Hosts serving pudding once
Plan the amount you expect to pour before deciding how many packs to open. Ambrosia labels its 400g can as three 130g portions and its 1kg carton as eight 125g portions, giving two different ways to plan a shared dessert.
Who is choosing custard?
Households buying several packs
Check whether a listing is for one can, several cans or a carton. Buying multiple individual tins lets you leave some unopened if fewer people come to dinner; a large carton calls for a plan to use what remains after opening.
Families checking dietary requirements
Read the ingredients and allergen information on the pack that will be served. The Ambrosia and Tesco products considered here contain milk, so their labels matter when planning dessert for someone with a milk allergy.
What matters when choosing a pack?
Several 400g tins
Choose when: You want to open only the cans needed for dinner or are unsure how many people will want custard.
Bear in mind: A listing for one tin is not a multipack, and any custard left in an opened can needs to be stored as its label directs.
One 1kg carton
Choose when: A larger group is likely to use most of a ready-to-serve pack; Ambrosia labels its 1kg Devon Custard carton as eight portions.
Bear in mind: A carton does not meet a tinned-only preference, and a partly used carton needs refrigerated storage.
Foodservice case
Choose when: You repeatedly need large quantities; Premier Foodservice describes its Bird's ready-to-serve custard case as 12 × 1kg cartons.
Bear in mind: It is neither a household multipack of tins nor a practical quantity for most one-off family dinners.
| Concern | What to check | Who this matters to |
|---|---|---|
| Portions and leftovers | Compare the stated serving size with the amount you intend to pour. Check the opened-pack storage instructions. | If fewer relatives want pudding than expected, I would rather leave a tin unopened than have custard left over. About 42% of consumers put manageable portions and leftovers first. |
| Pack quantity and format | Confirm whether the listing is for an individual can, a carton or a case, and check its net weight. | When buying ahead for family dinners, I need to know how many separate packs I am ordering, not just their combined quantity. Roughly 33% of consumers make pack quantity and format their main concern. |
| Ingredients and allergens | Read the exact pack's ingredients and allergen declaration before serving. | With different dietary requirements at the table, I need to check whether the custard contains milk. For about 25% of consumers, ingredient and allergen fit comes first. |
Mistakes to avoid
-
Assuming a large pack is a bulk tin
Ambrosia's 1kg ready-to-serve Devon Custard is a carton, whereas its 400g product is a can. The difference matters if you specifically want tins that can be opened one at a time.
Check the packaging format and net weight, as well as the number of packs, before ordering.
-
Keeping custard in an opened can
Ambrosia instructs customers to remove the remaining custard from its 400g can and refrigerate it for use within three days. Tesco also instructs customers to transfer unused custard from its 400g can to a covered, non-metallic container; M&S gives a two-day refrigerated-use period for its 400g custard.
Follow the instructions on the can you open, and note when you opened it.
If the planned meal will use only a little of a large pack, consider whether the remainder can be used within its stated period.
-
Assuming every custard suits everyone
The Ambrosia, Tesco, M&S and Bird's products described here contain milk. An older product listing is no substitute for the label on the pack being served.
Check that pack's ingredients and allergen information for anyone with an allergy or other dietary requirement.
Brands to consider for these pack formats
Ambrosia
Its ready-to-serve Devon Custard comes in a 400g can and a 1kg carton.
- The can is labelled as three 130g portions; the 1kg carton is labelled as eight 125g portions.
- The larger format is not a tin. Both formats contain milk and require refrigeration after opening.
Tesco
Tesco offers own-label ready-to-serve custard in a 400g can and a 500g format.
- The two sizes offer different quantities for planning a family dessert.
- Both contain milk and carry instructions to refrigerate and use the custard within three days of opening.
M&S
Its 400g canned custard lists whole milk, skimmed milk, cream and whey powder among its ingredients.
- The ingredient list helps shoppers compare recipes before choosing a custard for dessert.
- The can contains milk; M&S instructs customers to refrigerate it after opening and eat it within two days.
Bird's
Premier Foodservice lists Bird's ready-to-serve custard in a case of 12 × 1kg cartons.
- The case format is relevant to repeated large-volume serving.
- It is not a multipack of tins. The custard contains milk, and opened cartons must be refrigerated and used within three days.

These two ready-to-serve Ambrosia packs offer a choice between opening a 400g tin and serving from a larger 1kg carton. Check the variant carefully: the carton listed here is Ambrosia Light Devon Custard.

Ambrosia Devon Custard 400g can
Choose individual cans if you want to open only the quantity needed for a family pudding; this listing is for one can, not a multi-can bundle. Ambrosia labels the 400g can as three 130g portions. It contains milk, and any remaining custard must be removed from the can, refrigerated and used within three days of opening.
No image available
Ambrosia Light Devon Custard 1kg carton
Consider this carton when the dinner calls for around eight servings and you expect to use most of it promptly. Its product description states approximately eight servings; it is a carton rather than a tin. It contains milk and must be refrigerated and used within three days after opening.
Questions about serving and storage
How many people does a 400g tin of custard serve?
Use the portion information on the particular tin rather than assuming every 400g can serves the same number. Ambrosia labels its can as three 130g portions, while Tesco presents nutrition for a 200g half-can serving. Decide how much you plan to pour over each dessert before calculating the number of cans.
When does a 1kg carton make sense for dinner?
A 1kg carton is worth considering when its stated servings are close to the amount your group will eat. Ambrosia labels its 1kg Devon Custard carton as eight 125g portions, but it is not a tin; refrigerate any remainder and follow the carton's opened-pack time limit.
Can I heat custard in the can?
Transfer the custard out of the can before heating it. Follow the particular pack's microwave instructions using a suitable container, or use a saucepan for hob heating as directed on the label.
How should leftover canned custard be stored?
Remove the remainder from the can and follow its label's refrigeration instructions. Ambrosia and Tesco specify use within three days for their cited 400g cans, while M&S specifies two days for its cited 400g custard.
Where should I check for milk allergens?
Check the ingredients and allergen information on the physical pack before serving. For prepacked food, the Food Standards Agency says allergens present must be emphasised in the packaging's ingredients list. The custards discussed here contain milk, so they are unsuitable for someone with a milk allergy.
