The coconut flavour is not as good. While fresh turmeric will provide the best flavour and colour (not to mention health benefits), if you can’t find it, use 1 teaspoon of dried turmeric instead.

Reduce heat to medium-low; stir in coconut milk, tomato sauce, chile, and remaining 1 teaspoon salt. Simmer, stirring occasionally, until mixture is slightly reduced and thickened, about 10 minutes.
