but not in a bad way. The other ingredients add to the overall taste. I would have again, but may cut back on the port so the other flavours will shine through bettter.
