Hosts comparing salt labels
If salt is your priority, compare the same per-100g measure across tins before working out how much custard each guest might have. The cited ASDA, Sainsbury’s and M&S listings provide figures for specific 400g products.
Who this is for
Hosts planning for leftovers
If some custard may remain after the party, opened-pack instructions matter. The cited retailer listings give different refrigeration and use-within periods for the Sainsbury’s, M&S and Ambrosia tins.
Buyers balancing two nutrition priorities
If you want a low-fat variant as well as a lower salt figure, check each declaration separately. Sainsbury’s lists Ambrosia Low Fat Custard as low fat, but that wording does not establish its salt content relative to another tin.
What to check when buying
| Concern | What to check | Who this matters to |
|---|---|---|
| Salt declaration | Compare salt per 100g on the current packs, then consider the amount you intend to serve. Check salt separately from low-fat wording. | If I am choosing custard with salt foremost in mind, I need a like-for-like label comparison rather than relying on the front of the tin. About 50% of consumers put that salt check first. |
| Party portions | Check the tin’s net weight and stated servings against the portions planned for your guests. | When custard is one part of a party dessert, I want enough for guests without assuming every 400g tin represents the same number of servings. For about 25% of consumers, portion planning is the primary concern. |
| Serving and leftovers | Read the product’s heating, milk-allergen and opened-pack storage instructions before serving. | If guests will have custard at different times, I need to know how to serve it and handle what remains. Leftover and serving arrangements come first for about 25% of consumers. |
Buying pitfalls
-
Assuming low fat means reduced salt
Sainsbury’s identifies Ambrosia Low Fat Custard as low fat; that description does not establish a reduced-salt claim.
Compare salt per 100g on the current label. Check fat or sugar separately if either matters to your choice.
-
Comparing salt per serving without comparing portions
ASDA lists three 130g portions for Ambrosia Devon Custard 400g, while Sainsbury’s states two servings for its Stamford Street Co. 400g tin. Their per-serving figures therefore refer to different amounts of custard.
Start with salt per 100g, then use the amount you actually plan to serve to compare portions.
-
Overlooking the instructions after opening
The cited retailer instructions give one day after opening for Sainsbury’s Stamford Street Co. Custard, two days for M&S Silky Smooth Custard and three days for Ambrosia Devon Custard, with refrigeration required.
Transfer leftover Ambrosia or Sainsbury’s custard out of the can as instructed, and follow the storage directions on the specific pack.
A tin opened too early for the party plan may leave custard that cannot be used within its stated storage period.
-
Assuming ready-to-serve custard is dairy-free
The cited Ambrosia, Sainsbury’s and M&S products contain milk, which matters when catering for guests with a milk allergy.
Check each current allergen statement and, if needed, choose a separately verified dairy-free dessert for those guests.
Brands to consider
Ambrosia
Ambrosia has 400g Devon Custard and Low Fat Custard tins in the cited UK retailer listings.
- ASDA lists 0.11g salt per 100g for Devon Custard 400g and says it can be served hot or cold.
- Devon Custard contains milk. The Low Fat variant needs its own salt-label check; its name does not establish reduced salt.
Sainsbury’s / Stamford Street Co.
Sainsbury’s lists a ready-to-eat Stamford Street Co. custard in a 400g tin.
- The Sainsbury’s listing states 0.10g salt per 100g and two servings per tin.
- After opening, its instructions say to transfer the custard to a non-metallic container, refrigerate it and use it within one day.
M&S
M&S lists Silky Smooth Custard as a 400g custard made with whole milk.
- The M&S listing states 0.10g salt per 100g and says to refrigerate after opening and eat within two days.
- It contains milk and cream; check the current pack if ingredients or allergens affect your choice.
Tesco
Tesco Groceries lists Tesco Ready To Serve Custard 400g among its tinned custards.
- Its 400g format gives party shoppers another tin to assess for their planned portions.
- Check its current salt declaration before comparing it with the tins whose per-100g figures appear above.
Bird’s
Bird’s Original Custard Powder is an option if making custard is acceptable instead of opening a ready-to-serve tin.
- Powder is not a like-for-like tinned option. The prepared custard depends on the recipe and ingredients used, so compare the finished serving rather than the powder alone.

Ambrosia Strawberry Flavour Devon Custard 400g
If strawberry flavour suits the desserts you plan to serve, this 400g tin is one option. Check its own salt-per-100g declaration and serving information; it is a distinct variant from Ambrosia Devon Custard in the retailer comparison above.
Image unavailable
Ambrosia Low Fat Custard 400g
If a low-fat variant is a separate priority for the party, consider this 400g tin alongside your salt comparison. Check its current salt declaration and planned serving size independently: low-fat wording does not establish reduced salt.
