Duo jiaoFermented chopped chillies
In late summer, Hunan kitchens ring with the thud of two cleavers chopping heaps of red chillies, the sound of duo jiao (chopped chilli) being made for the year. Chillies, garlic and ginger are chopped coarse, salted heavily and packed into jars to ferment for about a week, until the heat turns rounder, slightly sour and fruity. Spread thickly over steamed fish fillets, stirred into stir-fried pork or eggs, or spooned over steamed taro, it brings colour as much as fire. Common mistake: chopping it to a smooth paste in a blender; the texture should be rough, pieces the size of rice grains, so pulse briefly or use a knife. Normal ferment signs are a few bubbles, a sour smell and a little liquid rising; a fuzzy coloured mould or a rotten smell means discard. It is ready after 5–7 days at cool room temperature, when it tastes tangy rather than raw. Because it contains garlic and ginger and is a low-sugar paste, it then lives in the fridge for up to 3 months, or in the freezer for a year. Chef's tip: wear gloves and open a window; a kilo of chopped chillies is fierce.
