Mulligatawny

Ever seen the dish 'Mulligatawny soup' when you go to restaurant and see the menu?

Pronounce it carefully and see how it sounds like the tamil words "Malliga(i) Thanni" (Corriander water)

CORRECTION

My friend Manjunath says that it's derived from "Milagu Thanni" (Pepper water).
It makes more sense to me.
