Oh my it has been a cold week in much of the country—a good reason to stay inside and keep warm with a big pot of hearty soup! Kale is plentiful in the markets these days, mostly because it’s one vegetable that seems to thrive in cold temperatures. Kale and Italian sausage are one of those heavenly combinations, and together with beans, onions, tomatoes, and stock? Truly delicious.
Caramelizing onions, by slowly cooking them in a little olive oil until they are richly browned, is a wonderful way to pull flavor out of the simplest of ingredients. Onions are naturally sweet; and as caramel comes from the simple cooking of sugar, when you slowly cook onions over an extended period of time, the natural sugars in the onions caramelize, making the result intensely and wonderfully flavorful.
