Bidayuh Sambal Belachan differs a lot from the Malays version of Sambal Belachan. The most basic of Bidayuh Sambal Belachan consists of anchovies, belachan and bird's eyes chillies only.
All ingredients above (except onion and shallots) shall be pounded roughly together.
The sambal belachan is very nice to be eaten with fresh vegetables such as cucumber, salads and other 'ulam-ulaman'..
To make a good sambal belachan, anchovies shall be pounded first, followed by chillies and belachan consecutively. To avoid overwhelming of belachan, start with a small quantity first.
