This is one of my favourite curries. It is from the Goan region and because of the Portuguese influences it is made with either Beef or Pork. It is a hot, spicy curry with a bit of acidity which is added by vinegar.
You could also make it using chicken.
If using pork or beef, see my Curry-Meat Technique by clicking here. You will NOT use this technique if you are making the recipe with chicken
