When I was a kid in Bulgaria (and probably now) you could go to one of those small streetside shops in the winter. Along with cheap tea or coffee, you'd be able to get a cupful of beef or chicken stock to warm you up.

I still have a cup of stock every now and then - half a cube per mug, with a splash of lemon juice, salt and pepper to taste. Wakes and warms you up like anything.
