This Indonesian Sambal Bajak is very addictive. In an airtight bottle it keeps for weeks (ha ha) in the fridge. I love it on rice, steaks but best on crackers with a good sharp cheddar. I've tried commercial brands but nothing beats this hot, savoury, nutty home made sambal. A note about the trasi (blachan) - only buy a small amount, it lasts forever and is used only in small amounts.....but it stinks, I keep mine in a ziplock bag in the freezer.
