What matters when choosing
For a secondary-school packed lunch, decide whether you can manage an opened pack at home before choosing between a larger format and sealed pots. Then check the serving format and the exact product label.
| Concern |
What to check |
Who this matters to |
| Leftovers |
Check the post-opening refrigeration instructions and whether the remainder can be used in time. |
If I open a larger pack for one lunch, I need a plan for the custard left at home. About 33% of consumers put managing those leftovers first. |
| Portion size |
Check the pack weight and stated serving size against the number of portions you intend to prepare. |
When I prepare several lunches, I want to know how many portions one pack provides before opening it. For about 25% of consumers, that is the main consideration. |
| Sealed packing |
Check that the portions are individually sealed and ready to eat cold, and follow their storage instructions. |
On a morning when I do not want to decant custard, a sealed pot is simpler to pack. Around 25% of consumers chiefly want that convenience. |
| Ingredients and allergens |
Read the current label for ingredients, highlighted allergens and precautionary statements; check the school’s policy too. |
If an ingredient could affect whether custard belongs in the lunchbox, I need to check the exact product rather than the category name. That is the primary concern for about 17% of consumers. |

Questions about custard for packed lunches
Is a 400g custard tin one lunch portion?
Not necessarily: Ambrosia labels its 400g Devon Custard can as three 130g portions. If using that tin for lunches, divide it at home and follow its instructions for storing the remainder.
How long can I keep custard after opening it?
Follow the exact pack’s instructions. Ambrosia and Tesco specify refrigeration and use within three days for their cited 400g products, while M&S says to refrigerate and eat its 400g Silky Smooth Custard within two days.
Does every tinned custard contain egg?
Do not assume that egg is present or absent across the whole category. Read the ingredients, highlighted allergens and any precautionary statement on the exact current pack. A plant-based description does not settle every allergy question: Ambrosia’s Plant Based Custard states “May contain Milk”.
Are individual custard pots easier to pack for school?
Individual pots avoid dividing an opened family pack. Sainsbury’s describes the Ambrosia 4 × 120g pots as ready to eat cold and suitable for lunchboxes, with no need to chill the unopened pots. Check the chosen product’s storage directions and the school’s packed-lunch policy.
Should I check the school’s policy before packing custard?
Yes. Check the school’s packed-lunch and allergy policy alongside the current product label, particularly where an ingredient or allergy affects whether the custard can be packed.
