Homemade Thai Sweet Chilli Sauce

Making your own sweet chilli sauce means you can tailor the heat to your own preferences. Use more or less hot birdseye chillies and remove the seeds or leave them in if you like it hot. Keep in an airtight jar in the fridge for up to three weeks.

Picked a basket of Thai chillis yesterday & made this in about 20mins today – sensational. Doubled the recipe & froze half. Next time I’ll make a bigger batch – so easy, looks great, tastes sensational.

Perfect and easy

I tested this recipe, following it scrupulously.

At first it seemed to me that the amount of sugar was very important.

However, the amount of peppers provides a perfect balance between spiciness and sweetness.

Quick recipe, perfect for dips, or to dress salad, spring rolls etc…

A delight, I highly recommend.

I also tested with the juice of half a lime. Excellent !
