What is a lemon?
The yellow lemon is a citrus fruit with a thick, bright yellow rind, often oval or slightly rounded in shape. Its juicy pulp is renowned for its tangy, refreshing taste, making it an essential ingredient in many recipes. Its aromas come mainly from the essential oils concentrated in its zest, while its juice, rich in organic acids, gives it a characteristic tangy flavor.
Where does the lemon come from?
The yellow lemon is native to Asia, more precisely to the region between northeast India and Burma. Trade routes and explorers gradually introduced it throughout the Mediterranean basin, where it found a warm, sunny climate conducive to its development. Today, major producers such as Italy, Spain and certain French regions, such as southern Corsica and the Côte d'Azur, grow this citrus fruit all year round. Its worldwide success is due to its many uses, in cooking, health and cosmetics.
What does it look like?
The lemon peel is firm and thick, varying in color from pale to bright yellow. Beneath this rind lies a thin white layer, called ziste, which protects the fleshy wedges and their acidic juice. Each quarter contains more or less seeds, depending on the variety. When perfectly ripe, lemons are juicy, instantly releasing their tangy flavors when squeezed.
