Spring in a leaf — free, fleeting, glorious.
For six weeks in spring, Scottish woodlands turn into a garlic-scented carpet. Ramsons. Bear's leek. Whatever you call it, wild garlic is the finest free ingredient in the country. Pesto, butter, folded into scrambled eggs, wrapped around a bit of fish — do everything with it while it's here, because it's gone by June.
Damp deciduous woodland, near streams. Smell first — if it doesn't reek of garlic, don't pick it. Confusion with lily of the valley (poisonous) is possible.
