Sugar-priority dessert shoppers
If the pack needs to make a reduced-sugar or no-added-sugar claim, you may be willing to choose a carton or instant mix instead of a tin. The Tesco Groceries and Sainsbury's listings show why the format matters.
Who is choosing?
Tin-first cupboard shoppers
If you want a ready-to-eat 400g can to serve with a pudding, check its sugar information separately. Tesco Groceries and Sainsbury's list an Ambrosia low-fat can, but its low-fat wording is not a reduced-sugar claim.
Made-to-order custard shoppers
If you are happy to prepare custard just before serving, a no-added-sugar instant mix is worth checking. Tesco Groceries lists one made with boiling water; its ingredients and preparation differ from a ready-to-eat tin.
What matters when buying?
Decide whether the sugar claim, the ready-to-eat tin or making custard to order matters most; those choices lead to different packs for the same dinner.
| Concern | What to check | Who this matters to |
|---|---|---|
| Sugar claim | Read the exact claim and its comparator. Compare sugars per 100g or on the same serving basis. | If I want a stated sugar reduction with dessert, I would accept a carton rather than assume a low-fat tin meets that need. About 42% of consumers put a sugar-related claim first. |
| Ready-to-eat tin | Confirm the pack is a can and ready to serve; check its size and heating directions. | When I need custard I can open and serve with pudding, a tin matters more to me than a reduced-sugar claim. Roughly 33% of consumers prioritise that ready-to-eat format. |
| Preparation and ingredients | Check how to prepare the mix, its sweetener and highlighted allergens, and the nutrition basis for prepared custard. | I am willing to make custard just before dinner, provided the ingredients suit everyone being served. Around 25% of consumers put that made-to-order choice first. |
What is easy to overlook?
-
Reading “low fat” as “reduced sugar”
The Ambrosia 400g can listed by Sainsbury's is labelled low fat; Tesco Groceries attaches its explicit 30% lower-sugar comparison to an Ambrosia Light carton.
If sugar reduction is your requirement, check the claim on the exact pack and compare sugars using the same nutrition basis.

Treating instant mix like ready-to-eat custard
Tesco Groceries lists its No Added Sugar Instant Custard Mix as a product made with boiling water. Its listed ingredients include sucralose and milk ingredients.
Choose it only if preparation suits dinner, and read the current pack's ingredients and allergen declaration before serving.
-
Heating custard in its tin
Ambrosia's directions for its Deluxe Custard Can say to empty the contents into a saucepan, heat gently and stir frequently without boiling.
Transfer custard out of a metal tin and follow the heating instructions for the pack you bought.
-
Using an old ingredient list
Bird's notes that its food products may be reformulated, so an earlier ingredients or allergen list may differ from the pack in hand.
Check the current pack's ingredients, highlighted allergens and preparation instructions, particularly when serving someone who must avoid an ingredient.
Brands to consider
Ambrosia
Its relevant range includes a low-fat 400g can and ready-to-serve Light cartons, as listed by Tesco Groceries and Sainsbury's.
- Tesco Groceries describes its 500g Light carton as 30% lower in sugar and fat than Ambrosia Devon Custard and suitable for serving hot or cold.
- The checked 400g can carries a low-fat description, not that comparative reduced-sugar claim.
Tesco
Tesco Groceries lists both a ready-to-serve 400g custard and a separate No Added Sugar Instant Custard Mix.
- The instant mix offers a no-added-sugar claim for shoppers willing to make custard with boiling water.
- The mix contains sucralose and milk ingredients and is not a ready-to-eat tin.
Sainsbury's
Its custard range includes ready-to-eat and instant options alongside listed Ambrosia Light cartons.
- The different formats give shoppers a choice between serving custard straight from a pack and preparing it.
- Do not treat a product labelled “lighter” as reduced sugar without checking that product's own claim and nutrition table.
Bird's
Bird's lists custard powders, including instant varieties, for shoppers who prefer to prepare custard.
- Its powder range is relevant when making custard to order matters more than a ready-to-eat tin.
- Bird's advises checking the physical pack because formulations and nutrition or allergen information can change.
Joybuy custard selections
These selections cover two ways to serve ready-to-eat custard with dinner: a reduced-sugar Light carton when the claim takes priority, and a low-fat can when the tinned format matters more.

Ambrosia Light Devon Custard 1kg
Consider this ready-to-serve carton if a reduced-sugar claim matters more than buying a tin. Sainsbury's lists the 1kg Ambrosia Light carton as reduced sugar; check the exact pack claim and sugars per 100g when choosing it for dinner.
No image available
Ambrosia Low Fat Custard 400g
Consider this ready-to-eat can when keeping custard in a tin is the priority. Sainsbury's identifies the 400g can as low fat; check its current sugar information separately if a reduced-sugar claim is important.
Questions about custard
Does a tinned custard have the same reduced-sugar claim as Ambrosia Light?
Do not assume so. In the Tesco Groceries and Sainsbury's listings considered here, the explicit reduced-sugar wording applies to Ambrosia Light cartons, while the Ambrosia 400g can is described as low fat. Check the claim on any tin you are considering.
Does “low fat” mean “reduced sugar” on custard?
No: the claims describe different things. GOV.UK explains that nutrition claims such as “low fat” are subject to specific rules; for a sugar-first choice, read the product's own sugar claim and nutrition table rather than relying on its fat claim.
How should I heat custard from a can?
Follow the directions on your particular pack and transfer the custard out of the tin. For its Deluxe Custard Can, Ambrosia instructs shoppers to heat the contents gently in a saucepan, stirring frequently without boiling.
What should I check if someone being served must avoid milk?
Read the ingredients and highlighted allergens on the actual pack before serving. Tesco Groceries lists milk ingredients in its No Added Sugar Instant Custard Mix, and Bird's notes that product formulations can change.
