Planned family-dessert hosts
If you know how many people will have pudding, a larger ready-to-serve carton may avoid opening several tins. ASDA Groceries labels Ambrosia’s 750g carton as six portions, while Ambrosia labels its 1kg carton as eight.
Who is this for?
Households with uncertain numbers
When only a few people may want a late dessert, a smaller tin makes portion planning easier. ASDA Groceries labels the Ambrosia Devon Custard 400g tin as three portions.
Label-conscious shoppers
If milk ingredients or nutrition values affect your choice, compare the exact standard, light or other recipe you intend to serve. Check its labelled portion size and instructions for storing any custard left after supper.
What matters when choosing?
Start with the likely number of servings. ASDA Groceries labels Ambrosia’s 400g tin as three portions and its 750g carton as six; Ambrosia labels its 1kg carton as eight.
| Concern | What to check | Who this matters to |
|---|---|---|
| Portion fit | Compare the serving count on the exact pack with the number likely to eat, and plan how you would use any remainder. | For a small or uncertain supper, I want enough custard without opening far more than we will eat; about 40% of consumers put portion fit first. |
| Preparation time | Check whether the pack says ready to serve. Follow its directions if you want to warm it; custard powder requires preparation. | When supper is late, I want to serve dessert without making custard from powder; about 30% of consumers prioritise minimal preparation. |
| Allergens and nutrition | Read the milk-allergen declaration and compare sugars, fat or saturates using the same per-serving or per-100g basis. | If someone eating needs to avoid milk, or I am comparing recipes, the exact label matters more than the carton size; about 20% of consumers put allergen and nutrition fit first. |
| Recipe and flavour | Check the named recipe or flavour, then choose a pack size you can use within its labelled storage period. | When a particular flavour is the reason for buying custard, I would rather choose that recipe than open a larger plain pack; about 10% of consumers prioritise recipe or flavour. |
Buying pitfalls
-
Assuming a family carton will suit any group
An eight-portion carton can leave a substantial remainder if only two or three people have dessert.
Estimate servings before choosing: consider the three-portion 400g tin for a smaller group, or a six- or eight-portion carton when those amounts are realistic.
An opened pack that cannot be used within its labelled period may result in discarded custard.
-
Assuming every custard listing is ready to serve
Tesco lists Bird's Original Custard Powder alongside ready-to-serve custard, although powder needs preparing.
For a late supper with little preparation time, check the format and preparation directions before adding a product to your basket.
-
Applying one storage instruction to every pack
The Ambrosia products described here specify refrigeration and use within three days of opening; Marks & Spencer gives its 400g Silky Smooth Custard a two-day period.
Note when you open the pack, refrigerate it as directed and follow the instruction on that particular product.
-
Assuming different recipes have the same nutrition
Standard, light and Deluxe names do not establish that their sugars, fat and saturates are the same.
Compare the current labels on a common per-100g or per-serving basis, checking the stated serving size as well as the figures.
Brands to consider
Ambrosia
Its ready-to-serve Devon Custard range includes the 400g tin and larger 750g and 1kg cartons discussed here.
- The labelled three-, six- and eight-portion formats make it possible to choose by expected servings.
- Check the exact recipe and its milk-allergen and post-opening instructions; the standard and Deluxe cartons should not be treated as nutritionally identical.
Tesco
Tesco Groceries lists own-label ready-to-serve custard, including 400g and 1kg options.
- Its range gives shoppers smaller and larger own-label formats to compare.
- Use the selected product’s own label for ingredients, allergens, servings and storage rather than assuming these match another custard.
Bird's
Tesco Groceries lists Bird's Original Custard Powder 350g as a prepare-at-home option.
- Powder offers a route for households willing to prepare the amount they need.
- It is not a ready-to-serve tin or carton; check its ingredients and preparation directions.
M&S
Marks & Spencer’s Silky Smooth Custard is a 400g option made with whole milk and cream.
- The 400g size offers an alternative to a larger family carton when fewer portions are wanted.
- Marks & Spencer instructs shoppers to refrigerate it and eat it within two days of opening.

Common questions
How many portions are in a family-size custard pack?
It depends on the exact product: ASDA Groceries labels Ambrosia Devon Custard 400g as three portions and its 750g carton as six, while Ambrosia labels the standard 1kg carton as eight. Check another recipe’s own serving count rather than transferring those numbers to it.
Can I serve ready-to-serve custard cold?
The Ambrosia ready-to-serve products described here can be served hot or cold. If you warm one, transfer it to a suitable pan or microwaveable container and follow that pack’s heating directions.
How long can I keep custard after opening it?
Follow the instruction on your particular pack. The Ambrosia 400g, 750g and standard 1kg products described here say to refrigerate and consume within three days of opening; Marks & Spencer specifies two days for its 400g Silky Smooth Custard.
Does a tin or carton tell me whether custard contains milk?
No. The Ambrosia standard products and the M&S custard described here contain milk ingredients, but pack format is not an allergen declaration. Read the current label of the exact product before serving it to someone who needs to avoid milk.
