Place the onion, chilli & thyme in a pot and cooked for 5mins in a little oil until soft but not coloured.
Add the figs, vinegar, sugar & lemon & water, bring to the boil and simmer for 45mins, stirring occasionally. Add a drop of more water, if necessary, until the figs are well soaked.
Leave to settle and soak for 1hour.
Blend in a food processer until smooth( or leave it chunky if you prefer!).
