Peaches and tomatoes are generous with sweetness, but a bowl made only of generous things can feel flat. Pickled onions bring the clean, sharp line that lets you taste the fruit properly.

They need only fifteen minutes in vinegar. Make them first, then toast the bread while they turn pink. The onion liquid becomes part of the dressing, so nothing sharp is wasted.

Ingredients

Makes 4 servings

Quick-pickled onions

Panzanella

Equipment

  • Small jar or bowl with lid
  • Large baking tray
  • Large serving bowl

Method

  1. Pickle the onion

    Put the onion in a jar with the vinegar, sugar and salt. Close and shake, or press everything down in a bowl. Leave for fifteen minutes, turning once. It should become bright pink but still have a little crunch.

  2. Toast the bread

    Heat the oven to 200°C fan. Toss the bread with two tablespoons of oil and bake for eight to ten minutes, turning once, until the crusts are crisp. Cool for five minutes.

  3. Build the dressing

    Lift the onion from its liquid, keeping the liquid. Put the tomatoes in a bowl with the onion vinegar, lemon juice and remaining oil. Leave for five minutes so the tomatoes make the dressing more generous.

  4. Add peaches and bread

    Fold in the peaches and bread. Wait ten minutes, turning once from the base of the bowl. The bread should catch the dressing without losing all its texture.

  5. Finish with the onions

    Add the pickled onions and basil just before serving. Taste for salt; the onion liquid is seasoned, but the bread may need one last pinch.

One small onion brings enough acidity for the whole bowl.

The onion should still crunch

A quick pickle is not meant to turn the onion soft. Thin slices need fifteen minutes; thick slices need longer and can taste raw in the middle. If the onion is very sharp, add another pinch of sugar rather than leaving it in vinegar for hours. If it has gone too soft, use it anyway and reserve the crispest bread for the top. The salad will have more acidity and less bite, but it will still make sense.

Do not warm the pickle jar.

Cider vinegar gives a gentler, fruitier pickle. Rice vinegar works too, though it makes the onion pale and sweet. You can add a strip of lemon peel or a few coriander seeds, but keep the pickle simple if the tomatoes are delicate. The dressing should make you take another bite, not announce itself from across the table.

A useful extra jar

Make double the onions and use them through the week on beans, eggs, sandwiches and roasted vegetables. They are at their brightest after the first day.

Use the pickle with restraint

Pickled onion brings salt, acid and a little sweetness, so it can season the whole bowl before you add any extra vinegar. Start with a small spoonful of the liquid and taste one tomato. Add more only when the fruit tastes dull. Too much pickle liquid makes the bread wet and pushes the peach into a sharp, savoury corner. The onions themselves are best drained for a minute, then scattered through the salad so some pieces stay crisp. A glass jar makes it easy to see whether the slices are covered while they sit. Keep the jar cold, use a clean fork and do not return a piece that has touched the salad. For lunch, pack the onions with the tomatoes and keep the bread separate. At dinner, the ten-minute rest is enough for the bread to catch the juice without losing every crisp edge. Fresh basil or mint at the end helps the vinegar taste cleaner.

Questions

Can I pickle the onions ahead?
Yes. They are ready after fifteen minutes and keep covered in the fridge for two weeks.
Can I skip the sugar?
Yes, although a small amount rounds off the vinegar. Add a pinch only if the onions taste aggressively sharp.
Can I use balsamic vinegar?
You can, but it makes a dark, sweet dressing that hides the peach. Red wine or cider vinegar is better here.
