Choose individual custard pots if each guest needs a separate serving: Ambrosia labels its 400g tin as three portions, not one. A ready-to-serve tin or larger pack suits custard poured over a shared pudding, provided you can portion it and store any leftovers. Powder is another option if you want to make a batch and have time to prepare it.
Who each format suits
Hosts serving one dessert per guest
If guests will pick up their own custard at a buffet or children’s table, an individual pot gives each person a defined serving without portioning from an opened pack. Ambrosia makes a 150g pot; its 400g tin is labelled as three portions.
Hosts serving a shared pudding
When custard will be poured over cake, crumble or fruit, you can divide a ready-to-serve pack as you serve. Ambrosia’s 400g tin is labelled as three portions, while Sainsbury’s describes its 500g ready-to-eat pack as four servings.
Hosts making a larger batch
Powder suits a host who has time and equipment to prepare custard rather than open ready-to-serve packs. Bird’s describes its 350g powder pack as containing 40 portions; making it up requires milk, sugar, heating and stirring.
What matters when choosing
Decide whether custard is a separate serving for each guest or something to add to a shared pudding. Then plan quantities and preparation around that choice.
| Concern |
What to check |
Who this matters to |
| Individual servings |
Check the pack’s portion count. Choose a labelled single pot if each guest needs their own serving; a 400g Ambrosia tin is labelled as three portions. |
If guests will help themselves, I want each person to take a defined portion without waiting for custard to be served. About 42% of consumers put individual service first. |
| Shared-dessert quantities |
Check stated servings and decide how much custard to offer with each pudding portion. Compare pack formats on the same quantity basis if cost matters. |
For a pudding served in bowls, I need enough custard to go round without opening a separate pot for everyone. Roughly 33% of consumers prioritise shared serving. |
| Ingredients and preparation |
Read the current allergen and nutrition labels. If choosing powder, check what milk, sugar and preparation steps the finished custard requires. |
With an ingredient requirement or a recipe to adjust, I need to know what will be in the custard before it reaches the table. Around 25% of consumers put ingredient checks or preparation control first. |
Party-planning pitfalls
-
Counting a small tin as one guest’s portion
Ambrosia’s 400g tin is labelled as three portions, whereas its individual pot contains 150g. Pack size alone does not tell you whether a product is intended for one person.
Count guests, then decide whether custard is a topping or a separate dessert. Use individual pots for defined guest portions, or plan how you will divide a shared pack.
-
Choosing a larger pack without a serving plan
A communal pack still needs to be opened and portioned, and any remainder needs appropriate storage. Individual pots avoid that serving step but are not tins.
Match the format to how guests will eat dessert, rather than choosing by pack size alone.
-
Leaving opened custard out throughout the party
Ambrosia instructs consumers to remove leftovers from its 400g can, refrigerate them and use them within three days. Food Standards Scotland advises against leaving party food out for more than four hours.
Serve what you expect to use, keep unopened backup packs according to their labels, and follow the opened pack’s storage instructions for leftovers.
-
Relying on a product name for dietary suitability
Names such as Light or Low Fat do not establish whether custard meets a guest’s ingredient requirements. Powder also has to be assessed as the finished recipe, including anything added during preparation.
Check the current pack’s ingredients and allergen statement before serving. For a nutrition comparison, use the stated values on a consistent per-serving or per-100g basis.
Brands to consider
Ambrosia
Ambrosia has both a ready-to-serve 400g tin and 150g individual custard pots.
- Its 400g Devon Custard tin is labelled as three portions and can be served hot or cold.
- The tin is not a sealed serving for each guest; its 150g pot is a different format.
Tesco
Tesco lists an own-label 400g ready-to-serve custard for shared serving.
- The ready-to-serve format avoids making custard from powder.
- A shared pack still needs portioning; check its own label rather than assuming it matches another brand’s ingredients or servings.
Sainsbury's
Sainsbury’s has a 500g ready-to-eat custard pack for shared service, rather than an individual pot or confirmed tin.
- Sainsbury’s labels the 500g pack as four servings and says it can be served hot or cold.
- Its instructions call for refrigeration after opening and consumption within three days.
Bird's
Bird’s custard powder is a make-from-powder option for a batch prepared by the host.
- Bird’s states that its 350g Original Custard Powder pack contains 40 portions.
- It is neither ready to serve nor individually portioned; preparation requires milk, sugar, heating and stirring.

Questions about serving custard
Is a 400g tin of custard one individual portion?
No: Ambrosia labels its 400g Devon Custard can as three portions. If each guest needs a separate sealed serving, its 150g pot is an individual format; check how many guests you are serving before choosing pack quantities.
Can I serve ready-to-serve custard cold?
Ambrosia says its Devon Custard can and 150g pot can be served hot or cold. If you prefer it warm, follow the instructions for the particular pack and transfer canned custard to a suitable vessel before heating.
What should I do with custard left in an opened tin?
For Ambrosia’s 400g can, remove the remaining custard from the can, refrigerate it and consume it within three days, as Ambrosia instructs. Follow the label of any other product you use rather than applying that period to every pack.
Can I serve these custards to someone with a milk allergy?
Do not assume that a ready-made custard or powder is suitable. The Ambrosia can and pot list milk-derived ingredients, and Bird’s powder carries a may-contain-milk statement. Check the exact current pack and any ingredients added during preparation before serving.
