Who each format suits

Shoppers who need a tin

A ready-to-serve can may suit a recipe that specifies tinned custard. Compare fat and sugars per 100g on the current label: the word “light” alone does not tell you both figures.

Students planning several portions

If a carton is acceptable, compare its pack size with the amount needed for dinner and any planned leftovers. A larger pack is useful only if you can store and finish the remainder as directed.

People willing to make custard

Bird’s Original Custard Powder is an alternative if you can prepare custard with milk, sugar and heat. Its prepared nutrition figures are based on semi-skimmed milk, so they should not be applied unchanged to a different recipe.

What to check before buying

Decide whether the tin itself matters, then compare nutrition per 100g and choose a pack you can use within its storage instructions.

Concern What to check Who this matters to
Fat and sugars Read fat, saturates and sugars per 100g on the current pack. Ambrosia Low Fat Custard 400g lists 2.0g fat and 7.4g sugars per 100g; ASDA Light Custard 400g lists 1.6g fat and 8.3g sugars per 100g. If the main aim is to choose a lower-fat dessert, I need the nutrition panel to support that choice without assuming it is also lower in sugars. About 40% of consumers put this nutrition comparison first.
Usable pack size Match the pack weight to the portions you need and decide whether a can is required; the checked cans are 400g, while the ready-to-serve alternatives discussed here include 500g packs. For dinner shared with others, I want enough custard without leaving more than I can use after opening. Roughly 40% of consumers make usable quantity their primary concern.
Preparation and storage Check whether the product is ready to serve or needs preparation, then read its allergen declaration and after-opening instructions. When time or kitchen equipment is limited, I want to know whether custard needs cooking and what to do with leftovers. About 20% of consumers place preparation and storage first.

Common buying mistakes

  • Assuming “lighter” tells you the whole nutrition story

    A reduced-fat comparison does not tell you how two different custards compare on fat or sugars. The Department of Health and Social Care states that a UK “low fat” claim on solid food requires no more than 3g fat per 100g.

    Compare the declared fat, saturates and sugars per 100g on the products you are considering.

  • Choosing a carton when the recipe calls for a tin

    Ready-to-serve cartons can provide custard for the same meal, but they do not meet a requirement for a canned product.

    Check whether “tinned” describes a necessary container or simply the convenient, ready-to-serve custard you had in mind.

  • Overlooking the opened-pack instructions

    The checked Ambrosia, ASDA and Sainsbury’s products call for refrigeration after opening and use within three days. Ambrosia also instructs users to transfer remaining custard out of the can.

    Choose a manageable pack size and follow the exact storage directions on the pack you buy.

    Custard left unused beyond the stated storage period may need to be discarded.

  • Assuming lower fat means suitable for a milk allergy

    The checked ready-to-serve custards declare milk, while Bird’s Original Custard Powder says it may contain milk. Fat content does not establish allergen suitability.

    If buying for someone with a milk allergy, read the ingredient and allergen declaration on the exact current product.

Brands to consider

Ambrosia

Its Low Fat Custard 400g is a ready-to-serve canned option for a tin-first choice.

  • The 400g Low Fat can lists 2.0g fat, 7.4g sugars and 78 kcal per 100g.
  • It contains milk; follow the can’s instructions for transferring and refrigerating leftovers.

ASDA

Its Light Custard 400g is a can; its separate 30% Less Fat Custard 500g is a ready-to-serve alternative when a tin is not essential.

  • ASDA lists 1.6g fat per 100g for the Light can and 1.4g per 100g for the 500g product.
  • Both checked products contain milk. Confirm the container type when a recipe specifically calls for a tin.

Sainsbury’s

Ready To Eat Lighter Custard 500g is an option when a ready-to-serve carton will do.

  • The checked product lists 1.5g fat and 11.8g sugars per 100g.
  • It contains milk and calls for refrigeration and use within three days after opening.

Tesco

Tesco lists Reduced Fat Custard in 500g and 1kg sizes among its lower-fat custard options.

  • The two listed sizes offer a pack-size choice for different numbers of portions.
  • Use the current product label to compare its nutrition and confirm its container type.

Bird’s

Original Custard Powder is a make-your-own alternative, not ready-to-serve tinned custard.

  • Bird’s provides preparation directions using milk and sugar; its stated prepared figure is 1.5g fat per 100g when made with semi-skimmed milk.
  • Preparation needs heating, and the powder may contain milk.

M&S

Silky Smooth Custard is a canned reference for shoppers comparing standard custard with lower-fat choices.

  • Its label lists 3.7g fat per 100g, providing a clear figure for comparison.
  • At 3.7g fat per 100g, it is above the UK 3g-per-100g condition for a “low fat” claim on solid food stated by the Department of Health and Social Care.

Questions about low-fat custard

Does “low fat” mean custard is low in sugars?

No: compare sugars separately on the nutrition panel. The checked Ambrosia Low Fat 400g can lists 7.4g sugars per 100g, while ASDA Light Custard 400g lists 8.3g per 100g.

Can I use a carton instead of tinned custard?

Yes, if the meal does not require a can. Check that the carton is ready to serve, that its size suits the portions needed and that you can follow its instructions for any leftovers.

How should I store custard after opening it?

Follow the instructions on the exact pack. The checked Ambrosia, ASDA and Sainsbury’s products call for refrigeration and use within three days; Ambrosia also instructs users to transfer custard remaining in the can before refrigerating it.

Is the checked lower-fat custard suitable for a milk allergy?

Do not assume so: the checked Ambrosia, ASDA and Sainsbury’s ready-to-serve products declare milk, and Bird’s Original Custard Powder says it may contain milk. Read the current allergen declaration for the exact product you intend to use.
