Who is this for?

Parents comparing dessert labels

You want a ready-to-serve tin for a quick dessert or topping, but fat and sugar values matter to your choice.

Parents planning around an unpredictable routine

Serving custard hot or cold is useful, provided you can also use the opened pack within its storage period.

Parents shopping for different household members

You need to establish who will eat the custard before deciding whether its milk ingredients or sugar content affect the purchase.

What matters when choosing?

Start with the nutrition values, then consider how you will serve and store the tin and who will eat it.

Concern What to check Who this matters to
Fat and sugars Compare fat, saturates and sugars per 100g; then read the values for the portion you would serve. If I am choosing a lighter cupboard dessert, I want to compare the label with a similar standard custard without assuming “light” means sugar-free. About 42% of consumers put this nutrition comparison first.
Serving and leftovers Check the pack format, number of portions and instructions for storing it after opening. When a quick dessert has to fit around an interrupted routine, I need a pack I can serve easily and finish in time. Manageable serving and leftovers are the primary need for about 33% of consumers.
Household suitability Read the current milk-allergen information; if serving a young child, consider age-appropriate feeding guidance separately from the adult low-fat label. If I am buying for someone else in the household, I need to establish whether the ingredients suit that person. About 25% of consumers make household suitability their first concern.

Common buying mistakes

  • Assuming low fat also means low sugar

    Ambrosia lists 7.4g sugars per 100g and 9.6g per 130g portion for its Light 400g can, despite its 2.0g fat per 100g.

    Read fat, saturates, sugars and energy on the same per-100g basis, then check the labelled portion.

  • Opening a tin for one occasional serving

    Ambrosia labels its Light 400g can as three portions and instructs consumers to refrigerate the remaining custard and use it within three days of opening.

    Before choosing a multi-portion tin, consider whether you will use the rest within that period. A smaller ready-to-eat format may involve less leftover custard, though it would not be tinned.

    Custard left unused beyond the opened-pack period may be wasted.

  • Choosing one dessert for everyone without checking

    Ambrosia Light custard contains milk-derived ingredients. An adult low-fat label also does not establish suitability for a baby or young child; NHS guidance advises avoiding foods and drinks containing sugar or sweeteners for children aged four or under.

    Check the current allergen label and decide separately who the custard is for.

Brands to consider

Ambrosia

Ambrosia’s Ready To Serve Light Devon Custard is a 400g tin that the brand says can be served hot or cold.

  • Ambrosia lists 2.0g fat and 7.4g sugars per 100g for this Light tin, compared with 2.9g fat and 10.6g sugars for its standard 400g Devon Custard tin.
  • The Light custard contains milk; once opened, remaining custard must be refrigerated and used within three days.

Tesco

Tesco Groceries lists Tesco Reduced Fat Custard in 500g and 1kg formats for shoppers willing to consider a format other than a tin.

  • The two listed pack sizes offer different quantities to consider.
  • If a tin or a direct nutrition comparison matters, check the individual product’s packaging and per-100g label before choosing.

Questions about low-fat tinned custard

Does low-fat custard also contain less sugar?

Not necessarily: check sugars separately for each product. Ambrosia lists 7.4g sugars and 2.0g fat per 100g for its Light 400g tin, against 10.6g sugars and 2.9g fat for its standard 400g tin; that comparison applies to these two cans, not every reduced-fat custard.

How do I store an opened tin?

For Ambrosia Light 400g custard, remove any remaining contents from the tin, refrigerate them and use them within three days, according to Ambrosia’s product instructions.

Is this custard suitable for a baby or young child?

Do not treat an adult low-fat label as a guide to feeding a baby or young child. Ambrosia Light custard contains milk and sugars, while NHS guidance advises avoiding foods and drinks containing sugar or sweeteners for children aged four or under.

Can someone with a milk allergy have Ambrosia Light custard?

Ambrosia Light custard contains skimmed milk, buttermilk and whey, and its allergen information identifies milk. Check the current pack label when buying.

What does a “low fat” claim tell me?

GOV.UK says nutrition claims such as “low fat” must follow specific rules. The claim does not tell you the sugar content or your serving’s nutrition values, so compare those figures on the product labels too.
