Who might choose each format

Hosts who need a tin

For a small Mexican-night dessert, the 400g Ambrosia Light can offers ready-to-serve custard and a stated sugar comparison with the brand’s standard custard. Check that its amount fits the dessert and number of guests.

Hosts serving several people

If a carton is acceptable, the 500g Ambrosia Light carton listed by ASDA Groceries provides four 125g portions. Its listing gives 9.3g sugars per portion, making the planned serving size easier to assess.

Home cooks seeking no added sugar

If you can make the custard just before serving, Tesco’s No Added Sugar Instant Custard Mix offers a powder route. It requires boiling water and contains sweetener and milk-derived ingredients.

What matters when choosing

For a Mexican-night dessert, settle whether you need a ready-to-serve tin, then compare sugar information and the amount you intend to serve.

Concern What to check Who this matters to
Sugar information Check what a reduced-sugar claim compares with, plus sugars per 100g and per planned serving. If comparing sweetness levels is my priority, I need the nutrition panel rather than the word “light” alone. About 50% of consumers put sugar comparison first.
Tin and quantity Confirm that the pack is a can, that it is ready to serve and that its weight fits the dessert. When I need custard straight from a tin for a small dessert course, a carton will not meet that preference. Roughly 30% of consumers prioritise the tin and ready-to-serve format.
Preparation and portions Check whether preparation needs boiling water, how portions are measured and whether the ingredients suit your guests. If making only the amount needed or serving separate portions matters more than having a tin, I can consider powder or pots. Around 20% of consumers put preparation or portion flexibility first.

Checks before you buy

  • Reading “reduced sugar” as “no added sugar”

    Ambrosia’s 30% less-sugar claim for its Light can compares it with Ambrosia Devon Custard; the Light can still contains sugar. Tesco’s no-added-sugar instant powder is a different product and format.

    Read the comparison on the can alongside its ingredients and nutrition panel. If no added sugar is your requirement, check that wording on the exact product you plan to use.

  • Picking a carton when the dessert plan calls for a tin

    The 400g Ambrosia Light can is ready to serve, while the 500g Ambrosia Light product listed by ASDA Groceries is a carton. The formats are not interchangeable if the container matters to your plans.

    Choose the format first, then check the pack weight against the portions you expect to serve.

  • Overlooking milk ingredients on a lighter custard

    The Ambrosia Light can and Tesco’s no-added-sugar instant mix contain milk-derived ingredients. GOV.UK states that required allergens must be emphasised in the ingredients list on UK pre-packed food labels.

    Before serving someone with a milk allergy, read the current pack’s ingredients and allergen declaration rather than relying on its front-of-pack description.

Brands to consider

Ambrosia

Ambrosia makes a 400g ready-to-serve Light Devon Custard can, as well as Light custard in other formats.

  • Ambrosia says the can has 30% less sugar and fat than its standard Devon Custard and can be served hot or cold.
  • The comparison does not mean no added sugar; the can contains sugar and milk ingredients.

Tesco

Tesco’s 70g No Added Sugar Instant Custard Mix is an alternative when a ready-to-serve tin is not essential.

  • The mix is labelled no added sugar and is prepared with boiling water.
  • It is a powder, not tinned custard, and contains sweetener and milk-derived ingredients.

Sainsbury’s

Sainsbury’s lists its own-label Ready To Eat Lighter Custard 500g and Instant Custard Powder No Added Sugar 72g.

  • These listings give shoppers ready-to-eat and make-at-home formats to consider.
  • Check the exact pack’s format, ingredients and nutrition before treating either as a reduced-sugar tinned option.

Bird’s

Bird’s ready-to-make and instant custard powders appear in Sainsbury’s custard range.

  • Powder is an option to consider if making custard is part of the dessert plan.
  • Check the exact Bird’s pack for its sugar information; a powder listing alone does not establish that it meets a reduced-sugar requirement.

Common questions

Does 30% less sugar mean the Ambrosia Light can has no sugar?

No. Ambrosia compares its Ready To Serve Light Devon Custard Can with standard Ambrosia Devon Custard, and the Light can still lists sugar among its ingredients.

Can I serve the Light can hot or cold after a Mexican-night meal?

Yes. Ambrosia says its Light can can be served hot or cold. Choose the serving temperature to suit your planned dessert, and check that a 400g can provides enough for your guests.

What should I check if a guest has a milk allergy?

Check the current pack’s ingredients and allergen declaration before serving. The Ambrosia Light can contains milk ingredients, and Tesco’s No Added Sugar Instant Custard Mix contains milk-derived ingredients. GOV.UK states that required allergens are emphasised in the ingredients list on UK pre-packed food labels.

Is no-added-sugar powder a substitute for ready-to-serve tinned custard?

Only if you can change the format and prepare the custard. Tesco’s No Added Sugar Instant Custard Mix requires boiling water and contains sweetener; it will not meet a requirement for custard ready to serve from a tin.
