Citrus limon

A tier

Citrus limon is the lemon species—acid yellow fruit with fragrant peel oil used as the default souring and aromatising citrus in global kitchens. Juice provides clean citric acid; zest carries limonene-bright perfume. Cultivars differ in peel thickness, seediness, and year-round cropping. Juice, zest, preserve as slices or confit, and cure proteins lightly. Species-level lemon is the bartender’s and saucier’s everyday acid. Roll before juicing to maximise yield.
