Choose a 1 kg ready-to-serve tub when several people will share dessert and you can use any leftovers within the pack’s refrigerated storage period. For fewer servings, compare 400 g cans; powder takes preparation but lets you adjust the milk and consistency. Check the allergen declaration on the exact product rather than assuming every custard contains egg.
If custard is going alongside a pudding for several people, start with the stated servings, not just the pack weight. Joybuy describes its Ambrosia Devon Custard 1 kg tub as eight portions; Ocado labels the M&S ambient 400 g can as two servings.
If a child or guest has an allergy, check the exact pack before serving. The Joybuy listing for Ambrosia Devon Custard 400 g names milk as an allergen, while Ocado’s listing for a different, chilled M&S vanilla custard names egg yolk and milk and warns that it may contain nuts and peanuts.
If tea time needs to be served quickly, a ready-to-serve pack avoids making custard from powder. If fat or sugars are part of the choice, compare the nutrition panels per 100 g and check the portion shown on each pack.
| Concern | What to check | Who this matters to |
|---|---|---|
| Servings and leftovers | Compare labelled servings with the number of bowls needed, then read the opened-pack storage instruction. | If custard is for several children and adults, I need enough for everyone without leaving more than we can use in time. About 42% of consumers put serving capacity and manageable leftovers first. |
| Allergens | Read the exact pack’s current ingredients, allergen declaration and any precautionary wording before serving. | When someone at tea time has an allergy, I need to know whether this particular custard is suitable, rather than relying on its name or brand. Allergen certainty comes first for about 33% of consumers. |
| Preparation and nutrition | Check whether the custard is ready to serve or needs cooking; compare fat and sugars per 100 g and the labelled portion. | On a busy afternoon, I want to weigh up serving time against the nutrition information that matters to my household. About 25% of consumers make that their primary concern. |
Recipes differ even within a brand’s range. Ocado lists egg yolk in M&S chilled Madagascan vanilla custard, which is a different product from its ambient 400 g can.
For an allergy-sensitive child or guest, read the ingredients, allergen declaration and precautionary wording on the exact pack you intend to serve.
A sharing tub may leave custard after the first dessert. The Joybuy listing for Ambrosia Devon Custard 1 kg says to refrigerate it after opening and use it within three days; Ocado gives two days for its M&S ambient 400 g can.
Check the period on your chosen pack and pick a size you can use within it.
Custard left beyond its stated opened-pack period may have to be discarded.

Consider this ready-to-serve 1 kg pack when custard will be shared across several bowls. It contains milk, so it is unsuitable where milk must be avoided; check the current pack’s full allergen declaration and opened-pack storage instruction.

Consider this smaller ready-to-serve can when a 1 kg pack would leave too much custard. Tesco lists this variant as less than 3% fat, with 2.0 g fat and 7.4 g sugars per 100 g. It contains milk; check the current pack for its full allergen declaration and stated servings.
Do not assume egg is present or absent from the word “custard”. The Joybuy listing for Ambrosia Devon Custard 400 g identifies milk as an allergen, while Ocado lists egg yolk in a different, chilled M&S vanilla custard. For an allergy-sensitive serving, check the exact pack’s ingredients and allergen wording.

The Ambrosia and M&S ready-to-serve products described here can be served hot or cold. If heating, follow the instructions for the exact product rather than assuming cans, tubs and chilled custard have the same directions.
Follow the chosen pack’s refrigeration and use-by-opening instructions. Joybuy gives three days after opening for Ambrosia Devon Custard 1 kg, while Ocado gives two days for the M&S ambient 400 g can; those periods should not be applied to other custards.
Powder can make custard for the same dessert, but it does not offer the same immediate serving convenience. Bird’s powder requires milk, sugar and heating, so choose it when you have time and equipment to prepare it.
