Sweet Chilli Sauce

With the red chilli hot and cherry bomb chillies we decided to make some sauce - we started with 630g of chilli flesh (deseeded) so used 4 cups vinegar, 4 cloves garlic, 4 cups (!) of sugar based on scaling up the recipe. 

Was some of the chillies - probably about 75% of the total. We halved and de-seeded them carefully, chopped the chillies in the magimix with 1 cup of vinegar and garlic and boiled for a while:

Then stored it all in jars - made just shy of 1.5 l of sauce:

Turns out though it stayed runny - is very tasty but did not set. Suspect that the pith of the chillies around the seeds contains the pectin, so carefully deseeding was something of a mistake. Next time...
