What is kecap manis
Kecap manis is the most widely used soy based sauce in Indonesian cuisine.
Proper kecap manis is usually small batch and producers take great pride and care in making this sweet, salty, rich and molasses-like condiment.
Unlike plain soy sauce kecap manis has a thick syrupy consistency. This is because it's traditionally made by cooking down palm sugar and soy sauce together over low heat until thickened.
Why make your own
It's extremely simple and rewarding making your own kecap manis from scratch.
Not only will it taste much better than mass-produced, store-bought versions but, you will also save a ton of money by not buying something overpriced.
Kecap manis can be extremely hard to come by in some parts of the world including many European countries and large parts of America.
By making your own you will be able to use it freely in any recipe that calls for it. Like my chocolate bbq sauce or a classic Indonesian dishes like nasi goreng.
How does it taste
Authentic kecap manis should be well balanced between salty and sweet.
It should have a smooth syrupy yet still pourable consistency and be without sugar lumps.
The flavour should be complex with a rich molasses flavour coming through.
All the characteristics are achieved by using the correct ingredients and cooking the sauce properly.
Ingredients needed
It only takes a few ingredients to make so make sure the most important ones like soy sauce and sugar are good quality.
- Soy sauce - I used homemade soy sauce I made by growing koji on grains and pulses and then fermented it for about a year. You don't have to do all that)) Simply use a good naturally brewed store-bought version of soy sauce. It will say it on the bottle. I know Kikkoman(affiliate link) has a good natural one. So, go with that.
- Molasses - I use molasses in my kecap manis recipe because I have a hard time finding proper palm sugar. Unless you live in South East Asia, you won't find the proper palm sugar at the proper price either. So, do what I did. The added pure molasses is a great substitute.
- Brown sugar - To boost the molasses notes and make the sauce a bit more nuanced, I use brown sugar. You can easily use regular white sugar instead. The molasses and caramel notes will just be more subtle that way.
- Water - Clean drinkable water will do. As always.
How to make it
I was considering involving the temperature probe in this one but then decided to make it bare basic and not go down the technical route on this one, and just make it nice and easy, short and simple. It's what we all want.
- Get all your ingredients in a sauce pan. Give it a little get-to-know-each-other stir.
- Place the pan on the stove or induction and very slowly start simmering. Give it a gentle stir every minute until the total weight of the sauce has reduced to 220g. A reduction of 31% from its initial 320g combined tarting weight. While the sauce is reducing keep an eye on it so it does not boil over or cook too fast. Low and slow does the magic here.
- Once the correct weight is achieved, let the sauce cool down and then store in airtight containers in the fridge. You now have yourself the perfect substitute for real Indonesian kecap manis.
How to use it
Use kecap manis in any recipe that specifically calls for it or simply use where you would normally have to add soy sauce and sugar separately. Below are a few more ideas.
- Stir fry - A finishing touch to any quick stir fry like this quick duck breast stir fry or add last minute when you make fried rice.
- BBQ - When barbecuing meats like pork belly or alternative steak cuts like bavette, brush it with some kecap manis and give it a few final turns so the sauce can caramelise a bit.
- Dipping sauce - With fresh vegetable crudités, a simple piece of sushi or sashimi, and great with roasted or steamed broccoli or bok choy.
- Glazing - Glaze seared salmon fillet and finish under the grill or use this glaze instead of sweet miso in this baked eggplant dish.
- Curries or stews - Add a final touch of balance and umami to Asian dishes like this Filipino beef adobo, this Thai massaman curry or this Indian coconut chicken curry.

Recipe
Homemade Kecap Manis Recipe (Indonesian Sweet Soy Sauce)
Ingredients
- 150 g (⅔ cups) brown sugar
- 100 g (3/7 cups) water
- 50 g (⅕ cups) soy sauce
- 20 g (1 tablespoon) molasses
Instructions
- Get all your ingredients in a sauce pan. Give it a little get-to-know-each-other stir.
- Place the pan on the stove or induction and very slowly start simmering. Give it a gentle stir every minute until the total weight of the sauce has reduced to 220g. A reduction of 31% from its initial 320g combined starting weight.
- While the sauce is reducing keep an eye on it so it does not boil over or cook too fast. Low and slow does the magic here.
- Once the correct weight is achieved, let the sauce cool down and then store in airtight containers in the fridge. You now have yourself the perfect substitute for real Indonesian kecap manis.
Notes
- You can use regular sugar if you don't have brown sugar but molasses is essential.
- Molasses and barley malt are not the same thing.
- Do not stir the sauce vigorously while reducing.
- Add a teaspoon of liquid glucose if you are worried about the sugar crystalising.
- Store in the fridge sealed airtight. Will keep it for an indefinite amount of time because of the salt and sugar content.
- No need to freeze.
- Use as a glaze when grilling meat, vegetables or fish.
- Add to stews, stir fry, curry and many more dishes as a flavour enhancer.

Where I live this stuff is impossible to find. I love cooking with it as I lived in Indonesia for several years and really like the cuisine. Thanks for sharing this recipe! It tastes exactly the same as the real thing. Never knew it was this easy to make)))))
Charlé
Glad to help Gavin! I live in Russia and had the same problem) Needed a kecap manis replacement fast and this ended up being exactly like the original Indonesian version.
Peter
Live in Russia as well!
Have not come across Melasses though! What's the Russian for it?
Charlé Visser
Сусла/susla. Used to make kvass and Borodinsky bread
Gordon Barnett
For the liquids, why not show the measurements in fluid ounces as well as grams? For the volume measurement in grams, why not show it in ounces?
Charlé Visser
Grams is the future, been the past for many decades in the kitchen. All the other stuff.... not so much. Maybe a casual teaspoon here and there but that's it. All about accuracy and being easy to deal with.
Katie
How long would it keep and do I need to store it in the fridge?
Charlé Visser
It lasts for months and you can simply store in a cool dry place sealed airtight.
