Households avoiding leftovers
For an occasional dessert in a one- or two-person household, a sealed individual pot avoids opening a 400g tin for one serving. Tesco Groceries and Sainsbury's list Ambrosia pots in 120g and 150g formats.
Who each format suits
Cupboard-stock dessert shoppers
A ready-to-serve tin suits households that can use it across several desserts. Once opened, follow that product's storage instructions rather than assuming the unopened pack's date still governs the remainder.
Shoppers comparing fat content
If fat content is your main consideration, compare the nutrition panels of the exact standard and lower-fat variants. Choose the pack format separately: a lower-fat 400g tin is still a multi-serve pack.
What matters when choosing
Start with how much custard you will serve at once, then compare the exact packs for nutrition and opened-pack storage instructions.
| Concern | What to check | Who this matters to |
|---|---|---|
| Leftovers | Check the pack size and whether each serving is separately sealed. For a tin, read its opened-pack storage instructions. | If custard is an occasional dessert, opening one pot avoids having to store the rest of a tin; about 50% of consumers put avoiding leftovers first. |
| Fat content | Compare the exact variants' nutrition information per 100g, alongside their ingredients and allergen statements. | When choosing between standard and lower-fat custard, I would check the fat figure before settling on a format; about 30% of consumers primarily want that comparison. |
| Dessert preference | Check the recipe description and declared serving size of a cream-enriched or deluxe variant. | For an occasional shared dessert, a cream-enriched recipe may be the deciding feature; about 20% of consumers put that preference first. |
Mistakes to avoid
-
Assuming a 400g tin is one portion
Individual pots listed by Tesco Groceries and Sainsbury's come in 120g and 150g formats, while Sainsbury's describes a 400g Ambrosia Deluxe tin as three 130g portions.
If you want one dessert at a time, consider a pot. Choose a tin when you can serve or store the remainder according to its label.
Custard left unused beyond the pack's stated opened-storage period may need to be discarded.
-
Treating lower fat as a complete dietary answer
A lower-fat designation does not tell you the pack's serving size, other nutrition values, ingredients or allergens.
Read the current label for the exact variant and compare its per-100g nutrition information with the alternative you are considering.
-
Applying one storage period to every tin
Opened-pack instructions vary: Marks & Spencer says to refrigerate its Silky Smooth Custard and eat it within two days, while Ambrosia says to refrigerate the remaining contents of its Strawberry Flavour Devon Custard 400g and consume them within three days.
Follow the instructions on the product you open, including any direction to remove leftovers from the can.
Brands and ranges to consider
Ambrosia
Tesco Groceries and Sainsbury's list Ambrosia ready-to-serve custard in 400g cans and individual pot formats.
- The listed formats include 120g multipack pots and 150g snack pots for individual servings.
- A 400g can is not individually sealed; check the exact variant's nutrition panel and opened-pack instructions.
Tesco
Tesco Groceries lists its own ready-to-serve custard as a 400g tinned option.
- The format can be divided between desserts when the household will use the contents.
- It does not provide separately sealed individual portions.
Sainsbury's
Sainsbury's lists own-label custard alongside Ambrosia tins and individual pots in its custard range.
- The listed range lets shoppers compare multi-serve and portioned formats.
- Check the pack format of the specific item rather than assuming every custard in the range is individually portioned.
M&S
M&S Silky Smooth Custard is a 400g can, not a single-serve pot.
- Marks & Spencer gives product-specific opened-pack guidance: refrigerate and eat within two days.
- That period matters if you expect to serve the can over more than one occasion.
Bird's
Bird's custard powder is a preparation option rather than ready-to-eat tinned custard.
- It is worth considering if making the quantity you need matters more than serving custard straight from a pack.
- It requires preparation, so it does not offer the same immediate serving format as a tin or pot.

Common questions
Is a tin of custard an individual portion?
Do not assume so. Tesco Groceries lists 400g products in its tinned-custard category, while its broader custard range includes individual pots; Sainsbury's states that an Ambrosia Deluxe 400g can contains three 130g portions. Check the serving information on the tin you choose.
How should I store custard left in an opened tin?
Follow that tin's instructions. Food Standards Scotland advises checking the label for refrigeration requirements after opening. Marks & Spencer specifies refrigeration and consumption within two days for its Silky Smooth Custard; Ambrosia gives a three-day period for its Strawberry Flavour Devon Custard 400g after removing the remainder from the can and refrigerating it.
Does a best-before date mean the same thing as a use-by date?
No. GOV.UK and the Food Standards Agency distinguish use-by dates, which concern safety, from best-before dates, which concern quality. Check the date marking as well as any separate instructions for storing custard after opening.
Must ready-to-serve tinned custard be heated?
Not necessarily. Sainsbury's Ambrosia Deluxe product information says that variant can be served hot or cold. Follow the heating directions on the exact product if you prefer it warm.
