Sugar-free Kecap Manis

Kecap manis or sweet soy sauce is a staple in South-East Asian cooking. It is the backbone of dishes like nasi goreng or char kuay teow. This is a ubiquitous sauce, also known as “ABC sauce” or “Bangso sauce” thanks to the name of some popular brands.

The problem with kecap manis is simply that it contains a huge amount of sugar, which is why I usually make my own. It’s really simple and inexpensive…when I needed to make a fresh batch of kecap manis today I found all the ingredients in my pantry – there was no need to go out and buy more. Of course I realize that I have a really well stocked pantry and herb garden at the moment! There was a little fun in playing around with different aromatics. Today’s batch was really lovely, I think because of the lemongrass and kaffir lime leaf I put in. Of course these are optional extras but I think the sauce was a little more fragrant than the basic one I usually do.

I’ve been a bit disorganized this week. It has been a busy season, and it was not helped by having a last minute talk to prepare for (with 3 days’ notice!). So I had plans to make char siew noodles but because I was so busy pushing out the PowerPoint slides, I forgot to marinate the pork and only got to it at 1 am! And somewhere in the murk of sleepiness I remembered also that I had to make the kecap manis from scratch as it is one of the ingredients for the noodle sauce. Anyway this morning I was much fresher and making the sauce was easy and relaxing.

So here’s the kecap manis recipe. It can probably be kept in the fridge for a few weeks. The recipe makes about 250 ml or 1 cup of sauce. After today’s lunch of char siew noodles (yes, kecap manis is needed for the noodle sauce), I will probably try to use the sauce up in recipes like ayam manis (chicken with sweet soy sauce) and nasi goreng.

  1. Hi! Lovely recipe! One question: Will the sauce harden after cooling down? Since it is using erythritol?
