Around 300 grams of leg of lamb - chopped into small pieces.
The usual chunks of frozen pulped garlic, ginger and chillie from your freezer.
2 teaspoons salt.
1 teaspoon haldi (turmeric)
3 teaspoons garam masala
2 teaspoons ground coriander
2 teaspoons ground cumin
2 dessert spoons of plain natural yoghurt
A few dshes of vinegar
2 medium onions - chopped along the grain - long
4 smallish tomatoes - deseeded and chopped relatively finely
4 mediumish white mushrooms - chopped finely
Pinch of cumin seeds
3 bay leaves.
1 mug of Basmati rice.
Anyway - make sure the lamb pieces are chopped small - about the size of a heaped teaspoon each or thereabouts. And now for the action ... Get a glass bowl. In it put the two dessert-spoons of natural yoghurt. Put in all the spices as per the amounts listed above including a few dashes of vinegar - and then stir it all up. (If you, like me, are using chunks of frozen pulped garlic, ginger and chillie - then be sure to defrost the chunks by zapping then for 20 seconds on high power in the microwave first.)
