Buy ready-to-serve custard as a dessert, not as the part of a meal you rely on for protein: the Ambrosia and Tesco products considered here list 2.4g to 2.9g protein per 100g. If you want to stock up, compare the nutrition per 100g and choose a pack size your household can finish after opening. Ambrosia's 400g tins leave a smaller opened quantity than its 1kg carton; both formats must be refrigerated and used within three days of opening.
If custard is part of dessert, check how much protein your actual serving contributes rather than relying on its milk ingredients. Ambrosia and Tesco list 2.4g to 2.9g protein per 100g for the ready-to-serve examples considered here.
If you use custard regularly, compare the per-100g labels of standard and lighter recipes. Ambrosia lists lower sugars and fat for its Light 400g tin than for its standard 400g tin, but their listed protein figures are close.
A smaller tin may be easier to finish when servings are occasional. A larger carton makes more sense when the household expects to use it repeatedly within the stated period after opening.
Choose the format around how you will serve custard, then compare the nutrition label and the quantity you can use after opening.
Consider when: A smaller opened quantity suits occasional servings.
Trade-off: The cited Ambrosia tins still need refrigeration and use within three days once opened.
Consider when: Several people will share it or you expect repeated servings.
Trade-off: Ambrosia's carton lists eight portions, all to be used within three days of opening.
Consider when: Choosing the milk and added sugar matters more than immediate serving.
Trade-off: Bird's stated method requires preparation with milk and sugar; the finished nutrition depends on what you use.
| Concern | What to check | Who this matters to |
|---|---|---|
| Protein contribution | Protein per 100g and per planned serving; whether the figures describe ready-to-serve or prepared custard. | If custard accompanies a protein-focused meal, I need to know what my serving actually contributes. About 50% of consumers put protein contribution first. |
| Sugars and fat | Sugars and fat per 100g for the specific recipe, alongside its protein figure. | When choosing a lighter recipe for regular desserts, I want its sugars and fat to fit my preferences without mistaking it for a protein-focused product. For about 30% of consumers, this profile is the primary concern. |
| Pack size and leftovers | Net quantity and the pack's refrigeration and use instructions after opening. | If my household serves custard only occasionally, I would rather open a quantity we can finish than leave a larger pack unused. Avoiding leftovers comes first for about 20% of consumers. |
The Ambrosia and Tesco ready-to-serve products considered here list 2.4g to 2.9g protein per 100g. Milk in the ingredients does not tell you what a serving contributes.
Check protein per 100g and for the amount you plan to serve. If protein is the priority, plan that part of the meal separately.
Ambrosia says its cited 400g tins and 1kg carton must be refrigerated and consumed within three days of opening.
Choose the opened quantity around your household's likely use over those three days.
Custard left unfinished after that period can become food waste.
Ambrosia lists 2.9g protein per 100g for its Light 400g tin and 2.8g for its standard 400g tin. Its Light tin has lower listed sugars and fat, but the protein figures are close.
Compare all three figures on the current label rather than choosing by the recipe name alone.
The cited ready-to-serve products contain milk ingredients, and product information can change.
If milk allergy is relevant, read the ingredients and allergen declaration on the pack before buying or serving.
Ambrosia lists standard and Light 400g ready-to-serve tins, as well as a larger 1kg ready-to-serve carton.
Tesco Ready To Serve Custard is a 400g tin to compare with other single-tin options.
Bird's Original Custard Powder is a make-at-home alternative, not a tin of ready-to-serve custard.
These Ambrosia selections cover two 400g custard tins and a 1kg carton for households considering a larger ready-to-serve pack. The carton is not a tin or a confirmed multipack.

Consider this 400g ready-to-serve tin if you prefer a smaller opened pack and want to compare its sugars and fat with the standard Ambrosia recipe.
The product information lists 2.9g protein, 7.4g sugars and 2.0g fat per 100g. It contains milk; refrigerate after opening and consume within three days.

This standard ready-to-serve tin keeps the opened quantity smaller than a 1kg carton.
The product information lists 2.8g protein per 100g. It contains milk; refrigerate after opening and consume within three days.
Do not rely on the ready-to-serve examples here for a substantial protein contribution. Ambrosia lists 2.8g to 2.9g protein per 100g for its cited tins, while Tesco lists 2.4g per 100g; check the amount in the serving you intend to eat.
Choose the format your household can finish after opening. Ambrosia lists eight portions for its 1kg carton and says to refrigerate and consume it within three days of opening; its 400g tins leave a smaller quantity to use over the same period.
Read the current pack's ingredients and allergen declaration before buying or serving. The cited ready-to-serve custards contain milk ingredients; do not rely on an online listing in place of the pack.
Preparation changes which nutrition figures apply, but powder is not automatically a protein-focused choice. Bird's lists 3.1g protein per 100g when its Original Custard Powder is prepared with semi-skimmed milk; check the ingredients and quantities you actually use.
