Mulligatawny is a spicy soup of Anglo-Indian origin.
It's an extremely satisfying word to say, mirroring as it does the stress-pattern of the much-loved refrain have a banana.
Mulligatawny comes in many variations, but basically if you fancy some mulligatawny soup then first make some vegetable soup (perhaps lentil and potato with a bit of turmeric in it), and then make a curry (traditionally a meat one), and then mix the two together, and serve.
Just right for a perishingly cold day - and, given its origin, presumably just what you need on a blazingly hot one, too.
Word To Use Today: mulligatawny. This word came to English in the 1700s from the Tamil milakutanni, from milaku, pepper, plus tanni, water.
