1 14 ounce can coconut milk
1 tablespoon yellow curry paste
2-1/2 tablespoons fish sauce
1 tablespoon sugar
Combine the coconut milk, curry paste, fish sauce, and sugar in a saucepan and bring it to a boil. Reduce the heat and simmer for about 10 minutes until the sauce thickens.
NOTE:
Yellow curry paste and fish sauce can be found in most supermarkets and gourmet food shops, as well as in an Asian market if you live near a city. This sauce can be made hotter by adding more of the prepared paste. Start off easy, adding more as you go. The sauce gets its beautiful yellow color from the turmeric in the paste.
