Salt-conscious party hosts
If salt is the deciding factor, compare the figure per 100g across ready-to-serve tins. A front-of-pack description such as low fat answers a different question.
Who is choosing custard?
Hosts serving a crowd
Work out whether custard will be a small topping for cake or fruit or a larger dessert accompaniment. Pack size and stated servings can help you plan, but guests may take different amounts.
Allergy-aware dessert planners
Check the ingredients of every tin before serving guests with dietary requirements. The ready-to-serve custards considered here contain milk, and opened-pack storage instructions differ.
What matters when choosing?
Start with a like-for-like salt comparison, then plan portions and service around the guests and dessert you have in mind.
| Concern | What to check | Who this matters to |
|---|---|---|
| Published salt | Compare salt per 100g on the current ready-to-serve tin; check any reduced-salt claim against its stated reference. | When salt determines my choice, I need a figure I can compare across tins rather than relying on recipe names. About 33% of consumers put the published salt value first. |
| Party quantity | Check pack mass and stated servings against the amount you intend to serve with each dessert. | If custard is going alongside cake for a crowd, running short matters more to me than choosing a particular recipe. For about 27% of consumers, planning enough portions is the primary need. |
| Ease of serving | Decide whether to serve it cold; if warming it, follow that tin's container and heating directions. | I want to put dessert out without making custard from powder during the party. Quick, manageable service comes first for about 20% of consumers. |
| Guest suitability | Read the milk-allergen declaration and the instructions for storing custard after opening. | With guests who may have a milk allergy, I need to establish what they can be served before opening a tin. About 20% of consumers prioritise guest suitability and leftover handling. |
What should you avoid overlooking?
-
Assuming low fat means less salt
Joybuy lists 0.12g salt per 100g for Ambrosia Low Fat Custard 400g, while Sainsbury's, Tesco and ASDA each list a standard 400g custard at 0.10g per 100g.
Read salt per 100g on the exact tin you are buying. Compare fat or other nutrition values separately if they also matter to you.
-
Counting tins without planning portions
The compared tins contain 400g, but their stated serving guidance differs. A topping for cake may call for a different amount from a larger serving alongside another dessert.
Decide how you will serve the custard, then use the pack's serving guidance to plan how many tins to open.
-
Taking vegetarian to mean dairy-free
The checked ready-to-serve tins contain milk. A vegetarian label does not resolve whether a guest with a milk allergy can have the dessert.
Read the ingredients and allergen declaration on the physical pack before serving, and arrange a separate suitable dessert where needed.
-
Heating custard in the can or overlooking leftovers
The checked heating directions require custard to be transferred out of the can. Instructions for reheating and for keeping an opened pack vary between products.
If serving it warm, use the container and method specified on the tin. Refrigerate opened custard as directed and follow that pack's use-by-opening instructions.
Brands and product lines to consider
These product lines offer different recipes and formats. Compare the specific tin rather than treating a brand name as a salt indication.
Ambrosia
Ambrosia offers 400g Devon Custard tins, including standard and Low Fat variants.
- The standard Devon Custard can be served hot or cold; ASDA and Joybuy list 0.11g salt per 100g for this 400g product.
- Joybuy lists 0.12g salt per 100g for the 400g Low Fat variant, so the variant name is not a shortcut for choosing less salt. Both checked variants contain milk.
Tesco

- Both contain milk. ASDA's instructions say not to boil or reheat them.

Common questions
How do I compare salt between tinned custards?
Use the salt figure per 100g on each current pack, because stated serving sizes can differ. Among the checked 400g tins, Sainsbury's, Tesco and ASDA list products at 0.10g per 100g, while ASDA Creamy and standard Ambrosia Devon list 0.11g per 100g. Neither figure alone establishes a reduced-salt claim.
Can I heat custard in its tin?
Do not heat the checked custards in their cans. Transfer custard to a saucepan or a suitable microwave-safe container, then follow the particular pack's directions; ASDA's checked tins also say not to boil or reheat.
Can a guest with a milk allergy have these custards?
The checked ready-to-serve tins contain milk, so do not assume they are suitable for a guest with a milk allergy. Read the ingredients and allergen declaration on the exact pack, and provide a separate suitable dessert where needed.
How long does opened tinned custard keep?
Follow the instructions on the individual tin rather than using one rule for every brand. The checked M&S product says to refrigerate and eat it within two days of opening; transfer and storage directions on other tins may differ.
