For an optional sweet course after a Full English breakfast, choose a 400g ready-to-serve tin if avoiding preparation is the priority. A light recipe gives you a product-specific sugar-and-fat comparison, while a cream-enriched recipe suits a preference for a richer dessert-style finish; neither changes the need to check portions, milk allergens and instructions for leftovers. One tin does not necessarily mean one portion.
If you want to serve custard after the savoury breakfast without mixing or cooking it from powder, a ready-to-serve tin can be served hot or cold. Plan for more than one portion from a 400g can and check how to store any remainder.
For a ready-to-serve sweet course, compare the per-100g labels rather than serving figures based on different portion sizes. Ambrosia states that its Light Devon Custard has 30% less sugar and fat than its standard Devon Custard; that claim names a specific comparator, not every custard.
If the custard is intended as a deliberate sweet finish, a cream-enriched recipe may match the flavour and texture you want. Tesco describes Ambrosia Deluxe as thick and creamy and lists higher fat, saturates and sugars per 100g than Ambrosia’s standard Devon Custard.
Decide whether serving convenience, the nutrition comparison or a cream-enriched recipe matters most, then check the exact tin’s portion and storage instructions.
| Concern | What to check | Who this matters to |
|---|---|---|
| Serving and leftovers | Look for “ready to serve”; check the labelled portion and instructions for opened custard. | If I want a sweet course ready without mixing, I also need a plan for what remains in the tin. About 50% of consumers put convenient serving and leftover handling first. |
| Sugars and fat | Compare sugars, fat and saturates per 100g, then consider the amount you intend to serve. | When adding custard to the occasion, I want to compare recipes on the same nutrition basis. Consumers making sugars and fat their primary concern account for about 30%. |
| Richer recipe | Check for a cream-enriched recipe and compare its per-100g nutrition with the standard tin. | For a dessert-style finish, I may care more about a cream-led recipe than choosing the standard version. Roughly 20% of consumers place that preference first. |
Bird's Original Custard Powder requires added milk and sugar and cooking, unlike a ready-to-serve tin.
If you do not want preparation on the day, check that the product says “ready to serve”.
The checked Ambrosia and Tesco ready-to-serve instructions call for transferring custard to a suitable container before microwave heating.
Empty it from the can and follow the heating and stirring directions on the pack.
Ambrosia gives a 130g portion for its standard tin, while Tesco presents nutrition for a 200g half-can serving. Figures per serving therefore describe different amounts.
Compare per-100g values first, then use the exact label to assess the amount you plan to pour.
A recipe or its allergen information can change, which matters particularly when someone needs to avoid milk.
Read the physical tin’s ingredients and allergen information each time you buy it.
Ambrosia’s 400g ready-to-serve cans include Devon Custard, Light Devon Custard and a cream-enriched Deluxe recipe.
Tesco lists a 400g own-label Ready To Serve Custard can that can be served hot or cold.
M&S lists Silky Smooth Custard in a 400g can made with whole milk.
Bird's Original Custard Powder is a make-up alternative, not a ready-to-serve single tin.
These 400g Ambrosia tins offer a standard recipe, a lower-fat variation and a strawberry-flavoured variation for an optional sweet course. Compare the individual labels before choosing a portion or serving them to someone avoiding milk.

A ready-to-serve standard custard for a sweet course, served hot or cold. The 400g can states three 130g portions; its listed sugars and fat are 10.6g and 2.9g per 100g. It contains milk. Transfer any remainder from the can, refrigerate it and use it within the stated three days.

A ready-to-serve option for comparing sugars and fat while keeping the same 400g tin format. The listing gives 7.4g sugars and 2.0g fat per 100g. It contains milk; check the pack’s portion basis and transfer leftovers from the can, refrigerating and using them within the stated three days.

A ready-to-serve strawberry-flavoured variation if you want a different sweet-course flavour; the 400g custard can be served hot or cold. It contains milk. Check the pack for portions and heating directions, and follow its instruction to refrigerate remaining custard and use it within three days.
Yes. The checked Ambrosia and Tesco ready-to-serve products can be served hot or cold. If heating them, follow the pack directions and transfer the custard out of its metal can first.
There is no single portion size across these products: Ambrosia’s standard and light cans state three 130g portions, while Tesco uses a 200g half-can serving for its nutrition information. Check the exact tin against the amount you intend to serve each person.
Follow the instruction on your tin. Ambrosia’s checked standard and light cans say to remove the remainder from the can, refrigerate it and consume it within three days; M&S specifies refrigeration and use within two days for its checked 400g custard.
Do not assume so: the checked Ambrosia, Tesco and M&S ready-to-serve products identify milk ingredients or milk allergen information. Read the physical product label before serving, as ingredients can change. GOV.UK states that prepacked food containing any of the 14 regulated allergens must clearly label them.
Not when immediate serving is the priority. Bird's Original Custard Powder requires added milk and sugar followed by hob or microwave cooking; choose it instead if you want to make up the custard yourself and have time to prepare it.
