Who is this for?

Reduced-sugar tin shoppers

You want custard that is ready to serve from a tin, with a sugar-reduction claim you can check on the exact pack.

Format-flexible dessert makers

You would consider an instant mix or a carton if its ingredients, nutrition label and preparation method better fit your priorities.

Premium-dessert texture seekers

You are choosing an accompaniment for a dessert such as crumble or sticky toffee pudding, and need to decide whether a richer whole-milk option matters more than a reduced-sugar claim.

What matters when choosing?

Decide whether the ready-to-serve tin and its comparative sugar claim are essential before considering custards in other formats.

ConcernWhat to checkWho this matters to
Reduced sugar in a tin Check the exact can’s comparison claim and sugars per 100g. Ambrosia compares its Light Devon Custard with Ambrosia Devon Custard, not with every custard. I want to open a tin and serve dessert without making custard from powder, but I still need a stated sugar reduction. About 46% of consumers would put that combined requirement first.
No added sugar in another format Check preparation and ingredients: Tesco’s No Added Sugar Instant Custard Mix requires boiling water and contains sucralose. If I can prepare custard before serving, the no-added-sugar label matters more to me than buying a tin. Consumers who would prioritise that trade-off account for about 27%.
Texture or fat content Compare sugars per 100g rather than relying on a lighter or creamy description. Check the nutrition panel of the specific pack. For my dessert, I may favour a richer texture or a lower-fat product even if reduced sugar is not established. About 27% of consumers would make one of those other qualities their primary concern.

Buying pitfalls

  • Assuming ‘lighter’ means less sugar

    Sainsbury’s says its Ready To Eat Lighter Custard has 50% less fat than its standard custard, but lists 11.8g sugars per 100g. Asda lists 7.4g per 100g for the Ambrosia light can.

    Compare the sugars-per-100g lines and identify what each product’s comparative claim is measured against.

  • Expecting an instant mix to serve like a tin

    Tesco No Added Sugar Instant Custard Mix is a powder prepared with boiling water, rather than ready-to-serve custard.

    Decide whether opening and serving immediately matters more than choosing a no-added-sugar mix; also check whether its sweetener suits your preferences.

  • Overlooking milk ingredients

    The Ambrosia light can contains milk, while Tesco’s mix includes milk-derived ingredients. A reduced-sugar or no-added-sugar description does not describe allergen suitability.

    Read the ingredient and allergen information on the current pack, particularly when buying for someone with a milk allergy.

  • Storing leftovers in the opened can

    Ambrosia’s instructions say to remove remaining custard from the can, refrigerate it and consume it within three days.

    Plan for leftovers when opening the 400g can, and transfer them to a suitable covered container for refrigeration.

Brands and retailer ranges to consider

Ambrosia

Ambrosia Ready To Serve Light Devon Custard Can is a 400g ready-to-serve option. Ambrosia states that it has 30% less sugar and 30% less fat than Ambrosia Devon Custard.

  • The stated comparison identifies both the product and the custard used as its reference.
  • It is not sugar-free and contains milk; the comparison does not apply against all custards.

Tesco

Tesco No Added Sugar Instant Custard Mix is a 70g powder prepared with boiling water.

  • Its no-added-sugar description offers a different label priority for shoppers willing to prepare custard.
  • It is neither tinned nor ready to serve; it contains sucralose and milk-derived ingredients.

Sainsbury’s

Sainsbury’s Ready To Eat Lighter Custard is a 500g carton. Sainsbury’s compares its fat content with that of its standard custard.

  • The ready-to-eat carton offers a format to consider when a tin is not essential.
  • Its stated 50% reduction concerns fat, while its label lists 11.8g sugars per 100g.

Asda

Asda’s listing for Ambrosia Light Low Fat & Reduced Sugar Custard Dessert Can provides a retailer reference for the 400g format and its nutrition label.

  • The listing gives sugars as 7.4g per 100g and 9.6g per 130g portion.
  • The product contains milk and requires refrigeration after opening; check the current pack when buying.

M&S

M&S describes its Silky Smooth Custard as made with whole milk for a rich, creamy texture.

  • Its whole-milk positioning is relevant when dessert texture is the priority.
  • Check the current pack’s sugars figure and packaging format before treating it as a reduced-sugar tinned option.
