The British Navy's scurvy-fighting citrus ration was lemon before it switched to lime — the "limey" era came later.
How to select & store
Picking a ripe one
Heavy, fine-grained skin with some give — rock-hard lemons are underripe and stingy with juice. Thin-skinned fruit juices best; knobby thick skin suits zesting and candying.
Storing it
Two days on the counter is pretty; three weeks in the fridge is practical. Sealed in a bag they keep even longer. Ten seconds of microwave or firm palm-rolling doubles the juice yield of a cold lemon.

Eating lemon: what to know
What regular consumption looks like
Lemon is a nutritious everyday fruit, best enjoyed as part of a varied diet. It is a good source of vitamin C (about 53 mg per 100 g), supporting immune function and helping the body absorb iron from plant foods.
Sensible amounts
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Evidence & conditions
As a whole fruit, Lemon contributes fibre, vitamins, and beneficial plant compounds, but it has not been shown to treat or prevent any specific condition — so it is best enjoyed as part of a healthy diet rather than as a remedy.

The lemon is the most-reached-for fruit in professional kitchens, and it’s rarely eaten as fruit at all. It’s infrastructure: the acid that balances fat, “cooks” ceviche, stops cut apples browning, sets jam, and rescues any dish that tastes flat. Salt, fat, heat — and lemon.
A hybrid with a resume
Like most citrus, the lemon is a hybrid (citron × bitter orange) that stabilized somewhere around northeastern India and traveled west with Arab agriculture through Persia, reaching Mediterranean Europe by the early Middle Ages. The Amalfi Coast then spent a millennium perfecting it — Sorrento and Amalfi lemons, huge and low-bitterness, are protected-origin crops that end up in limoncello.
Juice vs. zest — two ingredients
The juice is acid; the zest is perfume. The volatile oil limonene lives in the yellow skin only (the white pith beneath is bitter), which is why lemon zest can make a dessert taste more lemony than juice ever could. Recipes that call for both are using the lemon as two separate ingredients.
The Meyer detour
The Meyer lemon — actually a lemon-mandarin cross brought from China in 1908 — is thinner-skinned, sweeter, and floral enough to eat in slices. Worth seeking out for curds and desserts, though its lower acidity makes it a poor preserving lemon.
