Households serving several children
If custard will be part of repeated lunches at home, the useful pack size depends on how many portions you will serve and whether you can finish an opened pack in time.
Who is choosing?
Families packing individual lunches
For an outing, childcare or a lunchbox, a self-contained portion avoids dividing a tin before leaving home. Consider how the dessert will be carried and kept cool.
Households checking food labels
If sugar and fat figures or milk ingredients affect your choice, compare the nutrition and allergen information on the exact product you intend to serve.
What matters when choosing?
Start with the number of portions you need, then consider whether lunch is at home or being carried elsewhere.
| Concern | What to check | Who this matters to |
|---|---|---|
| Pack size and portions | Compare net weight with the portions you plan to serve and the opened-pack storage instructions. Ambrosia states that its 400g Devon Custard tin serves three. | When I am serving custard across several lunches, I want a pack I can finish without leaving too much behind. About 31% of consumers would put pack size and portions first. |
| Preparation and carrying | Check whether the product is ready to serve or needs preparation. For an outing, plan how a dairy dessert will be kept cool; GOV.UK advises cool bags or boxes with frozen ice packs. | If lunch is away from home, I need a portion that is straightforward to pack and serve. Ready-to-serve convenience would come first for about 31% of consumers. |
| Sugar and fat labels | Compare the exact packs on the same per-100g or per-serving basis. Ambrosia describes its Light 400g custard as having 30% less sugar and 30% less fat than its standard Devon Custard. | For a dessert served regularly during the holidays, I want to compare the sugar and fat figures before choosing a tin. Roughly 23% of consumers would make that label comparison their primary concern. |
| Ingredients and allergens | Read the current ingredients and allergen declaration on each pack, including any powder and the ingredients used to prepare it. GOV.UK says the 14 regulated allergens in prepacked food must be clearly labelled in the ingredients list. | When someone eating lunch needs an ingredient checked, I cannot choose by pack size alone. For about 15% of consumers, ingredients and allergens would be the first consideration. |
What should you watch for?

Planning around a listed multipack
A multipack listing does not establish that the pack will be available when you shop. Tesco listed an Ambrosia 4 × 400g bundle as out of stock when checked.
Confirm the pack count and current availability before planning how many lunches it will cover.
-
Assuming a 400g tin is one portion
Ambrosia states that its 400g Devon Custard tin serves three. It instructs shoppers to remove the remaining custard from the can, refrigerate it and use it within three days of opening.
Match the tin to the portions needed at that meal, and follow the exact pack's directions for any leftovers.
Custard left over after the stated opened-pack period may go to waste.
-
Treating a nutrition claim as an allergen check
Ambrosia's Light comparison is with its own standard Devon Custard; the examined Light product still lists milk ingredients.
Read the nutrition panel and allergen declaration separately on the product you are buying.
-
Packing an opened dairy dessert without cooling
An opened, portioned dessert needs different planning from an unopened ambient pack. GOV.UK advises keeping dairy foods cool outside, using a cool bag or box and frozen ice packs.
For a day out, arrange suitable cooling for custard portioned in advance, or consider an unopened shelf-stable portion that can be opened when it is served.
Brands to consider
Ambrosia
Ready-to-serve 400g custard tins include standard and Light variants, offering different labels to compare within the same pack size.
- Ambrosia states that its examined 400g standard and Light tins each serve three and can be eaten hot or cold.
- The brand directs shoppers to refrigerate remaining custard and use it within three days of opening. Both examined products contain milk ingredients.
Tesco
Tesco lists own-brand ready-to-serve custard in 400g and 1kg formats, making portion planning relevant when choosing between them.
- The 1kg format offers a larger quantity without preparing custard from powder.
- Check the exact pack's opened-storage instructions before choosing a size for repeated lunches.
Bird's
Bird's custard powder is an alternative for lunches prepared at home, rather than a ready-to-serve tin.
- Bird's preparation directions use milk and sugar, with quantities that can be varied when making the custard.
- Preparation takes additional ingredients and time. Bird's says made-up custard should be refrigerated and treated as fresh food; check the powder's own allergen declaration too.
M&S
M&S Silky Smooth Custard is a ready-to-serve option for shoppers comparing recipes as well as pack sizes.
- M&S describes this custard as made with whole milk.
- M&S directs shoppers to refrigerate it and eat it within two days of opening, so check whether an opened pack fits your meal plan.

Ambrosia Low Fat Custard 400g

Questions about custard for holiday lunches
Should I choose a larger pack for lunches throughout the holidays?
Choose a larger ready-to-serve pack if you can use its portions within the opened-pack period and keep leftovers refrigerated. Opened-storage instructions differ: Ambrosia states three days for its examined 400g tins, while M&S states two days for its Silky Smooth Custard.
Can opened tinned custard go in a lunchbox for a day out?
Plan to keep an opened, portioned dairy dessert cool. GOV.UK's heatwave food-safety guidance advises using a cool bag or box with frozen ice packs for dairy foods taken outside.
How do I check whether a custard contains milk?
Read the current ingredients and allergen declaration on the exact pack before serving it. GOV.UK says that regulated allergens in prepacked food must be clearly labelled in the ingredients list; the examined Ambrosia ready-to-serve tins contain milk ingredients.
Is custard powder a substitute for ready-to-serve tins?
Custard powder works for a lunch you have time to prepare, but it is not ready to eat from the pack. Bird's directions use milk and sugar, and the brand says prepared custard should be refrigerated and treated as fresh food. Check both the powder and anything added to it if ingredients matter.
