I didn't know if it would work, but I wanted a rum and eggnog and I didn't want to have a cold drink (its -9C here, we are so not used to this. Not complaining though). I use Light eggnog because I found the fullfat stuff totally cloying. Simply heat a serving in a saucepan, whipping it violently to get a good head of foam. pour a shot of rum in a glass, add warm eggnog, reserving foam for last. Top with nutmeg.
This was all the cooking I did yesterday (besides work). I had Subway for dinner!
