For a savoury biscuit recipe that calls for tinned tomatoes, choose the tomato form the recipe specifies before choosing a tin size: finely chopped tomatoes give smaller pieces, while standard chopped tomatoes leave more noticeable pieces. A 227g single tin may suit a small quantity; a 400g tin makes more sense when the recipe uses enough or you have a plan for the remainder. Do not swap tinned tomatoes into a recipe calling for sun-dried tomatoes or another tomato form without a tested method that accounts for the liquid.
If your cracker, cheese biscuit or biscotti recipe uses a small amount of chopped tomato, a 227g single tin is worth comparing with a 400g tin. Check that the recipe accepts tomato pieces before choosing by size alone.
Finely chopped tomatoes are relevant when a savoury dough calls for tomato pieces distributed through the mixture. They still contain liquid, so the recipe needs to explain how to handle it.
If you are adapting a savoury biscuit recipe, check whether it calls for tinned tomatoes, sun-dried tomatoes or another form. Tesco Recipes’ savoury biscotti uses sun-dried tomatoes, not tinned tomatoes.
Start with the recipe’s tomato form and preparation method, then match the quantity to a single tin.
| Priority | What to check | Your needs |
|---|---|---|
| Recipe match | Check the named tomato form, amount and instructions for draining, reducing or otherwise preparing it. Tesco Recipes’ savoury biscotti specifies sun-dried tomatoes. | If my recipe calls for sun-dried tomatoes or a dry flavouring, I would not replace them with tinned tomatoes without a tested method. |
| Piece size | Compare finely chopped with standard chopped tomatoes. Mutti describes Polpa as finely chopped pulp in juice; Napolina describes its chopped tomatoes as chunky and in juice. | I want smaller pieces distributed through a savoury dough, or visible tomato pieces if the recipe allows them. |
| Tin size | Compare the recipe quantity with 227g and 400g single tins. Tesco Groceries lists a 227g chopped tin and 400g chopped and finely chopped tins. | For a small batch, I would rather open a tin close to the amount I need. A larger tin works if I can use the rest. |
| Leftovers and label | Check the storage instructions on the tin you buy. Marks & Spencer directs buyers of its 400g chopped tomatoes to transfer opened contents to a non-metallic container, refrigerate and eat within 3 days. | If the recipe uses only part of a tin, I need a practical plan for the remainder and will check the current label for storage and ingredients. |
Opening a larger tin can leave tomatoes unused after a small baking batch. Tesco Groceries and Napolina list 227g chopped-tomato singles as well as 400g formats.
Check the recipe quantity first. If it accepts chopped tomatoes, compare the 227g format before choosing a 400g tin.

This 400g peeled-tomato tin is a conditional choice for a recipe that specifies peeled tomatoes. Check the required quantity and preparation method; for a small batch, plan a use for any remainder.
Do not add them as an automatic substitution. Tinned chopped tomatoes contain juice, and a biscuit recipe needs to specify a suitable tomato form, amount and method. If it names another ingredient, follow that recipe or a tested adaptation.
Choose by the amount and tomato form in your recipe. Tesco Groceries lists a 227g chopped-tomato single and 400g chopped and finely chopped singles. A 400g tin is more practical when the recipe uses enough or you have a plan for the remainder.
