Households planning several lunches
A ready-to-serve tin can be kept in the cupboard until needed. Check its weight and serving guidance against the lunches you have in mind.
Who is choosing?
Households serving small portions
If one meal will use only part of a 400g tin, the instructions for refrigerating and using the remainder become part of the choice.
Shoppers comparing recipes
If listed sugars or fat matter to your choice, compare nutrition on the same per 100g basis. Check the current ingredients separately: a light or low-fat name does not mean a custard is free from milk.
What matters when choosing?
For school-holiday lunches, decide how many servings you need, whether you can use an opened tin in time, and which recipe details matter to your household.
| Concern | What to check | Who this matters to |
|---|---|---|
| Servings for repeated lunches | Check the tin weight and stated portions against the servings you plan to use. | When planning lunches across the holidays, I want to know whether one tin covers the servings I have in mind. About 50% of consumers would put that planning need first. |
| Leftovers after opening | Read the individual tin's refrigeration and use-by instructions after opening. | If one lunch needs only a little custard, I need a plan for the rest before opening a 400g tin. Using leftovers in time would come first for about 30% of consumers. |
| Recipe and ingredients | Compare nutrition per 100g and read the current ingredients and allergen declaration. | For some lunches, I would choose between recipes by their listed sugars and fat, while still checking for milk. Roughly 20% of consumers would make the recipe their primary concern. |
Checks that are easy to miss

Treating custard powder as a ready-to-serve tin
Bird's Original Custard Powder needs preparation; it is a different choice from custard that can be served straight from a tin.
If you are considering powder, check the preparation instructions and what you would need to add before deciding which format fits lunch at home.

Opening a 400g tin for one small serving
Opened-pack instructions differ. Ambrosia says to refrigerate remaining Devon Custard and consume it within three days; M&S says to refrigerate its Silky Smooth Custard and eat it within two days.
Plan when you will use the remainder and follow the instructions on the tin you buy. Ambrosia also directs you to remove its remaining custard from the can.
Custard left unused beyond the stated period may have to be discarded.

Assuming a light recipe is free from milk
Ambrosia's standard and Light Devon Custard product information identifies milk ingredients. GOV.UK states that regulated allergens in UK prepacked food must be clearly identified in the ingredients list.
For an allergy or intolerance decision, read the physical pack's current ingredients and allergen declaration rather than relying on a recipe name or an earlier purchase.
Brands and formats to consider
Tesco
Tesco lists a 400g own-label Ready To Serve Custard tin alongside branded tinned custards.

- Check its current label and serving information rather than assuming it matches another tin's recipe or portions.

- Ambrosia states that its standard 400g Devon Custard can provides three 130g portions and can be served hot or cold.

M&S
M&S lists Silky Smooth Custard in a 400g can made with whole milk and cream.
- The stated ingredients give shoppers a way to identify the recipe they want.
- M&S instructs shoppers to refrigerate the custard after opening and eat it within two days.
Bird's
Bird's Original Custard Powder is a cupboard ingredient to prepare, rather than a ready-to-serve tin.

- Check its preparation instructions and added ingredients before comparing the finished servings with a tin.

How many portions are in a 400g Ambrosia Devon Custard tin?
