Tomatoes

Ripeness is a smell, not a colour

Tomatoes can turn red before they develop much aroma. That is why a supermarket tomato sometimes looks ready and tastes like wet paper. Hold it near your nose, especially at the stem. If there is no smell, it may improve on the counter, but it will not become a great summer tomato by force of optimism.

There is no clever trick here, only a small piece of shopping judgement: smell the fruit before you fill the basket, then turn it in your hand and look at the shoulder, the base and any bruised points. A tomato that smells good but has a split base needs using first. A tomato that looks flawless but has no scent can still work in a roast, yet it will not suddenly become fragrant in a cold salad. The shop is where you make that decision, not the chopping board.

Weight helps too. A heavy tomato has more juice and usually a fuller interior. That is useful for chopping over toast, though a very juicy fruit can make a pan sauce take longer to reduce. For a salad I want a little give and a strong smell. For roasting I am happy with firmer fruit because the oven will do the softening. Weight also tells you how much water you may be bringing into the pan. A dense fruit can be cut and cooked quickly; a loose, heavy fruit may need a wide tray or a longer reduction. I do not treat either as a fault. I use the dense ones raw and the juicy ones where their liquid has somewhere useful to go.

Why the fridge is usually the wrong place

Cold storage slows the aroma compounds that make a ripe tomato taste like itself. It also changes the texture. The flesh becomes softer in an unpleasant, cottony way, especially after the tomato comes back to room temperature. A cool pantry is fine, but a cold shelf is not a quality upgrade.

There is one practical exception. Once a tomato is cut, the fridge wins because it slows spoilage. Put the cut side against the base of a small container, cover it, and use it soon. Do not leave half a tomato uncovered beside an onion for three days; it will pick up the onion smell and lose the clean acidity you wanted. I keep cut tomatoes away from uncovered dairy and strong leftovers for the same reason. The flesh absorbs nearby smells quickly, and a tomato that should taste of summer can end up tasting of the fridge. Bring it out ten minutes before serving if you are using it raw. Cold dulls the aroma, while a little time on the counter lets the acidity and sweetness show again.

Raw, roasted or reduced

Fresh tomatoes have three useful jobs. Raw, they bring juice and lift. Roasted, they lose water and gain sweetness at the edges. Reduced in a wide pan, they become a sauce, but only after the water has somewhere to go. A narrow saucepan with a lid will steam them rather than concentrate them.

Salt timing changes the result. Salt a salad just before eating when you want pieces to keep their shape. Salt a sauce early when you want the juices to leave and season the whole pan. The same fruit can therefore be crisp at lunch and soft in a pasta sauce at dinner. I salt chopped tomatoes at the table when the pieces are going onto toast, because the bread can catch the juice and the fruit should still look like fruit. In a sauce I salt with the onion or the first tomato addition, then taste again after reduction. That way the salt travels through the liquid instead of sitting on the surface. The method is the same tomato; the timing decides whether the result is a clean piece or a seasoned base.

For the difference between fresh and tinned fruit, read fresh tomatoes vs tinned tomatoes. The buying details are in how to choose ripe tomatoes, and the storage version is how to keep tomatoes fresh. I use those guides alongside the recipes rather than pretending one tomato behaves the same in every pan.
