For a one- or two-person household, several 400g tins make sense if you use custard regularly but prefer to open one manageable pack at a time. Tesco and ASDA present their 400g tins on a roughly two-serving basis and instruct shoppers to refrigerate unused contents and use them within three days. A larger carton suits repeated servings over a few days; individual pots are worth considering when avoiding leftovers matters more than keeping cupboard stock.
If you serve custard with crumble, sponge or fruit, a 400g tin gives you a defined quantity to plan around without opening a larger carton. Tesco Groceries and ASDA Groceries each show a half-can serving basis for their 400g tins.
If desserts with custard are infrequent, decide what will happen to the rest of an opened pack before buying several. The Tesco, ASDA and Ambrosia tin instructions call for refrigerated leftovers to be used within three days.
If ingredients or nutrition determine your choice, compare the exact variant rather than treating ready-to-serve custards as interchangeable. The checked Tesco, ASDA and Ambrosia products contain milk; their labels provide the details needed to assess each pack.
Start with how much custard you will use after opening, then choose how many unopened packs to keep and check the label of each variant.
| Concern | What to check | Who this matters to |
|---|---|---|
| Opened-pack leftovers | Check the pack's serving guidance and opened-life instructions against your next few desserts. | If custard is an occasional treat, I want to know I can finish an opened tin rather than discard the rest. About 42% of consumers put avoiding opened-pack waste first. |
| Cupboard quantity | Check whether the listing is for one tin or several, the weight of each pack and the date marking when it arrives. | When I serve custard regularly, I would rather open one tin at a time and keep the others unopened for later. Keeping a useful cupboard supply is the primary need for about 33% of consumers. |
| Ingredients and serving method | Read the milk-allergen declaration and nutrition per 100g; check the directions before heating. | If a household member needs a particular ingredient or preparation choice, the exact variant matters more to me than the number of tins. About 25% of consumers make dietary or recipe fit their first concern. |
A 1kg carton offers more servings per opened pack, which can be awkward if custard is only served occasionally. Tesco Groceries describes its Ambrosia 1kg carton as eight servings; the checked tin and carton instructions set a three-day refrigerated use period after opening.
Choose a pack size around desserts you actually plan to serve within the stated opened life. Several unopened 400g tins let you open the next pack when you need it.
The checked Tesco and ASDA directions require custard to be removed from the tin before microwave heating. ASDA also instructs shoppers not to reheat its product.
Follow the preparation directions on the specific pack and use a suitable separate container when heating.
The checked Tesco, ASDA and Ambrosia custards contain milk, even where a product is described as suitable for vegetarians.
Check the ingredient list and allergen declaration on the exact pack, particularly when switching flavours or buying several at once.
Tesco Groceries lists Ambrosia 400g custard tin variants and a 1kg carton, giving shoppers different pack sizes and recipes to compare.
Tesco Groceries lists a 400g ready-to-serve own-label tin with half a can as its serving basis.
ASDA Groceries lists Creamy Custard as a 400g ready-to-serve tin with two suggested servings.
These ready-to-serve 400g tins suit shoppers who want to plan servings one opened can at a time. For a cupboard stock-up, check the quantity offered on the product page before ordering.

A strawberry-flavoured ready-to-serve tin if that flavour suits your planned desserts. It can be served hot or cold and contains milk; transfer remaining custard from the can, refrigerate it and use it within three days.
Use the serving guidance on the tin as a planning aid rather than a fixed portion rule. Tesco Groceries and ASDA Groceries show a half-can basis for their checked 400g custards, while the checked Ambrosia Devon Custard listing uses a 130g portion.
Follow the exact pack's directions. The checked Tesco, ASDA and Ambrosia listings instruct shoppers to remove unused custard from the can, cover and refrigerate it, and use it within three days. Food Standards Scotland advises checking food labels for the appropriate storage instructions.
No. The checked Tesco, ASDA and Ambrosia custards contain milk. Check the ingredient and allergen information on the physical pack each time, including when choosing a different flavour.
No. GOV.UK food guidance explains that a best-before date concerns quality rather than safety; it does not extend a product's opened-pack use period. Check the date and storage directions on your unopened pack, then follow its separate instructions once opened.
