Who this choice matters to
Shoppers planning portions
If it is easy to serve more than intended from an opened can, the declared portion and the amount in your own bowl both matter. The NHS notes that a manufacturer’s suggested portion may differ from yours.
Storecupboard shoppers
If you want custard ready to use from the cupboard, consider whether you can use the remainder within the pack’s refrigerated storage period after opening.

Common buying mistakes
-
Treating a light label as a serving plan
Ambrosia lists 101 kcal for a stated 130g portion of Light Devon Custard. Pouring more changes what the custard contributes to your dessert.
Decide how much you will serve, then use the pack’s per-100g figures to assess that amount.
-
Comparing portion figures without their weights
The cited Ambrosia cans define a portion as 130g, whereas Tesco Ready To Serve Custard uses 200g. Their per-portion figures therefore describe different amounts.
Compare products per 100g first, then check the figures for the serving you intend to eat.
-
Forgetting that storage changes after opening
The cited Ambrosia cans call for refrigeration and use within three days after opening; M&S gives two days for Silky Smooth Custard.
Follow the instructions on your pack and consider when the remaining custard will be used.
An unfinished pack may go to waste if you cannot use it within that period.
-
Assuming a familiar custard needs no ingredient check
The cited custards contain milk ingredients. A product name or a previous purchase is not a substitute for the current pack’s declaration.
If you need to avoid milk, read the ingredients and allergen information on the pack before buying or serving it.

Questions about tinned custard
Is light tinned custard always the right choice when managing weight?
No. A light recipe may suit you if you want to compare the custard’s listed calories, sugars and fat, but the amount served still matters. Ambrosia lists 101 kcal for a stated 130g portion of Light Devon Custard, compared with 125 kcal for the same stated weight of its standard Devon Custard.
Should I compare custards per portion or per 100g?
Start with per 100g to compare recipes on the same basis, then consider the amount you will serve. The cited Ambrosia cans declare a 130g portion, while Tesco Ready To Serve Custard declares 200g; the NHS also notes that a manufacturer’s portion may not match yours.
What should I do with custard left after opening?
Follow the instructions on the exact pack. Ambrosia instructs shoppers to remove remaining custard from its cited cans, refrigerate it and consume it within three days; M&S specifies refrigeration and use within two days for Silky Smooth Custard.
How can I check whether a custard contains milk?
Read the ingredients and allergen declaration on the current pack; the custards cited here contain milk ingredients. GOV.UK says prepacked foods containing any of the 14 regulated allergens must label them clearly.
