Lunch planners using several portions
A 400g ready-to-serve tin may suit you if several people will share it, or if you can refrigerate the remainder and use it within the pack’s stated period.
Who is buying for an office lunch?
Solo desk-lunch eaters
If you want custard for one lunch and cannot store an opened tin, an ambient single-serve pot avoids taking home leftovers. Check its serving size against the amount you want.
Ingredient-conscious shoppers
If ingredients, allergens or nutrition values affect your choice, compare the exact variants rather than relying on their names. The Ambrosia standard and Low Fat custards considered here both list milk.
What matters when choosing?
For a packed lunch, decide how much custard you will use and what you can do with an opened pack before comparing variants.
| Concern | What to check | Who this matters to |
|---|---|---|
| Usable servings | Compare pack size and labelled portions with the amount you can use. | If I can share a tin across lunches, I want to use its contents rather than leave some behind. About 36% of consumers put usable servings first. |
| Leftover storage | Check the post-opening instructions and whether you have fridge access; consider an ambient single serving. | For one desk lunch without somewhere to keep an opened tin, I need a portion I can finish. Leftover handling is the main concern for about 29% of consumers. |
| Ingredients and nutrition | Read the current allergen and ingredient information and compare nutrition values per 100g. | When an ingredient or nutrition value affects my choice, I need to check the exact variant. Roughly 21% of consumers make that their primary concern. |
| Serving at work | Confirm whether the exact product is ready to serve cold and follow its heating directions if warming it. | Without dependable access to a microwave, I want custard I can eat cold. Serving flexibility comes first for about 14% of consumers. |
Packing mistakes to avoid
-
Packing a multi-portion tin without a leftover plan
Ambrosia Devon Custard 400g is labelled as three portions. Its product information says to remove the remaining custard from the can, refrigerate it and consume it within three days of opening.
Share the tin or arrange suitable storage for the remainder; if neither works, compare a single-serve ambient format.
Otherwise, an unfinished portion may go unused.

Assuming Low Fat means dairy-free
Ambrosia Low Fat Custard lists milk. Its name describes a fat-related difference, not the absence of a milk ingredient.
Check the current ingredients and highlighted allergens on the exact pack separately from its nutrition panel.

Common questions
Is a 400g tin practical for one office lunch?
Yes, if you can share it or store the remainder as directed. Ambrosia Devon Custard 400g is labelled as three 130g portions; its instructions say to refrigerate the remaining custard after opening and consume it within three days.
Can I eat ready-to-serve custard cold at work?
Ambrosia Devon Custard 400g can be eaten cold or warmed. Check the serving instructions on the exact product you pack rather than assuming every custard has the same directions.
When does a single-serve pot make more sense than a tin?
A single-serve pot is easier to manage when you want one portion and cannot refrigerate leftovers. Ocado describes the 150g Ambrosia Devon Custard Dessert Snack Pot as not needing chilling before opening; follow its pack directions once opened.
How do I check whether a custard contains milk?
Read the ingredients and highlighted allergens on the current pack. Both the Ambrosia standard and Low Fat custards considered here list milk; a Low Fat name does not mean a product is dairy-free.
