Cooks preparing dishes ahead
If you are making a tomato sauce, dip, stew or pasta dish before travelling, match the number of tins to the recipe and plan how you will store any unused contents after opening.
Who is buying for a picnic?
Multipack buyers planning several batches
Four 400g tins provide 1.6kg in separate portions. A larger case is more relevant if you regularly use the same tomato format and have cupboard space for the remaining tins.
Cooks choosing by texture
Napolina describes its chopped tomatoes as chunky, while Mutti describes Polpa as finely cut pulp with juice. Check which form your planned sauce or dip calls for rather than choosing by brand alone.
What should you check?
Start with the quantity your recipes require, then check the tomato form and what you will do with an opened tin.
| Priority | What to check | Your needs |
|---|---|---|
| Pack quantity | Compare the tin count and net quantity: 4 x 400g is 1.6kg, while 12 x 400g is 4.8kg. Check cupboard space and how often you will use the remaining tins. | I am making a few picnic dishes and want separate tins I can open as needed. A larger case suits me only if I will use the rest in later cooking. |
| Tomato form | Read whether the product is chopped, finely chopped or peeled plum. Napolina describes its chopped tomatoes as chunky; Mutti describes Polpa as finely cut pulp with juice. | Visible tomato pieces matter for my dish, or I would rather start with a more even base. If the recipe needs chopped tomatoes, I should not mistake whole peeled plum tomatoes for the same format. |
| Ingredients | Compare the label for tomato juice, citric acid and added salt. ASDA lists tomatoes, concentrated tomato juice and citric acid for its 4-pack; Mutti lists tomatoes and salt for its finely chopped 4-pack. | I want to know what is already in the tin before seasoning a dip or sauce. |
| Opened-tin storage | Follow the individual label for transferring, covering and refrigerating unused tomatoes. ASDA specifies a suitable non-metallic container and use within four days; Napolina specifies use within two days for its checked 4-pack. | If a recipe uses only part of a tin, I need a container and enough time to use the refrigerated remainder within that product’s stated period. |
What is easy to overlook?
-
Buying a case for a single picnic
A 12-tin case leaves considerably more unopened stock than a 4-pack after one cooking session.
Work out the quantity your recipes use, then choose a case only if the remaining tins fit your cupboard and future cooking plans.
The larger pack also commits cupboard space to one tomato format.
-
Treating every tomato cut as interchangeable
Napolina describes its chopped tomatoes as chunky; Mutti describes Polpa as finely cut. Mutti’s checked 4-pack also lists salt among its ingredients.
Check the cut and ingredient list against your recipe, especially if you want visible pieces or intend to add seasoning yourself.
-
Leaving unused tomatoes in an opened tin
The checked ASDA, Napolina and Sainsbury’s product instructions call for transferring unused contents and refrigerating them. Their stated periods after opening differ.
Have a suitable container ready and follow the instructions on the tin you open. Plan the picnic dish and any leftover ingredients separately.

Common questions
What pack size makes sense for picnic cooking?
A 4 x 400g pack provides 1.6kg across four tins and is a useful starting point if you are preparing several dishes. Choose a 12- or 24-tin case when you expect to use the same tomato format repeatedly and have room to store the unopened tins.
Should I choose chopped or finely chopped tomatoes?
Choose by the texture your recipe calls for: Napolina describes its chopped product as chunky, while Mutti describes Polpa as finely cut pulp with juice. Peeled plum tomatoes are another option if you intend to break them down during cooking.
How should I store tomatoes left over from an opened tin?
Transfer unused tomatoes to a suitable container, cover and refrigerate them, following the specific product label. The checked Napolina 4-pack says to use opened contents within two days, while ASDA’s checked 4-pack specifies a suitable non-metallic container and use within four days.
Can tinned tomatoes count towards 5 A Day?
NHS guidance says 80g of canned fruit or vegetables counts as one 5 A Day portion. It advises choosing canned produce in water or natural juice with no added sugar or salt, so check the particular tomato product’s ingredients.
