Salt-conscious dessert hosts
If salt is the main consideration, compare the declared amount per 100g on each exact pack. A Light label describes a different product claim and does not establish that the custard has less salt.
Who is choosing custard?
Low-effort party dessert planners
Ready-to-serve custard can accompany crumble, pudding or fruit without making custard from scratch. Check whether the chosen product can be served at the temperature you want and how leftovers must be stored.
Party quantity planners
When serving several guests, match the pack size to the desserts and likely portions. Check salt and milk-allergen information on the chosen pack rather than assuming that different sizes share the same declaration.
What matters when buying?
Start with the salt declaration for the exact product, then choose a pack and serving method that fit the dessert table.
| Concern | What to check | Who this matters to |
|---|---|---|
| Declared salt | Compare salt per 100g on the exact pack, then check the amount for the portion you plan to serve. Do not read a Light claim as a salt claim. | I want to choose custard by its salt declaration rather than its front-of-pack wording. About 42% of consumers put that comparison first. |
| Serving and storage | Check hot-or-cold serving directions, heating instructions and the refrigerated storage period after opening. | If desserts need to be served quickly, I want custard I can prepare as directed and leftovers I can use in time. Serving convenience comes first for about 33% of consumers. |
| Pack quantity | Match the pack size to expected portions and any planned use for leftovers; check the nutrition and allergen label on that size. | With several desserts to serve, I need enough custard without opening more than we can use. About 25% of consumers prioritise the quantity they need. |
What should you avoid overlooking?
-
Assuming Light means less salt
Ambrosia says its Light Devon Custard can has 30% less sugar and fat than its standard Devon Custard. Ambrosia declares 0.12g salt per 100g for the Light can, compared with 0.11g for the standard can.
If salt drives your choice, compare the salt line on the current packs separately from sugar and fat claims.
-
Looking only at a stated portion
Portion sizes can differ, and guests may serve themselves more than once. The NHS says its adult daily salt guidance includes salt already in food as well as salt added during cooking or at the table.
Compare custards per 100g first, then consider the portions and the rest of the party menu.
-
Opening more custard than you can use
Ambient storage before opening does not mean an opened can can stay in the cupboard. Ambrosia instructs shoppers to refrigerate remaining custard and use it within 3 days; M&S gives 2 days for its Silky Smooth Custard.
Choose a pack size around expected servings and follow the exact pack's instructions for transferring and refrigerating leftovers.
Custard left beyond its labelled storage period may go to waste.
-
Forgetting the milk-allergen check
The Ambrosia standard and Light cans and M&S Silky Smooth Custard contain milk ingredients. Serving custard as a topping does not remove that concern for a guest with a milk allergy.
Read the current allergen declaration before serving and arrange a separately checked alternative if a guest needs one.
Brands to consider
Ambrosia
Ambrosia offers standard and Light ready-to-serve Devon Custard in 400g cans that can be served hot or cold.
- Ambrosia declares 0.11g salt per 100g for the standard can and 0.12g for the Light can.
- Ambrosia's claim of 30% less sugar and fat for Light is relative to its standard Devon Custard; it is not a lower-salt claim. Both cans contain milk and require refrigeration after opening.
M&S
M&S Silky Smooth Custard comes in a 400g ambient can.
- M&S declares 0.10g salt per 100g for this product, below the declarations for the standard and Light Ambrosia cans described here.
- It contains milk. M&S instructs shoppers to refrigerate it after opening and eat it within 2 days.
Sainsbury's
Sainsbury's lists own-label ready-to-eat ambient custard in 500g and 1kg formats.
- The larger listed formats give hosts pack sizes to consider when planning portions.
- Sainsbury's declares 0.15g salt per 100g for its Ready To Eat Custard 500g, which contains cows' milk. Do not transfer that figure to a different pack.
Tesco
Tesco lists a 400g Ready To Serve Custard in its tinned-custard range.
- The listed 400g size offers another can to consider for party portions.
- Read its current pack's salt declaration before comparing it with custards whose per-100g figures are given here.

Ambrosia Devon Custard 400g
A 400g ready-to-serve can for serving custard hot or cold with party desserts. Ambrosia declares 0.11g salt per 100g for its standard Devon Custard can. It contains milk; after opening, transfer remaining custard from the can, refrigerate it and use it within 3 days.

Ambrosia Strawberry Flavour Devon Custard 400g
The strawberry-flavour variant offers a different flavour for the dessert table. It is a 400g pack; check this variant's current salt and milk-allergen declarations rather than using the figures for standard Devon Custard.

Morrisons Ready To Serve Custard 500g
Consider this 500g ready-to-serve pack if you need more custard than a 400g can. Check the pack format if a tin matters, and read its current salt and milk-allergen declarations before serving.
No image available
Ambrosia Low Fat Custard 400g
This 400g Low Fat variant is another pack size for a dessert table. Low Fat does not itself describe the salt content: check this exact pack's salt declaration rather than applying the standard can's figure. Check the milk-allergen label and storage directions too.
No image available
Ambrosia Light Devon Custard 1kg
The 1kg Light pack is an option when planning custard for a larger group. Confirm its format, current salt declaration and opened-pack storage directions on this exact product; the declared salt figure for Ambrosia's 400g Light can should not be assumed to apply to the 1kg pack. Check the milk-allergen label before serving.
Questions about serving and salt
Is Light custard automatically lower in salt?
No. Ambrosia says its 400g Light Devon Custard can has 30% less sugar and fat than its standard Devon Custard, but declares 0.12g salt per 100g for Light and 0.11g for the standard can. Read the salt line on the exact pack you intend to serve.
How should I compare custards for a salt-conscious dessert table?
Compare declared salt per 100g on the exact packs, then consider the portions guests are likely to take. The NHS says its adult daily salt guidance covers salt already in food and salt added during cooking or at the table, so custard is only one part of the menu to consider.
Can I heat Ambrosia custard in its tin?
No: follow Ambrosia's instructions to empty the custard into a saucepan for hob heating or a microwaveable container for microwave heating. Heat it gently, stir and do not boil it.
How long can I keep opened custard?
Follow the exact product label. Ambrosia instructs shoppers to remove remaining custard from its cans, refrigerate it and use it within 3 days; M&S says to refrigerate opened Silky Smooth Custard and eat it within 2 days.
Can guests with a milk allergy have these custards?
The Ambrosia standard and Light cans and M&S Silky Smooth Custard contain milk ingredients, so they are not milk-free choices. Check every exact pack's current allergen declaration before serving, particularly when offering other variants.
