Drain and dry the chickpeas hard. Wet chickpeas steam into a paste; dry ones crisp at the edges, which is the entire point of doing this rather than just spooning them in cold.
- Tahini sauce first: tahini, lemon juice and a pinch of salt, loosened with water a spoonful at a time. It will seize and then come back. Keep going until it pours.
- Drained, dried chickpeas crushed roughly with a fork. Most broken, some whole.
- Hot pan, oil, chickpeas in. Press flat. Four minutes untouched, then turn in sections. Another three.
- Harissa and cumin stirred through for the last minute.
- Into wraps with the tahini sauce and sliced gherkins.
Warm the wraps for twenty seconds a side in the dry pan afterwards. Cold from the packet they crack when you fold them.
