Hosts prioritising lower fat
If a ready-to-serve tin and a lower fat figure are your priorities, compare the declarations per 100g rather than relying on words such as “light”. Check sugars separately: the figures are not interchangeable.
Who is choosing custard?
Hosts serving a small group
A 400g can may be easier to match to a modest serving plan than a 1kg carton. If you open more than you use, follow that pack's refrigeration and use-by-after-opening instructions.
Organisers checking allergens
Check the label of each custard you serve if a guest needs to avoid milk. The Ambrosia, ASDA and Tesco lower-fat products discussed here list milk or milk ingredients; a lower-fat description does not change that.
What matters when choosing?
Decide whether the container must be a tin before comparing pack sizes. For the remaining choices, use the same per-100g basis for nutrition figures and plan for any custard left after serving.
| Concern | What to check | Who this matters to |
|---|---|---|
| Fat in a tin | Compare fat per 100g on ready-to-serve cans; read sugars separately. Sainsbury's and Joybuy give different figures for the named Ambrosia 400g product. | If keeping fat lower is my main priority, I need a comparable figure from the can I will serve. About 40% of consumers put that need first. |
| Quantity and format | Match 400g cans or a larger carton to the expected servings, and confirm whether a tin is required. | For a larger gathering, I need enough custard without choosing a container that conflicts with my serving plan. Around 30% of consumers primarily weigh quantity and format. |
| Serving and leftovers | Check hot-or-cold serving directions and the opened-pack refrigeration period. | When attendance is uncertain, I want to open only what I can serve or store as directed. About 20% of consumers put convenient serving and avoiding leftovers first. |
| Milk and label details | Read the received pack's ingredients and allergen statement before serving. | If a guest must avoid milk, I need to establish what each served product contains before choosing by fat or size. Roughly 10% of consumers make that label check their primary concern. |
Mistakes to avoid
-
Reading “low fat” as the whole nutrition picture
Fat and sugars have separate declarations. The Tesco, ASDA and Sainsbury's listings for the lower-fat cans give different sugar figures per 100g.
Compare the figures that matter to your serving plan on the same per-100g basis, using the current pack as your final check.
-
Counting a carton as a tin
A ready-to-serve carton can cover a larger gathering, but it will not meet a specific preference for canned custard.
Settle the format question before comparing a 400g can with a 1kg carton.
-
Making the allergy check from an online listing alone
The lower-fat Ambrosia, ASDA and Tesco products discussed here contain milk or list milk ingredients. Product information can change.
Read the ingredients and allergen statement on the pack received, and check any separately served alternative in the same way.
-
Opening every can before guests arrive
Leftover custard must be stored according to its pack instructions. The researched lower-fat cans specify refrigeration and consumption within three days after opening.
If numbers are uncertain, open additional cans as needed rather than all at once.
Opening more than you can use within the stated storage period may leave custard to discard.
Brands to consider
Ambrosia
Its Low Fat Custard comes in a ready-to-serve 400g can.
- Sainsbury's lists 1.8g fat per 100g for the can and describes it as suitable hot or cold.
- Joybuy lists 2.0g fat per 100g for the same named 400g product. Check the nutrition panel on the can received.
Tesco
Tesco lists reduced-fat ready-to-serve custard in a 400g can and a 1kg carton.
- Its listings give 1.7g fat per 100g for the can and 1.5g per 100g for the carton.
- The 1kg option is a carton, so choose it only if the tinned format is flexible.
Asda
ASDA lists Light Custard in a 400g can.
- ASDA's listing gives 1.6g fat and 8.3g sugars per 100g.
- It contains milk; check the pack before serving anyone who needs to avoid it.
Sainsbury's
Its relevant listing is for Ambrosia Low Fat Custard Can 400g, rather than a separate Sainsbury's own-label product.
- The listing gives per-100g fat and sugars figures and describes hot-or-cold serving.
- Those nutrition figures differ from Joybuy's listing for the same named Ambrosia product; use the received pack for the final comparison.
M&S
M&S Silky Smooth Custard is a 400g canned option made with whole milk and cream.
- It provides a tinned format if lower fat is not the main requirement.
- Marks & Spencer lists 3.7g fat per 100g, above the figures listed for the lower-fat cans discussed here.
Bird's
Bird's Original Custard Powder appears in Tesco's custard assortment.
- Powder is an option if preparing custard is part of the serving plan.
- It requires preparation and should not be compared as a ready-to-serve can.
Joybuy custard selections
For a coffee morning, these Ambrosia selections cover a 400g low-fat custard can and a larger 1kg light custard carton. Choose the carton only if a tin is not essential.

Ambrosia Low Fat Custard 400g
Consider this 400g can when you want ready-to-serve custard for a smaller gathering. Joybuy lists 2.0g fat per 100g and declares milk; Sainsbury's lists a different fat figure for the same named product, so check the received can before making a nutrition comparison.

Ambrosia Light Devon Custard 1kg
Consider the 1kg carton if you expect to serve more guests and do not require a tin. Check how much you are likely to use and follow the pack's directions for any custard left after opening.
Common questions
Does low-fat tinned custard also have less sugar?
A lower-fat description does not tell you the sugar content. Tesco lists 7.4g sugars per 100g for its Reduced Fat Custard can, ASDA lists 8.3g for its Light Custard can, and Sainsbury's lists 11.1g for Ambrosia Low Fat Custard; check the pack you receive before comparing them.
Can I serve these canned custards hot?
The Ambrosia, ASDA and Tesco lower-fat cans discussed here are described as suitable for hot or cold serving. For hot custard, transfer it to suitable cookware and follow the heating instructions on its pack.
How should I store custard left after the coffee morning?
The Ambrosia, ASDA and Tesco lower-fat cans discussed here specify refrigeration and consumption within three days after opening. Check the particular pack: Marks & Spencer gives a two-day period for its separate Silky Smooth Custard product.
Are these lower-fat custards suitable for a guest with a milk allergy?
The Ambrosia, ASDA and Tesco lower-fat custards discussed here contain milk or list milk ingredients, so do not treat their lower-fat descriptions as evidence that they are suitable for someone who must avoid milk. Read the allergen statement on every pack you intend to serve.
