Occasional tea-time shoppers
If custard is a cupboard backup for cake, fruit or crumble, a 400g ready-to-serve tin avoids mixing custard from powder. Check how much you will use and how soon the remainder must be refrigerated and eaten.
Who is this for?
Households checking allergens
Read the current ingredient and allergen information before serving. The researched ambient tins from Ambrosia, Tesco, Asda and M&S list milk ingredients without listing egg in their displayed ingredients; separate chilled custards from Sainsbury's and M&S list egg yolks.
Nutrition-comparison shoppers
Compare sugars, fat and saturated fat per 100g, then look at the portion you intend to serve. Ambrosia's claim that its Light 400g can has 30% less sugar and fat is a comparison with Ambrosia Devon Custard, not with every custard.
What matters when choosing?
| Concern | What to check | Who this matters to |
|---|---|---|
| Pack fit | Check whether it is ready to serve, its stated servings and its storage instructions after opening. | For an occasional tea time, I want a cupboard pack without a large amount left over. About 33% of consumers put ready-to-serve convenience and pack fit first. |
| Allergens | Read the selected pack's current ingredient list and allergen declaration; do not infer egg content from the word custard. | When an ingredient must be avoided, I need to know what is in this particular pack before serving it. Allergen certainty is the primary concern for about 25% of consumers. |
| Sugars and fat | Compare values per 100g and check the serving size and the named product behind any comparison claim. | If I am choosing between ready-to-serve options, I want to compare their labels on the same basis. About 25% of consumers chiefly look for a lower-sugar or lower-fat option. |
| Usable servings | Match the pack's servings to your plans and its refrigerated use period after opening. | With several desserts planned, I want enough custard without leaving an opened pack unused past its label instructions. Avoiding unused custard comes first for about 17% of consumers. |
Common buying mistakes
-
Assuming custard always contains egg—or never does
The displayed ingredients for the researched ambient tins list milk, while separate chilled luxury custards from Sainsbury's and M&S list egg yolks. The product and recipe matter more than the category name.
Check the exact pack's current ingredients and allergen declaration before serving, particularly when someone needs to avoid milk or egg.
-
Opening a large pack for one dessert
A larger ambient pack can leave several servings to refrigerate. The researched Sainsbury's 500g and 1kg cartons instruct use within three days of opening; the M&S 400g tin states two days.
Choose a pack size that fits the servings you have planned and follow its own opened-pack instructions.
Custard left beyond the stated refrigerated use period may have to be discarded.
-
Comparing nutrition by the whole pack
Serving bases differ: Ambrosia describes 130g portions for its standard 400g can, while Sainsbury's cartons use 125g servings. A pack-to-pack comparison does not hold portion size constant.
Start with the per-100g figures, then check the amount you intend to serve.
-
Relying on an old product listing
Ingredients, nutrition information and allergen declarations can change with a recipe or packaging update.
Use listings to narrow your choice, but read the current physical pack before purchase and serving.
Brands and product lines to compare

- Premier Foodservice describes hot or cold serving and a 24-month unopened shelf life for this product.

Sainsbury's

- Both researched cartons contain milk and require refrigeration and use within three days of opening. A separate chilled custard in its range lists egg yolk.
Asda
The researched Just Essentials and Creamy Custard options are distinct 400g ambient tins.
- Asda lists two servings for the Just Essentials tin and provides per-100g nutrition information for comparing the two products.
- The Creamy Custard variant has different fat and saturated fat values from Just Essentials. Check the chosen tin's ingredients and opened-pack instructions.

Questions about buying and serving
Does tinned custard always contain egg?
No. The displayed ingredient lists for the researched ambient tins from Ambrosia, Tesco, Asda and M&S include milk but do not list egg. Separate chilled custards from Sainsbury's and M&S explicitly list egg yolks. Check the current label of the exact product you plan to serve.
What should I check on a custard's allergen label?
Check the ingredient list and emphasised allergens on the particular prepacked product. GOV.UK guidance for England, Wales and Northern Ireland and Food Standards Scotland guidance for Scotland describe allergen information requirements; neither a product name nor a previous pack replaces the current label.
Can I microwave custard in its tin?
Do not put the tin in the microwave. The researched Tesco and Sainsbury's heating instructions call for custard to be transferred to a suitable non-metallic container before microwaving. Follow the chosen pack's heating and stirring directions.
How long can I keep custard after opening?
Follow the period on the exact pack and refrigerate it as instructed. The researched ambient products from Ambrosia, Tesco, Asda and Sainsbury's state use within three days after opening, while the researched M&S 400g tin states two days.
