Per-100g nutrition comparers
If fat and sugar both matter to your choice, compare the figures per 100g rather than relying on the word “light”. Ambrosia publishes figures on that basis for its light and standard 400g cans.
Who is this choice for?
Convenience-led grocery shoppers
A ready-to-serve can suits an order where you want custard without making it from powder. Ambrosia’s light can can be stored in a cool, dry place before opening and served hot or cold; leftovers need refrigeration.
Households checking milk ingredients
Ambrosia’s light custard contains milk. If an online order permits substitutions, inspect the label on the product actually delivered before serving it to anyone with a milk allergy.
What matters when choosing?
For a ready-to-serve tin ordered with groceries, compare nutrition on the same per-100g basis, then check that the pack format and delivered product meet your needs.
| Concern | What to check | Who this matters to |
|---|---|---|
| Fat and sugar | Compare fat and sugars per 100g on the exact product; do not mix per-serving and per-100g figures. | If I want less fat than in Ambrosia’s standard can, I also want to know how much sugar the light can contains. About 42% of consumers would make that nutrition comparison their primary concern. |
| Ready-to-serve format | Confirm that the product is a can, its net quantity and its serving and storage instructions. | For a dessert arriving with my groceries, I want a tin I can serve without preparing custard powder. Ready-to-serve convenience would come first for about 33% of consumers. |
| Exact product and leftovers | Check milk ingredients on the delivered pack, substitution settings and instructions for opened custard. | If the recipe changes in a substitution, or some custard remains after serving, I need to know what I have and how to store it. About 25% of consumers would prioritise those checks. |
What should you avoid?

Assuming “low fat” also means sugar-free or milk-free
Ambrosia lists 7.4g sugars per 100g for its light 400g can, and the product contains milk. Its lower-fat comparison with the standard can does not establish either of those other properties.
Read fat, saturates and sugars per 100g, and check the ingredients and allergen statement on the pack you receive.
-
Picking a lighter format that is not a tin
Custard listings can include cartons, pots and powder. Bird’s Original Custard Powder, for example, requires preparation rather than being a ready-to-serve tin.
Check the pack description and net quantity before ordering if a ready-to-serve can is essential.
-
Accepting a substitute without checking its label
A substitute may have different ingredients, nutrition values or packaging. Tesco says shoppers who allow substitutions can hand an unwanted substitute back at delivery or collection for a refund.
If the exact product matters, review your substitution choice and inspect any replacement before accepting it.
-
Keeping leftovers in the opened can
Ambrosia’s storage guidance says to remove remaining custard from the can, refrigerate it and consume it within three days of opening.
Transfer leftovers to a covered container and note when you opened the can.
Brands and retail options to consider
Ambrosia
Ambrosia offers light and standard ready-to-serve Devon Custard in 400g cans, allowing a within-brand nutrition comparison.
- Ambrosia lists 2.0g fat and 7.4g sugars per 100g for the light can, versus 2.9g fat and 10.6g sugars per 100g for its standard can.
- The light can contains milk; remaining custard needs refrigeration after opening and should be consumed within three days.
Tesco
Tesco’s custard category lists Ambrosia Low Fat Custard 400g alongside Tesco Ready To Serve Custard 400g.
- The listing lets shoppers consider two ready-to-serve cans in one grocery basket.
- Do not assume the Tesco own-label can has the same nutrition profile as the Ambrosia light can; compare their product labels.
Sainsbury’s
Sainsbury’s tinned-custard listing includes Ambrosia Low Fat Custard Can 400g, while its wider custard listings include other pack formats.
- Shoppers can check whether a listed lighter custard comes in the pack format they want.
- A carton or pot is not a direct substitute when a ready-to-serve tin is required.
Bird’s
Bird’s Original Custard Powder is an option for shoppers willing to make custard rather than buy it ready to serve.
- The powder listed in Tesco’s custard category is not a ready-to-serve low-fat tin; check the finished product’s ingredients and nutrition rather than treating formats as equivalent.

Questions about buying and serving
Does low-fat tinned custard also have less sugar?
Ambrosia’s light 400g can has less sugar per 100g than its standard Devon Custard can, but it is not sugar-free. Ambrosia lists 7.4g versus 10.6g sugars per 100g, respectively; compare the label of any other custard separately.
Can I serve Ambrosia’s light custard without preparing it?
Yes. Ambrosia’s light custard is ready to serve hot or cold. If you heat it, transfer it from the can and follow the pack’s hob or microwave instructions.
How should I store custard left in a 400g can?
For Ambrosia’s light can, move the remaining custard out of the can, refrigerate it and consume it within three days of opening. Store the unopened can in a cool, dry place.
Is Ambrosia Low Fat Custard suitable for someone with a milk allergy?
No. Ambrosia’s light custard identifies milk as an allergen and lists milk-derived ingredients. Check the label on the pack delivered, particularly if your order has been substituted.
What if Tesco delivers a custard substitute I do not want?
Tesco says that, when substitutions are allowed, you can hand an unwanted substitute back to the driver or Click+Collect colleague for a refund. Check a proposed custard substitute’s format, nutrition and allergen label before accepting it.
