When it's cold outside, it's nice to get the stove going and cook onions in beef broth and then add a shot of sherry. (Recipe courtesy my sis!) The whole house warms right up.
Then I top it with a slice of toasted, crusty bread and some cheese and melt it under the broiler using my mum's old onion soup bowls. Now we're warm on the inside too! It somehow makes winter that much more bearable.
