Sugar-first hosts
You want custard ready for guests but would rather compare the sugars figure per 100g than choose by front-of-pack wording alone.
Who is this for?
Tin-only convenience shoppers
You want a 400g tin that can be served cold or heated, without mixing custard while friends are visiting.
Flexible-format entertainers
You can consider a carton or prepare custard from powder if that better matches the number of guests and the preparation time available.
What matters when choosing?
Decide whether a ready-to-serve tin is essential, then compare sugars per 100g and the stated portions for the gathering.
| Concern | What to check | Who this matters to |
|---|---|---|
| Sugars, not just fat | Compare ‘of which sugars’ per 100g for custards in the same ready-to-serve state. Asda Groceries lists 7.4g for the Ambrosia Light tin and 10.6g for the standard Ambrosia tin; Tesco Groceries lists 11.3g for Tesco Reduced Fat Custard. | When choosing custard for friends, I want the sugars figure to guide me rather than a reduced-fat claim; about 42% of consumers put sugar comparison first. |
| Tin convenience | Check that the pack is a tin and ready to serve. The Ambrosia Light 400g can lists three 130g portions. | If friends are arriving soon, I want custard I can serve without mixing; for about 33% of consumers, a ready-to-serve tin is the main concern. |
| Servings and preparation | Check the stated portions and whether preparation is needed. The Ambrosia Light 500g carton lists four 125g servings; Tesco No Added Sugar Instant Custard Mix requires boiling water and whisking. | I need to know whether there is enough for everyone and whether I have time to make it; servings and preparation come first for about 25% of consumers. |
Buying pitfalls
-
Assuming reduced fat means reduced sugar
These claims concern different nutrients. Tesco Groceries lists 11.3g sugars per 100g for Tesco Reduced Fat Custard, while Asda Groceries lists 7.4g per 100g for the Ambrosia Light reduced-sugar tin.
Compare the sugars line per 100g on like-for-like prepared products; consider fat separately if it matters to your choice.
-
Treating cartons and powders as tins
A carton may be ready to serve but is not tinned. Tesco No Added Sugar Instant Custard Mix is a powder that needs boiling water and whisking.
Settle the pack-format question before comparing nutrition panels: if a ready-to-serve tin is essential, a carton or powder does not meet that requirement.
-
Overlooking allergens and leftovers
The Ambrosia Light 400g tin contains milk. Its instructions call for leftover custard to be transferred out of the can, refrigerated and consumed within three days.
Ask guests about milk allergies, check the current label and plan how many of the stated portions you will use.
Opening more custard than the group needs can leave portions that must be used within the stated storage period.
Brands to consider for these formats
Ambrosia
Its Light range includes a reduced-sugar 400g ready-to-serve tin, as well as cartons for shoppers who do not require a tin.
- Asda Groceries lists 7.4g sugars per 100g for the Light tin, against 10.6g per 100g for the standard Ambrosia 400g tin.
- The Light tin contains milk and states three 130g portions; check whether that covers the group.
Tesco
Its custards illustrate the difference between a reduced-fat ready-to-serve carton and a no-added-sugar instant mix.
- Tesco Groceries lists 5.7g sugars per 100g for its No Added Sugar Instant Custard Mix when prepared as directed.
- The mix contains sucralose and needs boiling water; Tesco Reduced Fat Custard lists 11.3g sugars per 100g and is not a tin.
Bird's
Its custard powder is an option for shoppers willing to make custard rather than serve it from a tin.
- Powder offers a preparation-based format instead of a ready-to-serve pack.
- Joybuy's Bird's Custard Powder product information says to refrigerate it once made up and treat it as fresh food; it does not meet a ready-to-serve tin requirement.
Joybuy product selections
These Ambrosia options cover a 400g custard can for tin-focused shoppers and a larger 1kg choice if a tin is not essential. Check the current pack when an explicit reduced-sugar claim matters: the can's Joybuy product name says low fat.

Common questions

No. Tesco Groceries lists 11.3g sugars per 100g for Tesco Reduced Fat Custard, while Asda Groceries lists 7.4g per 100g for the Ambrosia Light reduced-sugar can. Compare the sugars line per 100g rather than treating a fat claim as a sugar claim.
Can Ambrosia Light custard from the 400g tin be served cold?

How many portions are stated on the Ambrosia Light 400g tin?
The tin states three 130g portions. Use that label figure to plan for the number of guests and what else you will serve.
Does the Ambrosia Light 400g tin contain milk?
Yes. Its allergen information states that it contains milk. Check the current label for any custard you intend to serve to someone with a milk allergy.
