A balance of heat and flavour, with tomato and sugar adding a sweet fruitiness. Warning: a bottle of For, Dou’s unbearably hot sister sauce, recently exploded after two weeks in our fridge. Good with fish. £5, Vinngoute food stall, 5pm-midnight at Street Feast market, Hackney Downs Studios, E5, on Oct 5. vinn-goute.co.uk
