Relax and deseed the dried chillies while watching television whenever you can.
Wash the dried chillies and leave them to soak in a pot ready for boiling.
Put the soaked dried chillies to boil. Bring to boil and turn heat on low for an hour.
Meanwhile remove the seeds from your fresh chillies.
Toast your belacan.
Add your oil to wok and start to heat.
Blend your dried chillies and add to your hot oil. Do the same to your fresh chillies.
Fry for half hour till the chillies and oil separates and slowly add in your toasted belacan. (adding more or less is up to you)
TASTE - Add in sugar, more sugar if too spicy
TASTE - To draw out the taste of everything you really need to add some salt (I know belacan is salty; use the best belacan you can get, they are not too salty)
TASTE - Add in your vinegar and NO you cannot really taste the vinegar much. Adjust to your taste.
