Tomatoes: A Buying Guide

Six forms of processed tomato sit on most supermarket shelves, and each does something different to a dish. Most home cooks pick whichever is in the cupboard. This guide covers which one to reach for and why.

Tinned Whole Best texture

Whole peeled tomatoes packed in juice. Less processed than chopped - the cells are more intact, so they break down more slowly and give you more control over final texture.

Use for
Long braises Slow ragu Pizza sauce Shakshuka
Crush by hand before adding for best results. Don't blitz - you lose texture.
Tinned Chopped Everyday workhorse

Pre-diced and packed in juice. The cutting releases more liquid and breaks down the cell walls, so they cook faster and give a more sauce-like result. The most processed of the tinned options - can turn watery if rushed.

Use for
Quick pasta sauces Stews Curries Soup bases
Always reduce properly - underdone chopped tomatoes taste thin and sharp.
Passata Smooth sauce base

Sieved raw tomatoes - no seeds, no skin, no added liquid. Closer to fresh tomato in flavour than tinned. More delicate than tinned whole or chopped, and thinner in consistency until reduced.

Use for
Pizza bases Light pasta sauces Tomato soups Braising liquid
Better than tinned chopped when you want a clean, bright tomato flavour without chunks.
Tomato Purée Concentrated flavour

Cooked and concentrated tomato paste - around 3x the intensity of tinned tomatoes. Used in small quantities as a flavour base rather than a sauce component. Easily burns if added carelessly.

Use for
Deepening sauces Bolognese Soups Marinades
Fry it in oil for 60–90 seconds before adding liquid. This cooks out the raw edge and adds depth.
Tomato Concentrate Intense, use sparingly

Often labelled "double concentrate" - even more reduced than standard purée. A small amount goes a long way. Very easy to over-use and make a dish taste metallic.

Use for
Stock enrichment Slow-cooked meats Umami boost
Treat it like a seasoning. Start with a teaspoon.
Fresh Tomatoes When quality matters

Only worth cooking with when properly ripe - out-of-season fresh tomatoes are often worse than good tinned. At their best in summer. Remove the skins before adding to cooked dishes.

Use for
Salads Bruschetta Summer sauces Roasting
In winter, a good San Marzano tin beats fresh. Use fresh only when it smells like a tomato.
