Aunty Jennifer's Lamb Betawi

Recipe Notes:
To be honest, I am not entirely sure the origin of this dish. My aunt claims she learnt it from an Indonesian lady, but there is nothing on google with Indonesian descent that I could find to prove this is true. So let’s just say.. is not exactly Indonesian, but has an Indonesian influence.
It would go great with rice and any Indonesian vegetable, but if you like to mix things up I recommend trying it with Mallum! Mallum is a coconut based Sri Lankan vegetable dish that (in my opinion) goes excellent with Betawi.
