People making one tomato-based dish
If your recipe uses most of a tin, a single 400g format lets you buy for that dish without committing to a multipack. Decide whether the finished dish needs chilled transport before you leave.
Who is a single tin for?
Cooks choosing a particular texture
Napolina describes its standard chopped tomatoes as chunky and its plum tomatoes as fleshier. Mutti describes its finely chopped tomatoes as having smaller pieces and a more consistent texture. Choose according to the dish, not just the tin size.
Households planning around leftovers
A single tin can fit a one-meal plan, but check what to do with any unused contents. For example, M&S directs buyers to transfer its opened chopped tomatoes to a non-metallic container, refrigerate them and eat them within three days.
What should you check before buying?
Start with the amount your recipe needs, then choose the texture and plan for storage after preparation.
| Priority | What to check | Your needs |
|---|---|---|
| Tin size | Check the recipe quantity and whether a 400g single tin will leave unused tomatoes. Compare the pack format, not just the product name. | I am making one dish and would rather buy one tin than keep extra unopened tins. |
| Tomato texture | Choose standard chopped for visible pieces, finely chopped for smaller pieces, or whole plum tomatoes to crush or blend yourself. None is necessarily a smooth substitute for passata. | Visible tomato pieces suit my dish; for a more even sauce, I would choose smaller pieces or allow time to blend. |
| Picnic transport | Check whether the prepared dish contains food you would normally refrigerate. The Food Standards Agency’s picnic guidance for England, Northern Ireland and Wales advises keeping such food cool, using a cool box or bag with ice or frozen gel packs. | My prepared dish needs to stay cool until it is served, so I need a way to carry it chilled. |
| Opened-tin storage | Read the exact tin’s instructions for transferring, refrigerating and using leftovers. Directions can differ between products. | If the recipe uses only part of the tin, I need a container and a plan for the remainder. |
What can complicate picnic plans?
-
Preparing a dish early without planning to keep it cool
An unopened tin and a prepared picnic dish have different storage needs. The Food Standards Agency advises keeping foods normally refrigerated at home cool on a picnic.
Carry those prepared foods in a cool box or bag with ice or frozen gel packs, keep it shaded and take food out when needed.
-
Assuming every 400g tin gives the same texture
Chunky chopped tomatoes, finely chopped tomatoes and whole plum tomatoes can produce different results or require different amounts of crushing and blending.
Decide on the finished texture before choosing the format, particularly if you will prepare the dish before travelling.
-
Applying one brand’s leftover directions to another
M&S says to refrigerate its opened chopped tomatoes in a non-metallic container and eat them within three days; the Joybuy listing for Napolina Chopped Tomatoes 400g specifies two days.
Follow the current label on the tin you buy, including its container and refrigeration instructions.

Frequently asked questions
Is one 400g tin enough for a picnic dish?
One 400g tin can suit a recipe that uses most of its contents; check the recipe quantity and number of servings before buying. If you use only part of it, follow that tin’s directions for the remainder.
Should I buy chopped, finely chopped or plum tomatoes?
Choose chopped tomatoes when visible pieces suit the dish, finely chopped tomatoes for smaller pieces, or whole plum tomatoes if you want to crush or blend them yourself. Check whether the recipe needs an additional step to reach its intended texture.
How should I carry a prepared tomato dish to a picnic?
If it is a food you would normally refrigerate, keep it cool until serving. The Food Standards Agency’s picnic guidance for England, Northern Ireland and Wales advises using a cool box or bag with ice or frozen gel packs, keeping it shaded and taking cold food out only when needed.
Can unused tomatoes stay in the opened tin?
Follow the particular product’s label rather than assuming all tins have the same directions. M&S says to transfer its opened chopped tomatoes to a non-metallic container, refrigerate and eat within three days; the Joybuy listing for Napolina Chopped Tomatoes 400g also specifies a non-metallic container and refrigeration, but says to use them within two days.
