For a conventional sweet cake, choose the ingredients specified by the recipe rather than a savoury pasta sauce. If you are making an intentional savoury tomato bake, compare salt per 100 g: plain passata offers an unseasoned tomato base, while a ready-made sauce brings herbs and other flavourings that must suit the recipe.
If you are making a conventional sweet cake, check the recipe before buying a tomato product. The pasta sauces described by ASDA Groceries and Sainsbury's are intended for savoury cooking, not as substitutes for sweet-baking ingredients.
If the bake deliberately includes tomato, compare salt per 100 g and decide whether you want a seasoned sauce or a plain base whose seasoning you control.
If a ready-made sauce saves preparation time, check the salt value rather than relying on another front-of-pack claim. Tesco's No Added Sugar Bolognese Pasta Sauce, for example, makes a sugar-related claim, not a reduced-salt claim.
| Concern | What to check | Who this matters to |
|---|---|---|
| Recipe fit | Check whether the recipe calls for a savoury tomato ingredient. For a sweet cake, follow its specified ingredients instead. | If I am making a sweet sponge or loaf, I do not want savoury herbs and onion changing the intended flavour. About 46% of consumers put recipe fit first. |
| Salt content | Compare salt per 100 g, then account for the quantity the recipe uses; serving sizes can differ between packs. | For a savoury bake, I want to know how much salt the tomato ingredient adds before seasoning the rest. Salt content is the primary concern for about 36% of consumers. |
| Ready-made seasoning | Decide whether the recipe needs a seasoned pasta sauce or a plain tomato base that you will flavour yourself. | When I am short of preparation time, a sauce with herbs already added may suit my savoury recipe. Roughly 18% of consumers prioritise that convenience. |
Being tomato-based, low fat or labelled no added sugar does not establish a reduced-salt claim. The checked ready-made sauces list different salt values.
Read salt per 100 g on the pack and use the amount your recipe calls for to assess its contribution to the bake.
The checked sauces are described for pasta and other savoury dishes and contain savoury flavourings. That makes them a poor like-for-like choice for a conventional sweet cake, rather than a food-safety prohibition.
Use pasta sauce only if the recipe deliberately calls for a seasoned tomato element in a savoury bake.
Labels can define a portion as different amounts, so two portion figures need not describe the same quantity of sauce.
Compare salt per 100 g first, then calculate the amount for the quantity going into your recipe.
The checked Napolina passata lists tomatoes and citric acid, whereas the ready-made sauces include flavourings such as herbs, onion or garlic.
For a savoury bake, plan any additional seasoning the recipe needs if you choose passata.
The checked 450 g Low Fat Bolognese is a ready-made sauce for savoury meals.
The checked passata is a smooth tomato base, not a fully seasoned pasta sauce.
The checked 500 g No Added Sugar Bolognese is a seasoned tomato pasta sauce.
The checked tomato-and-herb pasta sauces include a 700 g jar and a 150 g stir-in pot.
The checked 500 g Bolognese Pasta Sauce is presented for savoury dishes including meatballs and lasagne.
The checked 340 g Tomato and Basil Pasta Sauce combines tomato, basil and a soffritto base.
This plain tomato base is relevant if you are making an intentional savoury bake and want to add the recipe's seasoning yourself.

Consider this for a savoury tomato bake when you would rather season a plain base than use a ready-made pasta sauce. The listed ingredients are tomatoes and citric acid, and the listed salt value is 0.12 g per 100 g. It is passata, not a ready-made reduced-salt pasta sauce or a substitute specified for a conventional sweet cake.
A savoury pasta sauce is not a like-for-like ingredient for a conventional sweet cake. The checked products are intended for pasta or other savoury cooking; use one in baking only when the recipe deliberately calls for a seasoned tomato element.
No. Tesco's checked No Added Sugar Bolognese Pasta Sauce lists 0.64 g salt per 100 g. Check the salt entry on the nutrition panel rather than treating a sugar-related claim as a salt claim.
Start with salt per 100 g, then account for the quantity your savoury recipe uses. Serving-size figures may refer to different amounts; ASDA Groceries lists 0.12 g per 100 g for the checked Napolina passata, while the checked ready-made sauces have different formulations and salt values.
No. The UK government's publication Salt reduction: targets for 2024 addresses targets for businesses, not certification of a particular sauce. Check the current jar's label for its salt content and any product-specific claim.
