Flour is an indispensable ingredient when thickening sauces. There are three kinds of flour that you can use: corn flour, all-purpose flour, and arrowroot.

However, please note that the all-purpose flour is not as thick as the cornstarch and arrowroot. So, if choosing to use this flour, you should use double the amount compared to corn flour.

If the curry sauce is still watery after adding the liquid in, just repeat this step until it reaches the thickness level that you want. Otherwise, if the sauce becomes too thick, add some water to thin it.
