One-person cooks with limited fridge space
If a recipe uses about 227g of tomatoes, a small tin can avoid an opened remainder. Check the recipe amount rather than assuming that every meal for one needs a whole tin.
Who is each tin size for?
People preparing small meals for delivery
Match the tin to the number of portions being cooked and plan how any opened remainder will be stored. An organised delivery operation also needs to protect food from contamination during storage and transport, as GOV.UK's food-business guidance explains.
Two-portion cooks and batch-sauce planners
A 400g tin may fit a recipe that uses the full can. ASDA Groceries and Sainsbury's each describe their researched 400g chopped-tomato tins as two servings; check the recipe and the tin's instructions if you intend to keep any remainder.
What should you check before buying?
Start with the amount of tomato the recipe uses, then check its texture and your plan for anything left in the tin.
| Priority | What to check | Your needs |
|---|---|---|
| Tin size | Compare the recipe amount with 227g and 400g tins. Sainsbury's calls its Napolina 227g tin one serving; ASDA Groceries and Sainsbury's describe their 400g tins as two servings. | I'm cooking one compact meal and would prefer to use the whole tin, or I'm making enough for two portions. |
| Leftovers | Check the opened-tin instructions on the product you buy. Sainsbury's specifies transferring its 400g tomatoes to a non-metallic container, refrigerating them and using them within two days; M&S specifies three days for its 400g product. | Will I have a suitable container and fridge space if the recipe uses only part of a larger tin? |
| Tomato texture | Distinguish chopped tomatoes from finely chopped pulp and plum tomatoes. Napolina describes its chopped tomatoes as chunky, while Mutti describes Polpa as finely cut pulp in juice. | For this sauce, I want to know whether visible tomato pieces suit the dish or whether I should choose a finer format. |
| Delivery handling | For an organised food-delivery operation, check storage and transport arrangements as well as tin size. GOV.UK says food-business packaging or containers must protect food from contamination and be marked for food contact. | If meals are being delivered by an organisation, I need a handling plan that covers the food after the tin is opened. |
What can catch you out?

Choosing 400g when the recipe uses much less
A larger tin can leave opened tomatoes to store after a small meal, even when the full tin would suit a two-portion recipe.
Check the recipe quantity before buying. If it uses only part of a 400g tin, decide when the remainder will be used and follow that product's storage instructions.
-
Assuming every opened tin keeps for the same time
Label instructions differ: Sainsbury's specifies two days after transfer and refrigeration for its 400g chopped tomatoes, while M&S specifies three days for its 400g product.
Read the label on the tin you use. Transfer any unused contents to a suitable non-metallic container and refrigerate them as instructed.
-
Reading texture descriptions as a taste comparison
Napolina's chunky description and Mutti's description of finely cut Polpa explain different product formats; they do not establish which will taste better in a particular meal.
Choose the cut of tomato your recipe calls for, and check the product description if the finished texture matters.
-
Treating a small tin as the whole delivery plan
Using less tomato does not address how an organised service protects prepared food during storage and transport.
For organised meal delivery, check the containers and handling arrangements separately. GOV.UK's food-business guidance calls for packaging or containers that protect food from contamination and are marked for food contact.

Laila Canned Plum Tomatoes 400g
Consider this 400g tin when the recipe calls for plum tomatoes and you can use the full quantity or plan for a remainder. It is not the chopped-tomato format discussed for small sauces; check the recipe before substituting it. If any tomatoes remain, the product guidance calls for transfer to a non-metallic airtight container, refrigeration and use within two days.
Questions about choosing and storing tins
What tin size should I consider for one person?
Start with the amount your recipe uses: a 227g tin is a practical whole-can choice when the recipe calls for roughly that quantity. Sainsbury's describes its Napolina 227g tin as one serving, but that does not mean 227g will fit every dish.
Can I use a 400g tin for a meal for one?
Yes, if the recipe uses 400g or you have a plan for the remainder. ASDA Groceries and Sainsbury's describe their researched 400g chopped-tomato tins as two servings, so check the recipe quantity and the tin's opened-storage instructions.
How should I store unused tomatoes from an opened tin?
Transfer them to a suitable container and refrigerate them, following the specific product label. Sainsbury's instructs users to move its opened 400g chopped tomatoes to a non-metallic container and use them within two days; M&S gives a three-day period for its 400g product. Zero Waste Scotland also advises moving leftovers out of an opened can before refrigeration.
Which tomato format should I choose for a finer sauce texture?
Consider a finely chopped pulp rather than a conventional chunky chopped-tomato format. Mutti describes Polpa as finely cut pulp combined with juice, while Napolina describes its chopped tomatoes as chunky; check the cut your recipe needs.
Does a small tin cover food handling for an organised meal-delivery service?
No. Tin size may help you match a recipe quantity, but an organised operation must also address storage and transport. GOV.UK's food-business guidance says packaging or containers must protect food from contamination and be marked for food contact.
