A 400g tin makes sense for one-person desserts when you plan to use its remaining servings within that product’s after-opening period. Choose individual pots if you usually want one serving without managing an opened tin; custard powder is another option if you are willing to prepare the amount you need rather than serve it straight away. Check the serving guidance and storage instructions on the exact pack before choosing a larger format.
If you eat custard with one dessert at a time, compare the pack’s stated servings with how soon you expect to use the rest. Ambrosia labels its 400g Devon Custard can as three 130g portions; Sainsbury’s and Asda describe the cited 400g own-label products as two servings.
A ready-to-serve tin can be kept unopened according to its pack instructions. Once opened, it needs a place in your meal plans as well as your fridge: Ambrosia instructs shoppers to remove the remainder from its Devon Custard can, refrigerate it and use it within three days.
If you do not specifically need tinned custard, powder lets you prepare custard when required instead of opening a ready-to-serve pack. Bird’s describes its 350g Original Custard Powder as containing 40 portions; it requires preparation and carries a may-contain-milk statement.
For single-portion meals, decide how you want to divide the pack, then check what happens to any custard left after opening.
| Concern | What to check | Who this matters to |
|---|---|---|
| Portion fit | Compare pack weight and stated servings. Do not assume every 400g tin divides into the same number of portions. | If I serve custard with one dessert at a time, I want a pack that divides sensibly into my planned meals. About 33% of consumers put portion fit first. |
| After-opening storage | Read the exact pack’s refrigeration, transfer and use-within instructions before planning a second serving. | When my next dessert is a few days away, I need to know whether the remainder can be used within the labelled period. For about 27% of consumers, managing leftovers is the primary concern. |
| Ingredients and allergens | Check the current ingredient and allergen declarations; compare nutrition per 100g if choosing between recipes. | If milk is an allergy concern or I am comparing recipes, the current pack matters more than the format’s name. Ingredients are the main deciding factor for about 20% of consumers. |
| Serving or preparation | Decide whether custard must be ready to serve or whether you can prepare powder when needed. | Sometimes I want to serve dessert straight away; at other times, I would rather make only the amount required. About 20% of consumers chiefly weigh up that choice. |
Ambrosia states three 130g portions for its 400g Devon Custard can, while the cited Sainsbury’s and Asda 400g custards indicate two servings. The weight alone does not tell you how the maker suggests dividing it.
Use the serving statement as a planning guide, alongside the amount you normally put with a dessert.
After-opening instructions are product-specific. Ambrosia says to remove the remaining Devon Custard from its can, refrigerate it and consume it within three days; M&S says its Silky Smooth Custard should be refrigerated and eaten within two days.
Follow the instructions on your particular pack, including any direction to transfer the custard to another container.
The cited ready-to-serve custards declare milk or milk-derived ingredients, while Bird’s Original Custard Powder says it may contain milk. A change of format does not establish allergen suitability.
For an allergy, check the ingredient list and allergen declaration on the current physical pack.

This is an alternative if you would rather prepare custard when needed than open a ready-to-serve tin. Bird’s describes the 350g pack as containing 40 portions. It requires preparation, and its may-contain-milk statement matters if you are checking allergens; follow the pack’s instructions for storing custard once made.
Yes, if you expect to use the remaining custard within that tin’s after-opening period. Ambrosia labels its 400g Devon Custard can as three 130g portions, while Sainsbury’s and Asda indicate two servings for the cited 400g own-label products. Check the specific pack rather than treating 400g as one serving.
Follow the product’s transfer, refrigeration and use-within instructions. Ambrosia says to remove the remainder from its Devon Custard can, refrigerate it and consume it within three days; M&S gives two days for its Silky Smooth Custard. GOV.UK advises keeping food at 5°C or below when its label requires refrigeration after opening.
Transfer it before heating. The cited Ambrosia and Sainsbury’s instructions direct shoppers to use a saucepan or a suitable microwaveable container; follow your pack’s method rather than borrowing another product’s heating time.
Do not assume so. Bird’s Original Custard Powder says it may contain milk, and the cited ready-to-serve custards declare milk or milk-derived ingredients. Check the current physical pack’s allergen declaration for whichever product you choose.
