Hosts comparing fat and saturates
If the dessert sauce needs a lower-fat profile, compare the figures per 100g across the packs you might serve. The NHS food-labelling guide defines low fat as 3g or less and low saturates as 1.5g or less per 100g.
Who this choice matters to
Hosts checking sugar and portions too
A reduced-fat label does not settle the sugar comparison. Ambrosia lists 7.4g sugars per 100g for Light Devon Custard, while Asda lists 12g per 100g for its 30% Less Fat Custard. The amount served to each guest also matters when planning the dessert.
Hosts planning around guests and leftovers
Check the milk allergen statement, the quantity needed for the table and the opened-pack instructions. Bird's custard powder allows a choice of milk and sugar during preparation, but its own allergen statement and every ingredient used still need checking for guests with dietary requirements.
What to check before buying
For a dinner party, compare ready-to-serve custards on a per-100g basis, then choose a pack and preparation method that suit the guest list.
| Concern | What to check | Who this matters to |
|---|---|---|
| Fat and saturates | Compare both figures per 100g on the exact ready-to-serve packs. Asda lists 1.4g fat and 0.7g saturates; Ambrosia Light lists 2.0g and 1.0g. | If keeping fat and saturates down is my deciding concern, I want to compare sauces on the same basis. About 46% of consumers would put fat and saturates first. |
| Sugar and portions | Read sugars and energy per 100g, then consider the amount you intend to serve. Ambrosia Light lists 7.4g sugars per 100g; Asda 30% Less Fat lists 12g. | When I am serving a smaller helping alongside pudding, I want the sugar figure and planned portion to inform my choice. Sugar and portion size would be the primary concern for about 27% of consumers. |
| Guests and service | Check the current pack's allergens and opened-storage instructions, then match its size to the number of servings needed. | If a guest cannot have milk, or I expect leftovers, suitability and serving plans must come before the nutrition comparison. Roughly 27% of consumers would make guest needs and service their first consideration. |
Mistakes to avoid
-
Reading “less fat” as “less of everything”
A percentage reduction compares a custard with a specified standard product; it does not establish how that custard compares with every other brand. Asda's reduced-fat custard and Ambrosia Light have different fat and sugar figures per 100g.
Compare fat, saturates, sugars and energy on the nutrition panels of the exact packs under consideration.
-
Choosing a large carton without planning for what remains
A larger pack may suit several guests, but opened custard has storage instructions. Ambrosia says to refrigerate its Light Devon Custard after opening and consume it within three days; Marks & Spencer specifies two days for its Silky Smooth Custard.
Estimate how much the dessert needs, and follow the opened-storage directions on the pack you buy.
-
Assuming “light” or “vegetarian” means milk-free
The researched Ambrosia, Asda and Tesco ready-to-serve custards contain milk. A fat claim or vegetarian label does not answer an allergen question.
Check the current physical pack's ingredients and allergen statement before serving anyone with a milk allergy or intolerance.
-
Treating custard powder as ready-to-serve
Bird's Original Custard Powder needs measured ingredients, heating and stirring. Its prepared nutrition figures are based on semi-skimmed milk, so they are not figures for every milk-and-sugar combination.
Choose powder when preparing custard to your chosen recipe fits the dinner-party plan; choose a ready-to-serve pack when preparation time is the deciding factor.
Powder also means allowing time for cooking and washing up.
Brands and product lines to compare
Ambrosia
Light Devon Custard is a ready-to-serve option offered as a 400g can and a 1kg carton.
- Ambrosia lists 2.0g fat, 1.0g saturates and 7.4g sugars per 100g for its 1kg Light carton, which it describes as approximately eight servings.
- It contains milk and needs refrigeration and use within three days of opening. Ambrosia's “30% less sugar and fat” claim compares it with Ambrosia Devon Custard, not every rival product.
Asda
The 500g 30% Less Fat Custard is a ready-to-serve own-label option to compare by its absolute nutrition figures.
- Asda lists 1.4g fat and 0.7g saturates per 100g.
- It also lists 12g sugars per 100g and contains milk; a lower fat figure does not answer a sugar or allergen requirement.
Tesco
Tesco Light Custard Ready To Serve is a 1kg carton for hosts considering a larger pack.
- Tesco lists 1.5g fat and 0.8g saturates per 100g.
- It lists 11.3g sugars per 100g and contains milk. Check local availability before including it in a dinner-party shopping plan.
M&S
Silky Smooth Custard is a whole-milk ready-to-serve alternative when a low-fat choice is not the priority.
- Its whole-milk formulation gives hosts a distinct option to consider for the dessert course.
- Marks & Spencer lists 3.7g fat and 2.6g saturates per 100g, above the NHS low-fat and low-saturates guides. It contains milk.
Bird's
Original Custard Powder is a make-to-order alternative, not tinned ready-to-serve custard.
- Bird's gives preparation instructions using several milk choices and allows the amount of added sugar to vary.
- It requires heating and stirring. Bird's does not confirm its Original Custard Powder as gluten-free, and its prepared nutrition figures use semi-skimmed milk.

Common questions
Does low-fat custard also have less sugar?
Not necessarily. Compare sugars as well as fat per 100g: Ambrosia lists 2.0g fat and 7.4g sugars for Light Devon Custard, while Asda lists 1.4g fat and 12g sugars for its 30% Less Fat Custard. The NHS food-labelling guide sets separate low-fat and low-sugars thresholds of 3g fat and 5g sugars or less per 100g, respectively.
How much custard should I plan for a dinner party?
Start with the pack's stated portions, then consider the dessert and how much sauce you intend to serve. Ambrosia describes its Light Devon Custard 1kg carton as approximately eight servings, so compare that with your guest count rather than assuming one pack will cover every serving style.
Can I heat ready-to-serve custard before guests arrive?
You can serve the researched Ambrosia and Asda ready-to-serve custards hot or cold, but follow the heating directions on the exact pack. Their instructions call for gentle heating and stirring; Asda also says not to reheat its product. Plan the timing around those directions rather than assuming custard can be repeatedly heated.
Is low-fat ready-to-serve custard suitable for a guest with a milk allergy?
Do not assume it is: the researched Ambrosia, Asda and Tesco ready-to-serve products contain milk. Check the current physical pack's ingredients and allergen statement before serving. If making Bird's custard powder with a different milk, check the powder and every ingredient used as well; changing the milk alone does not establish suitability.
