A crockpot curry

My week started out well. Joe is in Sydney so on Monday I cooked up an Achar Gosht Keema for Kate and Jenny. That's curried mince in plain English.  I got a packet of Achar Gosht masala (curry powder) from an Indian shop and tipped the whole of it into 500g of semi-fatty mince plus a can of tomatoes and some celery.  And the result was quite tasty.  We had it with rice, raita and chutney.  You need a bit of fat in a curry to carry the flavour.
