  • 1 Large Red bell pepper
  • 2-3 Thai chili peppers (I like to use 2)
  • 10 cloves Garlic
  • ½ cup Water
  • 1 cup Sugar
  • 1.5 teaspoon Salt
  • ¾ cup White vinegar


  • 1.5 tablespoons Tapioca starch
  • 2 tablespoons Water


  • Wash, remove seeds and cut 1 large sized red bell pepper into chunks.
  • Peel and wash 10 cloves of garlic.
  • Next, put 2 Thai chili peppers, 10 peeled garlic cloves, 1 large cut up red bell pepper into the mixing bowl. Pour ½ cup of water and blend it.
  • Blend the mixture until it's little chunks, don't have to be fine and smooth.
  • After that, pour the mixture into a pot and turn on medium high fire until it's boiling. Then, add 1 cup of sugar, 1.5 teaspoon of salt, and ¾ cup of white vinegar. Stir and mix it well.
  • Turn the fire to small and simmer for 10-15 minutes. Then, add tapioca mixture (tapioca starch 1.5 tablespoons and water 2 tablespoons mix well) to thicken the sauce.



Cooking tips for how to make Thai sweet chili sauce:

  • Peel garlic and cut red bell pepper into chunks.
  • Then, put garlic, red bell pepper, water and Thai chilis into a tall container. I like to use a pitcher because the stuff won’t come out when you blend it. But, in the video I used a mixing bowl because it is easy to see.
  • Blend until it has little chunks that don't have to be very fine and smooth.
  • Add sugar, salt, white vinegar and simmer the sauce for 10-15 minutes.
  • I like to use tapioca starch to thicken the sauce because it gives a clear and transparent color. The sauce will be thicker when it cools down. However, you can use cornstarch. It works ok.
  • Since Thai chili is very hot, I only use 2-3 chili peppers. You can add more or less depending on how hot you want the sauce. I like to use two Thai chilis because it is not too hot and has a great spicy flavor.
