This is not a Thai curry. I'd say it is more Indian in smell & taste than anything else. There are quite a few ingredients & I think I remember being able to get the Indian spices in Thailand - if not, apologies
Despite the large number of ingredients it's really easy to make - just bung everything together and cook - and it tastes & smells lovely!
OK, for the ingredients:
500g beef cubed.
1/4 tsp turmeric, 2tsp garam masala, 2tsp ground cumin
400g chopped tomatoes. This is obviously canned, but skinned fresh work really well
