When the cold weather sets in I naturally turn to warmer food and drink such as soup, stew, broth, and tea. A cold smoothie is just not appealing.
I typically consume elixirs in the winter. However, warm smoothies have become more of a mainstay.
Warm smoothies are really easy to make. Simply warm the liquid a recipe calls for to just under a simmer. Then proceed with making your smoothie as normal. One caveat, you may want to avoid frozen ingredients.
