Fifteen varieties on an August stall, and a question no one asks: since when, exactly? The tomato, which we think of as immutably Mediterranean, is a newcomer—and knowing why some have flavor comes down to a few minutes of biology.
In the markets of Nice, summer is measured by the number of crates of tomatoes. Red, black, yellow, striped, misshapen, calibrated. We buy them on a whim, go home, and half the time we're disappointed without understanding why. Yet everything has an explanation, and a detour through history is worthwhile: it changes the way we choose.
A newcomer mistaken for an ancestor
The tomato has nothing Mediterranean about it. It comes from the Andes, from Peru first, then Mexico, where the Aztecs had been cultivating it for a long time—genetic analyses trace its domestication back about eight thousand years. It arrived at the Spanish court in the 16th century, and the first European plants grew in the gardens of Seville.
After that, France mistrusted it for a long time. The tomato belongs to the nightshade family, like deadly nightshade: it was suspected of being toxic and cultivated for ornament. It was called "love apple" or "golden apple"—the pomodoro that Italians still say. It wasn't until the 18th century that it truly crossed the Italian border and established itself on the coast.
What followed is an episode that the people of Nice should savor. In 1792, the Fédérés from Marseille went to Paris and, wherever they were celebrated, demanded tomatoes—the vegetable had just conquered Provence. They eventually found some for them, at exorbitant prices, and the trend spread north. The word "tomate" itself only entered the dictionary of the French Academy in 1835.
In other words: ratatouille, salade niçoise, and pan-bagnat as we know them are recent inventions. Stuffed vegetables undoubtedly existed before the tomato; Niçoise cuisine adopted it about two and a half centuries ago, and integrated it so quickly that it's now unimaginable without it. That's the hallmark of very good ideas: they make you believe they've always been there.
Why some have flavor and others don't
Here's the point that should be displayed on all stalls. The aroma of a tomato—about four hundred aromatic compounds, very volatile—forms at the very last stage of ripening, on the vine. Not before. A green-picked tomato will eventually redden in the crate, because the color continues to evolve. But it will never produce those aromas. It will be red and silent.
This is the whole difference between a fruit picked for travel and a fruit picked to be eaten. The first must withstand days of transport and shelf life, so it's picked firm and pale. The second is picked ripe, transports poorly, gets bruised, sometimes bursts on its own—and that's exactly why it has flavor.
Second rule, and this one is for your home: never put tomatoes in the refrigerator. Cold destroys these volatile aromas and makes the flesh mealy. A beautiful market tomato placed in the fridge becomes, overnight, a supermarket tomato. Keep it at room temperature, away from direct sunlight, stem-end up, and eat it within a few days.
On the stall, three signs rarely deceive. First, the weight: a tomato should feel heavier than its size suggests. Then, the fragrance, but you need to smell in the right place—not the skin, which tells nothing, but the stem attachment, where the leaf scent is concentrated. Finally, the suppleness: it should yield slightly under the thumb. And if the fruit is irregular, cracked, bumpy: good sign. Calibrated beauty is an indicator of selection for transport, not for taste.
Varieties, and what they are truly for
A common mistake is to choose based on color. The right criterion is the density of the flesh and the amount of water—that's what determines its use.
The Coeur de Boeuf (beefsteak) is the queen of dense flesh: two to three hundred grams, sometimes much more, almost seedless, with a fine flesh that doesn't release water. It often bursts at full maturity, making it difficult to transport and perfect to eat. Raw in thick slices, or hollowed out for stuffing.
The Black Krim, with its dark red skin tinged with green and brown, plays a different card: sweet, melting, almost without acidity. It's a tomato to be eaten on its own, with a drizzle of oil and nothing else—cooking it would be a waste.
The cornue varieties, elongated like peppers, are fleshy and low in juice: these are the best for a coulis or sun-dried tomatoes, because there's little water to evaporate. Cherry and grape tomatoes are for everyday use, aperitifs, and quick sauces. As for the striped and yellow varieties—green zebra, pineapple, Rose de Berne—they mainly bring acidity, surprise, and color to a dish.
The real pleasure in August, by the way, is to take four or five different ones and serve them together, raw, on the same plate. You understand in one bite what no description can convey.
A local vegetable less obvious than it seems
One figure puts things back into perspective: today, the vast majority of French tomatoes grow under glass, and the country's leading producing region is not ours—it's Brittany. Peak season is in June, stalls follow until September, and after autumn most of what is found in France comes from Morocco or Spain.
Which means that a real local tomato, picked ripe from a plot in the hills or the Var plain, is no longer obvious at all: it's a choice, and it's made at farmers' markets rather than at random. The taste of Nice's summer doesn't fall from the sky—someone decided to pick ripe, knowing that half of it would be crushed before evening.
Peak season from June to September. Store at room temperature, never in the refrigerator, and consume within a few days—old varieties have thin skins and don't keep well.
