Who is choosing?

Shoppers set on a low-fat tin

You want custard that is ready to serve from a can. The fat figure per 100 g matters more to your choice than “light” wording on its own.

People planning a shared dessert

You are serving custard after a fish and chips meal and want to match the pack’s portions to the people eating, without opening more than you expect to use.

Shoppers checking ingredients and sugars

You need to check milk ingredients or want to compare sugars separately from fat. The nutrition and ingredient panels both matter before you choose.

What matters when buying?

Start with the fat figure and pack format, then choose a quantity that suits dessert and check the label for ingredients and storage instructions.

Concern What to check Who this matters to
A low-fat, ready-to-serve tin Check fat per 100 g and confirm that the pack is a can. Legislation.gov.uk states that a low-fat claim for solid food requires no more than 3 g of fat per 100 g; Ambrosia lists 2.0 g per 100 g for its 400 g Low Fat Custard can. If I specifically want custard from a tin, I need the fat figure to support the low-fat wording. About 50% of consumers put that combination first.
Portions for dessert Compare the declared portions and pack type. Ambrosia declares three 130 g portions for its 400 g can and eight 125 g portions for its 1 kg light carton. When several people are having dessert, I want a pack that fits how many will eat it and how much might remain. For about 30% of consumers, serving size and format come first.
Sugars, milk and leftovers Read the sugars and allergen information, then the after-opening instructions. Ambrosia lists 7.4 g sugars per 100 g for the low-fat can; Tesco says to remove leftovers from the can, refrigerate them and use them within three days. If milk ingredients or opened-pack storage affect what I can serve, those details take priority over the word “light”. They are the primary concern for about 20% of consumers.

What is easy to overlook?

  • Assuming “light” also means low in sugar

    Ambrosia lists 2.0 g fat and 7.4 g sugars per 100 g for its Low Fat Custard can. The fat claim does not tell you the sugar figure.

    Compare the nutrients you care about on the same pack’s per-100 g panel, alongside its portion information.

  • Choosing a carton or pot when you need a tin

    Ambrosia also sells light custard in other formats, but they do not meet a firm tinned-custard requirement. Their portions and handling instructions need checking separately.

    Decide whether the can is essential before comparing pack sizes.

  • Heating or keeping custard in the opened can

    Ambrosia’s heating instructions call for a microwaveable container. Tesco’s instructions for the Low Fat Custard can say to remove any remaining custard from the can before refrigerating it.

    Use the pack’s heating directions and transfer leftovers to a suitable covered container; refrigerate and consume them within the stated three days.

  • Overlooking milk ingredients

    Ambrosia’s Low Fat Custard can contains skimmed milk, buttermilk and whey. Lower fat does not remove those ingredients.

    Read the current pack’s ingredient and allergen information before serving someone who needs to avoid milk.

Brands and ranges to compare

Ambrosia

Its 400 g Low Fat Custard can fits the ready-to-serve tin format; Ambrosia also offers light custard in cartons and pots.

  • Ambrosia lists 2.0 g fat per 100 g and three portions for the can, which can be served hot or cold.
  • The can contains milk ingredients and 7.4 g sugars per 100 g; the cartons and pots are different pack formats.

Tesco

Tesco lists the Ambrosia Low Fat Custard can alongside its own ready-to-serve custard.

  • Its Ambrosia listing includes nutrition, ingredients and instructions for storage after opening.
  • Check the current fat figure and pack format before treating Tesco’s own custard as a low-fat tinned alternative.

Sainsbury's

Sainsbury's lists both the Ambrosia 400 g Low Fat Custard can and its own 500 g Lighter Custard.

  • The listings give you different named products and pack sizes to compare.
  • For the Sainsbury's lighter product, check the current nutrition panel and packaging before deciding whether it meets your fat and tin-format requirements.

Bird's

Bird's custard powders offer a make-it-yourself route rather than ready-to-serve custard in a tin.

  • Sainsbury's lists Bird's Original Custard Powder and Instant Custard sachets.
  • Powder needs preparation; check the finished custard’s ingredients and nutrition if you are considering it instead of a low-fat can.

M&S

M&S Madagascan Vanilla Luxury Custard is a chilled alternative, not a low-fat tinned choice.

  • M&S provides a per-100 g nutrition figure that makes the format and fat-content difference clear.
  • M&S lists 13.6 g fat per 100 g for this product, which also contains milk, cream and egg yolk.

Questions about low-fat tinned custard

What does “low fat” mean when choosing tinned custard?

For solid food bearing a low-fat claim, legislation.gov.uk sets a condition of no more than 3 g fat per 100 g. Ambrosia lists 2.0 g per 100 g for its 400 g Low Fat Custard can; check the figure on any other product rather than relying on similar wording.

Is Ambrosia’s low-fat custard also low in sugar?

A low-fat claim does not establish a low-sugar claim. Ambrosia lists 7.4 g sugars per 100 g for its 400 g Low Fat Custard can, so read the sugar figure separately if it matters to your choice.

How much dessert does the 400 g Ambrosia can provide?

Ambrosia declares three 130 g portions for its Low Fat Custard can. Use that serving guidance to plan how much custard to put out after the meal.

What should I do with custard left in an opened can?

For Ambrosia’s 400 g Low Fat Custard can, Tesco says to remove the remaining custard from the can, refrigerate it and consume it within three days. Follow the specific instructions on another product’s pack if you choose a different custard.
