As with lemon juice, the more sorrel you use, the more it has to be balanced with something sweet, starchy or creamy - it's a yin-yang approach to cooking that I find rather calming.
I keep returning to the combination of artichoke, broad beans and lemon. The freshness of young beans and the lemon juice 'lifts' the artichoke and balances its hearty nature.
One Indian-inspired favourite of mine is mashed potato mixed with lemon juice, breadcrumbs, coriander and chilli, shaped into patties, fried and served with chutney and yoghurt.
I have been cooking with preserved lemon for years, using it left, right and centre, but I am still far from reaching my limit.
Jerusalem artichokes have a great affinity with nuts. I love them with chopped walnuts or almonds, lemon juice, garlic, herbs and plenty of olive oil.
