Cupboard-first shoppers
If custard is an occasional sweet finish to a breakfast gathering, an ambient ready-to-serve pack can wait unopened in the cupboard. Check the pack’s storage instructions before treating it as a cupboard item.
Who this choice suits
Nutrition-label comparers
If you are choosing between standard and light-labelled custard, compare sugars and fat per 100g on the current packs. Ambrosia’s stated comparison for its light can is against Ambrosia Devon Custard, not every custard on the shelf.
Pack-size planners
For a sweet course shared by several people, compare pack size and stated servings with what you expect to use. Opened-product storage matters too: Ambrosia instructs shoppers to refrigerate leftovers from its verified cans and use them within three days.
What to check when buying
| Concern | What to check | Who this matters to |
|---|---|---|
| Cupboard convenience | Confirm unopened ambient storage and whether the custard is ready to serve. | If I am serving a sweet course after breakfast, I want custard ready without mixing powder; about 38% of consumers put cupboard-ready convenience first. |
| Nutrition label | Compare sugars and fat per 100g, and read the named comparator behind a light claim. | For a light-labelled tin, I want to judge the per-100g figures rather than the word “light”; about 25% of consumers put label comparison first. |
| Pack size and leftovers | Check the pack weight, stated servings and instructions for storing it after opening. | When several people will share a pudding, I need enough custard without leaving more than I can use after opening; for about 25% of consumers, pack size and leftovers are the primary concern. |
| Made-to-order preparation | Read the powder’s recipe for required ingredients and heating steps. | If I prefer to make custard when it is needed, I can allow for ingredients and heating; about 12% of consumers put made-to-order preparation first. |
Buying pitfalls
-
Assuming every custard pack belongs in the cupboard
Ambrosia’s verified cans have cool, dry storage instructions before opening. The Sainsbury’s and M&S chilled examples require refrigeration, so they do not serve the same unopened storecupboard plan.
Read the storage directions on the exact pack before adding it to a cupboard shopping list.
-
Taking “light” to mean milk-free
Ambrosia compares its light can with its standard Devon Custard for fat and sugar, but both verified cans contain milk. The relative claim does not settle an allergen or dietary decision.
Check the current allergen declaration and compare the per-100g nutrition panels for the products you are considering.
-
Choosing a pack without checking size or availability
A product listing alone does not establish that the pack is available for your shop. Pack sizes also differ, which affects how much custard you will have to use after opening.
Confirm current availability and choose a size that fits the number of servings you plan to make.
-
Leaving opened custard in its can
Ambrosia directs shoppers to remove leftovers from its verified cans, refrigerate them and consume them within three days. Bird’s says made-up custard should be refrigerated and treated as fresh food.
Follow the instructions for your pack and plan when you will use any leftovers.
Unused leftovers may be wasted if they cannot be eaten within the stated storage period.
Brands and product lines to consider
Ambrosia
Ambrosia offers standard and light 400g ready-to-serve custard cans for ambient storage before opening.
- Ambrosia states that its light can has 30% less fat and 30% less sugar than Ambrosia Devon Custard.
- Both verified cans contain milk. Ambrosia instructs shoppers to refrigerate leftovers and use them within three days.
Bird’s
Bird’s Original Custard Powder is a cupboard-stored option for making custard, not a ready-to-serve tin.
- It suits a plan to prepare custard when it is needed.
- The verified preparation instructions require milk, sugar and heating; made-up custard must be refrigerated and treated as fresh food.
Tesco
Tesco’s tinned-custard category listed a Tesco Ready To Serve Custard 400g alongside branded products.
- The listing offers an own-label pack size to consider alongside other ready-to-serve options.
- Check the exact pack for its ingredients, allergens and storage directions before choosing it.
Asda
Asda’s 30% Less Fat Custard 500g is an ambient, ready-to-serve carton.
- Asda states that its fat comparison is against its standard equivalent.
- It contains milk and is a carton rather than a tin.
Sainsbury’s
Sainsbury’s Taste the Difference Vanilla Custard 500g is a chilled alternative made with cream and egg yolk.
- Its recipe offers a different ingredient choice from the ambient cans discussed here.
- It requires refrigeration and use-by-date handling, so it does not meet an unopened cupboard-storage need.
M&S
M&S Madagascan Vanilla Luxury Custard is a chilled product made with Channel Island milk, cream and egg yolks.
- It provides an egg-and-cream recipe to consider when chilled storage suits the plan.
- M&S specifies refrigeration at 0°C to +5°C; the product declares milk and egg and is marked unsuitable for people with nut or peanut allergy.

Frequently asked questions
Does custard belong in a Full English breakfast?
Plan custard as an optional sweet course after the savoury breakfast, rather than as an ingredient in it. Ambrosia and Bird’s present the custards discussed here as products for desserts, puddings or snacks.
Can unopened tinned custard stay in the cupboard?
Ambrosia instructs shoppers to store its verified 400g cans unopened in a cool, dry place. Check the instructions on the exact pack, particularly if you are considering a chilled product or a different format.
How should I store custard left in an opened can?
For the verified Ambrosia cans, remove the remaining custard from the can, refrigerate it and consume it within three days. Follow the individual pack rather than applying that period to every brand or format.
Can I heat custard in its original can?
Ambrosia’s directions call for emptying the custard into a saucepan or microwaveable container before heating, then heating it gently without boiling. Follow the heating directions for the particular product you choose.
Is this custard suitable for someone with a milk allergy?
Do not assume it is: the verified Ambrosia cans and Asda reduced-fat custard contain milk. Check the current allergen declaration for the exact product and variant before serving it.
