I first learnt this dish from my maternal aunt who had learnt it from her mother in law. It’s very hot but not in your mouth hot. The heat gets to you from the inside. Very visceral and if you follow the traditional Eurasian recipe, you will then put in all the leftover viscera into the dish.
What makes this different from the usual Southeast Asian curries is the liberal use of mustard seeds in the rempah (spice paste). And what makes this special in this region is also that it’s a dish the Eurasian usually cook for Christmas. And since my aunt had learnt it form her mother in law who grew up in a Christian family then, this makes it the most authentic recipe I can get from a family member.
The seasoning which makes this dish different is vinegar! Yes! Distilled white vinegar. I used about 10 tablespoons in total after constantly tasting till I get the right balance. Salt and sugar of course too.
