Now comes a bit more difficult part, thicken it without lumps. My favourite way to do this is by using flour. To thicken this sauce I do this in two steps. In between check whether the sauce has the right thickness already or when the sauce is still too thin after two passes, add a third pass.

  1. Add one swabbed tablespoon flour into a cup;
  2. Add 100 ml (hot) water;
  3. Stir it as much as possible;
  4. Remove any lumps;
  5. Add this mix to the sauce
  6. Stir and warm up the sauce till it boils;

Now your sweet soy sauce is ready!
