Thai Sweet Chilli Sauce - cooking recipe

Ingredients

7 fresh red serrano peppers or 7 Thai chiles
4 cloves garlic, peeled
3 tablespoons fish sauce
1 cup rice vinegar
1 cup water
1 cup granulated sugar

Preparation

Remove stems from chillies (leaving seeds in is optional) and place chillies and peeled whole garlic in a mortar and grind into a paste (some pieces of the chillies can remain visible).
Or alternately, you may place in a small spice mill set on pulse.
Combine ground garlic/chilli mixture with fish sauce, rice vinegar, water and sugar in a small saucepan, and whisk together.
Set heat on medium, and bring to a boil.
Reduce heat to low, and cook, stirring, until mixture has thickened and lightly coats the back of a spoon, about 15-20 minutes.
Allow to cool, and store in a sealed container in the refrigerator until used.
