Hot and sour potato shreds
In Chengdu this is the dish a family orders when the table already has something rich: a heap of potato cut as fine as matchsticks, cooked for barely two minutes so it stays crunchy, sharp with vinegar and warm with dried chilli. Over the border in Shanxi the same dish is made with the province's dark aged vinegar (lǎo chéncù) and less chilli, and it tastes deeper and slightly sweet; both versions are given here. It goes with plain rice and any braised tofu or bean dish. Chef's tip: rinse the cut potato until the water runs clear, because that washed-off starch is what turns the shreds gluey in the wok.
