Hosts making buffet fillings
If the tuna is going into sandwiches, wraps or a dressed bowl, the amount left after draining and the packing liquid both affect your recipe planning.
Who is choosing a tin?
Hosts preparing food in a hurry
Less draining can simplify assembly. John West describes its No Drain tuna as ready to use without draining, though the identified examples are multipacks rather than individually sold tins.
Shoppers checking seafood sourcing
If certification or fishing method guides your choice, look for the claim on the exact tin. A statement about one product or an own-label range does not identify the credentials of every tuna tin from that brand or retailer.
What matters when buying?
For a single-tin buffet dish, establish how much drained tuna you need, then choose a packing liquid and pack format that suit the recipe.
| Concern | What to check | Who this matters to |
|---|---|---|
| Usable tuna | Compare drained weight when the liquid will be discarded. The Princes 145g brine tin lists 102g drained weight. | If my filling needs a particular amount of tuna, the weight on the front of the tin alone will not settle how many tins to use. About 29% of consumers put usable yield first. |
| Liquid and preparation | Choose brine, spring water or oil to suit the dish; check whether a product is explicitly labelled no-drain. | When I am mixing tuna with a dressing or assembling food quickly, the liquid and draining step shape my choice. Recipe fit and preparation are the primary concern for about 29% of consumers. |
| Pack quantity | Confirm that the listing is for one tin rather than a multipack, particularly for no-drain products. | If the buffet needs only a small batch, I would rather buy an individual tin than be left with unwanted extras. Avoiding surplus tins comes first for about 21% of consumers. |
| Sourcing details | Look for an MSC label or a specific fishing-method statement on the exact product. | When seafood sourcing determines which tin I pick, I need a claim tied to that product rather than the brand as a whole. About 21% of consumers make sourcing credentials their primary concern. |
Mistakes to avoid
-
Planning portions from the front-of-pack weight
Some of that weight is liquid: the Princes Tuna Chunks in Brine tin is 145g but lists 102g drained weight.
When your recipe specifies drained tuna, calculate the quantity from the drained weight on the exact tin.
-
Keeping leftovers in the opened tin
Product instructions for the identified Princes, M&S, ASDA and Morrisons tins call for unused tuna to be transferred to a non-metallic container, refrigerated and used within two days.
Follow your tin’s label, and move leftovers to a covered non-metallic container promptly.
-
Serving without checking allergen information
Tuna contains fish, an allergen that matters when guests are choosing from a buffet.
Check the exact tin’s ingredients and allergen panel, and keep that information available for guests. Do not serve it to someone with a fish allergy.

Common questions
How many single tins do I need for a Boxing Day buffet?
Use the drained weight if your recipe calls for drained tuna. For instance, the Princes 145g brine tin lists 102g drained weight; divide the amount your dish needs by the drained quantity on the tin you choose.
Should I use brine, spring water or oil for tuna mayo?
Brine or spring water lets you build the flavour with your own mayonnaise and seasoning. Choose an oil-packed variety if you want the oil’s flavour in the dish, and check that variety’s nutrition panel rather than treating the three liquids as interchangeable.
What should I do with tuna left after opening the tin?
Follow the instructions on your tin. The identified Princes, M&S, ASDA and Morrisons product pages direct shoppers to transfer unused tuna to a non-metallic container, refrigerate it and use it within two days.
What allergen information should I check before serving guests?
Check the ingredients and allergen panel on the exact tin: tuna contains fish. Keep that information available with the buffet so guests can identify the dish, and do not serve it to someone with a fish allergy.
Does an MSC label on one tuna tin cover the whole brand?
No. Look for the MSC label on the specific tin you intend to buy; a certification claim for another product or range does not establish the status of this one.
