Salt-first comfort-dinner shoppers
You want ready-to-serve custard and will compare salt per 100g before relying on low-fat wording or pack design.
Who is choosing custard?
Lighter-dessert buyers
You want custard to serve hot or cold, but lower fat matters alongside salt. A low-fat variant is not necessarily the option with the lowest declared salt.
Convenience-led pudding planners
You need custard for a dessert such as crumble, cake or fruit, and want a pack size and opened-pack storage period that suit the meal.
What matters when buying?
For a ready-to-serve custard at a comfort dinner, compare salt per 100g first if that is your priority; then check the recipe and how much of the pack you expect to use.
| Concern | What to check | Who this matters to |
|---|---|---|
| Declared salt | Compare salt per 100g on ready-to-serve packs; use the serving figure for the portion you plan to eat. | If salt is my deciding factor, I need a like-for-like figure rather than a low-fat label or a colour alone. About 46% of consumers put declared salt first. |
| Fat and recipe | Read fat and saturates per 100g alongside salt, and check ingredients if milk or cream affects your choice. | When I want a less rich custard with pudding, the recipe may matter more to me than the lowest salt figure. About 27% of consumers make that their primary concern. |
| Serving and leftovers | Check pack weight and the instructions for heating, refrigeration and use after opening. | If I am serving only part of a pack, I need to know whether the remainder will fit another meal. About 27% of consumers put serving convenience and leftovers first. |
Buying pitfalls
-
Assuming low fat means lower salt
Tesco Groceries lists 0.12g salt per 100g for Ambrosia Low Fat Custard, while Marks & Spencer lists 0.10g for M&S Silky Smooth Custard. The two choices answer different priorities.
Compare salt, fat and saturates per 100g, then decide which label value matters for this dessert.
-
Comparing salt in unequal servings
The checked Ambrosia serving is 130g, while the Tesco and Sainsbury's serving figures use 125g. Salt amounts for those servings are not a direct like-for-like comparison.
Compare products per 100g first, then read the figure for the portion you intend to serve.
-
Treating powder as ready-to-serve custard
Bird's Original Custard Powder requires preparation with milk and sugar according to Bird's instructions. It cannot be compared with a ready-to-serve tin using the dry powder's nutrition values alone.
Choose powder when you want to make the custard; choose a ready-to-serve product when preparation time is the deciding issue.
-
Overlooking milk and opened-pack instructions
The checked ready-to-serve products contain milk. Marks & Spencer says to refrigerate M&S Silky Smooth Custard and eat it within 2 days of opening; several other checked products specify 3 days.
Check the physical pack for allergens and follow its storage and transfer instructions for any leftovers.

Questions about custard
Does a green salt traffic light mean custard is reduced salt?
No. Food Standards Agency guidance presents traffic lights as a way to compare labelled salt content; a green indication alone does not establish a reduced-salt claim. Check the pack wording and compare salt per 100g.
Can someone with a milk allergy have these ready-to-serve custards?
Do not assume so: the checked Ambrosia, Tesco, ASDA, Sainsbury's and M&S products contain milk. Check the allergen information on the physical pack before serving.
How long can opened custard be kept?
Follow the instructions on the specific pack. Marks & Spencer says to refrigerate Silky Smooth Custard and eat it within 2 days of opening; the checked Ambrosia, Tesco, ASDA and Sainsbury's products specify 3 days. Transfer leftovers from a can when its label instructs you to do so.
Can I heat custard in its can?
Transfer it out of the can before heating. The checked Tesco, ASDA and Sainsbury's instructions describe heating the contents in a suitable pan or dish; follow the method and precautions on your pack.
