Families checking allergens
Parents and carers choosing custard for a child with an allergy need to read the current pack’s ingredients and allergen declaration. Egg should not be assumed to be present in every custard recipe.
Who is this for?
Households sharing a dessert
A 400g ready-to-serve tin is worth considering when several portions are needed at tea time, rather than one individual snack pot.
Shoppers comparing recipes
Standard, low-fat and deluxe labels point to different recipes. The nutrition panel helps shoppers compare the figures that matter to their household on a consistent per-100g basis.
What matters when choosing?
For a child’s tea time, settle allergen suitability before comparing recipes, then plan how much of the tin you intend to serve.
| Concern | What to check | Who this matters to |
|---|---|---|
| Allergen suitability | Read the exact pack’s current ingredients and emphasised allergens; do not assume all custard contains egg. | If a child has an allergy, I need to establish what is in this recipe before flavour or convenience matters. About 40% of consumers put current allergen suitability first. |
| Nutrition profile | Compare energy, sugars, fat and saturates per 100g, then consider the amount to be served. | When choosing between low-fat and deluxe recipes, I want the figures for the food I will actually portion out. About 30% of consumers make the nutrition profile their primary concern. |
| Portions and preparation | Check the stated servings, heating directions and instructions for the remainder after opening. | One tin needs to work for our tea-time portions without an uncertain plan for what is left. Portioning and preparation come first for about 30% of consumers. |
Mistakes to avoid
-
Assuming every custard contains egg
ASDA Light Custard and Ambrosia Deluxe Custard declare milk, but the ingredients shown for those tins do not list egg. Other custard recipes can contain egg yolks.
Check the ingredients and allergen declaration on the exact current pack, especially when serving a child with an allergy.
-
Treating one tin as one child’s portion
ASDA suggests two servings for its 400g Light Custard; the Ambrosia Deluxe 400g listing states three portions.
Decide how much to serve and follow the pack’s directions for any custard left after opening.
Opening a tin for one portion can leave custard that needs storing and using within the pack’s stated period.
-
Reading “light” as sugar-free or allergen-free
ASDA Light Custard declares milk and lists 8.3g sugars per 100g. Its name alone does not answer either question.
Compare the exact nutrition panel and allergen declaration against the household’s needs.
-
Heating custard in the tin
Sainsbury’s instructions for its Stamford Street Co. 400g custard call for transferring it to a microwaveable dish and say not to reheat it once cooled.
Follow the heating directions for the product you buy; do not put a metal tin in the microwave.
Brands and nearby options
Ambrosia
Tesco and Sainsbury’s list several Ambrosia 400g custards, including standard, low-fat and deluxe variants.
- The variants allow a recipe-based choice within the 400g format.
- Ingredients, nutrition and allergens can differ by variant and change with reformulation; read the current pack.
Tesco
Tesco lists its own Ready To Serve Custard in a 400g format alongside branded tins.
- Its own-label product offers another 400g ready-to-serve option to compare.
- Check the product’s current ingredients, allergens and preparation directions before choosing it for a particular child.
Sainsbury’s
Sainsbury’s lists a 400g own-label custard, including a Stamford Street Co. product with hot-serving directions.
- The Stamford Street Co. directions explain how to transfer and heat the custard.
- Use the current pack for its complete allergen and nutrition details.
Asda
ASDA lists a 400g Light Custard with nutrition figures and a milk-allergen declaration.
- ASDA states 76 kcal and 1.6g fat per 100g for its Light Custard and suggests two servings per tin.
- The same listing declares milk and states 8.3g sugars per 100g; “light” does not mean allergen-free or sugar-free.
M&S
M&S lists a 400g Silky Smooth Custard made with whole milk.
- Its 400g size makes it relevant to a portion-planning comparison.
- Check its packaging format and current allergen label rather than assuming it is a direct substitute for a tin.
Bird’s
Bird’s appears in the custard aisle through products including instant powder sachets, which involve a different preparation choice.
- Powder sachets are relevant if preparing custard is acceptable instead of opening a ready-to-serve tin.
- Do not treat those sachets as the same format as a plain 400g ready-to-serve tin.

Common questions
Does every tin of custard contain egg?
No category-wide assumption is safe: the ingredients shown for ASDA Light Custard 400g and Ambrosia Deluxe Custard 400g do not list egg, while other custard recipes can contain egg yolks. Check the exact current pack for the child who will eat it.
Where should I check allergens on a prepacked custard?
Read the current pack’s ingredients and allergy information. GOV.UK guidance says that any of the 14 regulated allergens present in a prepacked food must be emphasised in its ingredients list; a retailer listing is not a substitute for checking the pack before serving.
Can I heat custard in its tin?
Do not microwave a metal tin. Sainsbury’s directions for its Stamford Street Co. 400g custard say to transfer it to a covered microwaveable dish, stir during heating, check that it is piping hot, leave it to stand for one minute and not reheat it once cooled. Follow the directions on the product you buy.
Is a 400g tin one serving for a child?
Do not treat the whole tin as a single child’s serving. ASDA suggests two servings for its 400g Light Custard, and the Ambrosia Deluxe 400g listing states three portions. Check your chosen pack’s serving and after-opening directions when planning what to do with the remainder.
