Students preparing several lunches
If you’re cooking a sauce, chilli or casserole for several meals, the number of tins matters just as much as the total quantity: it determines what you’ll need to store after opening each one.
If you’re preparing several lunches at different times, a multipack of separate tins is usually the better choice: you only open as much as you need for each meal. An 800 g tin works well if you’re cooking several portions at once and can refrigerate the leftovers; for a single dish, a smaller size can help you avoid having any left over. In every case, compare the stated weights and check the ingredients and storage instructions after opening.
If you’re cooking a sauce, chilli or casserole for several meals, the number of tins matters just as much as the total quantity: it determines what you’ll need to store after opening each one.
If you can’t easily keep an opened portion chilled, separate tins or a smaller size let you open only what you plan to cook.
If salt, other ingredients, organic certification or stated origin matter to you, compare the labels on the specific products and sizes rather than relying on the brand alone.
First, decide how many meals you’ll prepare each time you open a tin. Then check the stated weight of each tin, how the contents can be stored and the ingredients in the size you’re considering.
| What to consider | What to check | Who it matters to |
|---|---|---|
| Quantity and leftovers | Compare the number of tins and distinguish between net weight and net drained weight. Check the storage instructions for after opening. | If I’m preparing lunches for different days, I’d rather open one tin at a time than keep the rest of a large tin. Around 46% of shoppers would put managing quantities first. |
| Size availability | Check that the multipack or size you want is available at the shop or online grocery service you use. | If I need to cook soon, I want to be able to find a pack size that suits the meal I have planned. Availability would be the top priority for around 27% of shoppers. |
| Ingredients and recipe | Read the ingredients for the exact size and, if they matter to you, check its organic and origin claims. | For a particular recipe, I want to know whether the tin contains tomato juice or purée, salt or an acidity regulator. Around 27% of shoppers would put the ingredients first. |
Opening two separate 400 g tins won’t leave you with the same leftovers as opening a single 800 g tin, even though the total quantity is identical.
If you’re cooking meals several days apart, check how many tins are in the multipack. Save the large tin for meals where you’ll use the contents all at once or can keep the leftovers chilled.
Storage times vary by product: Auchan says to use the contents of its 480 g tin within 2 days, while Jardin BiO étic gives 3 days for its 800 g tin.
Follow the instructions on your product. For the Auchan product, transfer any leftovers to an airtight container and refrigerate them.
