Convenience-focused sharers
If this is your first food shop, an ambient, ready-to-serve tin lets you keep custard in the cupboard before opening and serve it cold or warmed without making it from scratch.
Who these options suit
Portion planners
Check how many servings the pack states and whether you can finish any leftovers after opening. A larger pack is not automatically a better fit for one shared pudding.
Ingredient-conscious shoppers
Compare the exact recipes and nutrition labels rather than treating standard, lighter, powdered and chilled custard as interchangeable. Check the current pack’s allergen statement.
What to check when buying
Start with how you will serve the custard and store it after opening, then compare portions and the exact recipe.
| Concern | What to check | Who this matters to |
|---|---|---|
| Convenience and cupboard storage | Look for ready-to-serve instructions and unopened storage directions; check how to warm the custard if needed. | If I want a shared dessert without buying milk or preparing custard, an ambient tin fits that priority. About 31% of consumers would put immediate convenience first. |
| Portions and leftovers | Compare stated servings with your planned portions and read the opened-pack storage instructions. | When only one pudding is planned, I want a pack I can realistically finish after opening. For about 25% of consumers, portion planning would be the primary concern. |
| Fat and sugar values | Compare sugars and saturated fat per 100g on the exact variants; check the stated serving size too. | If I am choosing between standard and lighter ready-made recipes, I want to compare their labels rather than rely on the product name. About 19% of consumers would make that comparison their first priority. |
| Recipe or preparation control | Decide whether you want a chilled recipe or are willing to make powder with milk, sugar and heat; check storage and allergens. | I might prefer the ingredients of a chilled custard, or want to adjust custard I make from powder, even though either choice changes how I shop and prepare it. Recipe or preparation control would come first for about 25% of consumers. |
Avoidable buying mistakes
-
Putting every custard in the cupboard
The ambient tins checked can be stored in a cool, dry place before opening. The M&S chilled custard instead needs refrigeration at 0°C to +5°C and has a use-by date.
Choose your storage space before buying, and follow the directions on the exact pack.
-
Choosing a larger pack without planning leftovers
The Ambrosia 750g pack listed by ASDA states six portions, but its opened contents must be refrigerated and used within three days.
Match the pack to the desserts you expect to serve during its stated opened life.
Unused custard may go to waste if the pack is too large for those occasions.
-
Heating custard in the tin
The checked microwave instructions call for transferring custard to a suitable container; heating and reheating directions vary by product.
Empty it into a microwave-safe bowl or use a saucepan, then follow the pack’s heating and stirring instructions.
-
Assuming another format avoids the same allergens
The ready-to-serve tins checked contain milk. Bird's powder says it may contain milk, while the checked M&S chilled custard contains milk and egg and carries nut and peanut suitability warnings.
For an allergy, read the current ingredients and allergen statement of the exact product rather than substituting by format alone.
Brands and ranges to consider
Ambrosia
Ambient ready-to-serve custard includes the checked 400g Devon tin, a 750g pack and a 400g Light variant.
- ASDA Groceries lists three portions for the standard 400g tin and six for the 750g pack.
- The checked products contain milk and require refrigeration and use within three days of opening.
Bird's
Custard powder is an option if you want to make a batch rather than open ready-to-serve custard.
- Bird's recipe uses powder, sugar and milk and makes four servings.
- It needs preparation; the powder may contain milk, and Bird's says prepared custard should be refrigerated and treated as fresh food.
ASDA
The checked own-label ambient choices include 400g Creamy Custard and Just Essentials custard tins.
- ASDA Groceries states two servings for each of those checked 400g tins.
- Both contain milk. Their opened contents must be transferred to a non-metallic container, refrigerated and used within three days.
M&S
The checked 500g Madagascan vanilla custard is a chilled alternative made with milk, cream and egg yolks, not a cupboard-stored tin.
- Its listed recipe gives shoppers a distinct ingredient choice from the ambient tins checked.
- M&S specifies refrigeration at 0°C to +5°C and a use-by date. The product contains milk and egg, and its page says it is unsuitable for people with nut or peanut allergy.

Questions about buying and serving custard
Can unopened tinned custard go in a cupboard?
The ambient tins checked can be stored unopened in a cool, dry place. Check the exact product: the M&S chilled custard instead needs refrigeration at 0°C to +5°C and has a use-by date.
What should I do with custard left after sharing?
Follow the exact pack’s storage instructions. The checked Ambrosia and ASDA tins call for refrigeration and use within three days of opening; ASDA’s own-label instructions also say to transfer unused contents to a covered, non-metallic container.
Can I microwave tinned custard in its can?
No. Transfer it to a microwave-safe container and follow the pack’s heating, stirring and reheating directions.
How do I check tinned custard for milk allergens?
Read the current ingredients and allergen statement on the exact pack; the ready-to-serve custards checked contain milk. GOV.UK identifies milk as an allergen that must be declared when present in prepacked food.
How can I compare standard and lighter custard?
Compare the exact variants’ values per 100g and their stated portion sizes, rather than relying on the front label. ASDA Groceries lists 7.4g sugars and 1.0g saturated fat per 100g for the checked Ambrosia Light 400g tin, against 10.6g sugars and 1.5g saturated fat for the checked standard Ambrosia Devon Custard 400g tin. The NHS notes that a manufacturer’s stated portion may differ from the amount you serve.
