Choose by the number of portions you expect to serve, rather than by the words “family pack”. Ambrosia labels its standard 1kg ready-to-serve carton as eight portions and its standard 400g can as three; a larger carton suits a group sharing one recipe, while smaller cans make it easier to open different recipes or only the quantity needed. Check the exact pack for milk ingredients and instructions for opened custard before deciding.
If everyone will have the same custard, portion guidance can help you decide whether one larger pack is enough. Ambrosia labels its standard 1kg carton as eight portions; plan for refrigeration if you expect to keep any after opening.
Smaller cans let you open one recipe without opening a larger pack, or serve separate varieties. Ambrosia labels its standard and light 400g cans as three portions each, so check the guidance on the particular cans you choose.
If you are choosing between standard, light and cream-containing custards, compare nutrition per 100g and the current ingredient and allergen statements. The Ambrosia, Tesco and M&S ready-to-serve products described here list milk-derived ingredients.
Start with the portions you need, then consider how much you will open at once and which recipe the group wants.
| Concern | What to check | Who this matters to |
|---|---|---|
| Enough portions | Check the stated serving count and portion size. Ambrosia specifies eight 125g portions for its standard 1kg carton and three 130g portions for its standard 400g can. | If I am sharing one dessert with a larger picnic group, I need to know whether a single pack will serve everyone. About 42% of consumers put having enough portions first. |
| Manageable leftovers | Decide how much to open at once, then follow that pack's instructions for storing and using any remainder. | For a smaller group, I would rather open only the custard we expect to use than leave much of a large pack unfinished. Keeping leftovers manageable is the primary concern for about 33% of consumers. |
| Recipe and ingredients | Compare nutrition per 100g and the current ingredient and allergen statements; check what product a light-recipe claim is compared with. | When guests want different recipes or need ingredient information, I want to check the precise custard before serving it. About 25% of consumers place recipe and ingredient choice first. |
Ambrosia describes its light 400g can as having 30% less sugar and fat than its standard Devon Custard; that comparison does not extend to other brands. M&S lists whole milk and cream in its 400g Silky Smooth Custard. A light recipe should not be taken to mean dairy-free: check the current label for anyone who needs to avoid milk.
Ambrosia's standard eight-portion, 1kg ready-to-serve pack is a carton. Its standard 400g tin is labelled as three portions, so a group committed to cans may need more than one.
Decide whether tin packaging matters before choosing a size, and use each pack's stated portions to work out how many to bring.
Opened-pack instructions differ. The Ambrosia and Tesco products described here specify refrigeration and use within three days, while M&S specifies two days for its 400g Silky Smooth Custard.
Read the instructions on the pack you take and plan how you will refrigerate any custard left after the picnic.
Opening more than the group needs can leave custard to discard if it cannot be used within the stated period.
Ambrosia's light custard lists milk-derived ingredients. Its sugar-and-fat comparison says nothing about whether the recipe contains milk.
If milk ingredients matter for someone you are serving, check the current ingredient and allergen statement on the exact pack.
These examples show different ready-to-serve formats and recipes; the brand name alone does not establish a pack's portions or opened-storage instructions.

Tesco lists own-label ready-to-serve custard in a 400g can and a 1kg carton.

This 400g tin offers a smaller-quantity, low-fat-recipe option. Check its own portion guide before deciding how many tins to take; do not assume it has the same serving count as another 400g variety.

Choose this 400g tin if you want a separate strawberry-flavoured custard alongside another recipe. Check the tin's portion guidance when planning quantities and follow its instructions for any opened remainder.
Start with the serving guide on the exact pack. Ambrosia labels its standard 1kg carton as eight 125g portions and its standard 400g can as three 130g portions; decide how many of those portions your group expects to use, particularly if custard is the main dessert rather than a topping.
Yes, the checked standard and light Ambrosia custards and Tesco ready-to-serve custard state that they can be served hot or cold. Follow the chosen pack's storage instructions, including its directions for any custard left after opening.
Use the instructions on the exact pack, rather than a single rule for all custards. The checked Ambrosia standard and light products and Tesco 400g can specify refrigeration and use within three days; M&S specifies two days for its 400g Silky Smooth Custard.
The checked Ambrosia, Tesco and M&S ready-to-serve products list milk-derived ingredients, so do not treat them as milk-free. Check the current ingredient and allergen statement on the exact pack before serving it to someone who must avoid milk.
