Small-portion shoppers
If custard is a separate pudding after breakfast, a 400g can may suit two servings. Sainsbury's describes its Stamford Street Co. 400g can as serving two; check the serving information on any other tin.
Who might choose a tin
Low Fat variant shoppers
If you specifically want a ready-to-serve tin labelled Low Fat, Joybuy lists Ambrosia Low Fat Custard 400g as containing less than 3% fat. Check the exact can's nutrition and allergen information before serving.
Recipe-led dessert planners
If the custard will accompany a separate sweet course, the ingredients may guide your choice. M&S describes its 400g Silky Smooth Custard as made with whole milk and lists cream among its ingredients.
What matters when choosing
Decide how much custard you will serve, then compare the formulation and the instructions for any leftovers.
| Concern | What to check | Who this matters to |
|---|---|---|
| Portion and leftovers | Check the pack quantity and its instructions for refrigeration and use after opening. | If I am serving a small pudding course, I want an amount I can use within the pack's stated window. About 44% of consumers put portion fit first. |
| Formulation and allergens | Confirm the exact variant, read its per-100g nutrition panel and check the milk declaration. | If I want the Low Fat variant, I still need to know whether it contains milk. A lower-fat formulation is the primary concern for about 33% of consumers. |
| Recipe and serving style | Read the ingredients and the pack's directions for serving it cold or warming it. | For a separate sweet course, I may care most about whether the ingredients and serving style suit my dessert. About 23% of consumers prioritise that choice. |
Checks before serving
-
Assuming Low Fat means milk-free
Ambrosia's standard and Low Fat 400g custards both declare milk. The formulation name does not establish allergen suitability.
Read the ingredients and allergen declaration on the exact can, particularly when serving someone with a milk allergy.
-
Assuming every opened pack keeps for the same time
Storage directions are product-specific. Tesco's Ready To Serve Custard 400g instructions say to transfer unused contents to a non-metallic container, refrigerate them and consume them within three days.
Check the chosen pack before opening it and plan any remaining custard around its own directions.
A pack left unused beyond its stated opened-pack period may have to be discarded.

Common questions
Does custard belong on the full Scottish breakfast plate?
Treat custard as an optional, separate sweet course rather than a sauce for the savoury breakfast. The custard product descriptions position it as a dessert accompaniment, topping or snack.
Should I choose a tin, carton or powder?
Choose a ready-to-serve tin when its quantity fits your sweet course and you do not want to make custard. Bird's powder requires preparation, while the ready-to-serve Bird's carton listed by Brakes contains 1kg; check how much you will use after opening.
Can I warm ready-to-serve custard?
Check the heating directions on the exact product before warming it. Follow its instructions for the container, method and stirring rather than assuming every tin or carton has the same directions.
How should I keep custard left in an opened tin?
Follow that tin's instructions rather than applying one storage period to every product. Tesco, for example, says to transfer unused Ready To Serve Custard to a non-metallic container, cover and refrigerate it, and consume it within three days.
Is one of these tins suitable for someone with a milk allergy?
Do not assume so: the standard and Low Fat Ambrosia 400g listings declare milk, and M&S describes its 400g custard as made with whole milk. Check the ingredients and allergen declaration on the physical pack of the exact product you intend to serve.
