When we were little, my sister and I would heat up lemonade in a saucepan. It holds no interest now, but boy, did we love it on a cold day. Then someone came up with Russian Tea. That concoction was divine.
Today, the standard choice after stepping in from the cold is a mug of tea with lemon or milk. If it is a special occasion, a cup of mulled wine is a wonderful way to warm up and relax with friends.
@Dr_Dredd I’ve read about drinkable chocolate, but have never had the opportunity. Where does one find it?
