Who is this for?

Students prioritising lower fat

You want to compare fat figures per 100g rather than rely on words such as “lighter” or “reduced fat”. The ready-to-serve Asda, Sainsbury’s and Tesco products described by those retailers list 1.4–1.5g fat per 100g.

Students buying for a shared household

You can plan several desserts from a larger pack. The compared own-label options include 500g and 1kg formats; check how much your household will use after opening.

Single occupants avoiding waste

You want a ready-to-serve pack you can finish promptly. The compared Asda, Sainsbury’s, Tesco and Ambrosia products require refrigeration after opening and use within three days.

What matters when choosing?

Start with the per-100g nutrition panel, then consider how much custard you will use and where you will store the opened pack.

Concern What to check Who this matters to
Fat and sugars Compare both figures per 100g and read what any reduced-fat claim is compared with. If lower fat is my main reason for buying custard, I need the nutrition figures rather than the label wording alone. About 42% of consumers put the fat figure first.
Usable pack size Check the pack weight and how many portions you expect to use within three days of opening. When several people will share desserts, I want a pack that fits what we will actually use. Usable pack size comes first for about 33% of consumers.
Opened-pack storage Read the refrigeration instructions and check whether a can’s leftovers must be transferred to another container. Living alone, I need fridge space and a realistic plan for leftovers before opening a pack. Around 25% of consumers make avoiding opened-pack waste their primary concern.

Common buying mistakes

  • Treating “reduced fat” and “low fat” as interchangeable

    A reduced-fat statement compares a product with a reference product; it does not tell you its sugar content or how its fat figure compares with every other custard.

    Read the fat and sugars figures per 100g, along with the comparison named on the pack.

  • Choosing a large pack without planning portions

    A 1kg pack may be difficult for one person to finish when its instructions require refrigeration and use within three days of opening.

    Consider how many desserts you will make in that period before choosing between a 400g, 500g or 1kg pack.

    Unused custard may need to be discarded after the stated opened-pack period.

  • Leaving opened custard in the cupboard

    Being suitable for ambient storage before opening does not mean leftovers can be stored there.

    Make fridge space before opening the pack. Follow its instructions for transferring leftovers from a can, refrigerating them and using them within the stated period.

  • Confusing custard powder with a ready-to-serve can

    Bird’s Custard Powder requires preparation, and the finished custard depends on the ingredients used. Its Joybuy listing says to refrigerate prepared custard and treat it as fresh food.

    If you want custard you can serve without preparation during a move-in, check that the product is ready to serve.

    Powder also requires preparation time and ingredients.

Brands to consider

Ambrosia

Its Low Fat Custard is a ready-to-serve 400g can relevant to this tinned-custard choice.

  • The Joybuy listing gives 2.0g fat and 7.4g sugars per 100g.
  • It contains milk. After opening, the listing instructs you to transfer leftovers from the can, refrigerate them and use them within three days.

Asda

Its 30% Less Fat Custard is a ready-to-serve 500g option; the reduction refers to Asda’s standard equivalent.

  • ASDA Groceries lists 1.4g fat per 100g.
  • It also lists 12g sugars per 100g and contains milk.

Sainsbury’s

Its Ready To Eat Lighter Custard comes in a 500g pack; its lighter claim compares it with Sainsbury’s standard custard.

  • Sainsbury’s lists 1.5g fat and 11.8g sugars per 100g.
  • It contains milk, and leftovers must be refrigerated and used within three days.

Tesco

Its Reduced Fat Custard is a ready-to-serve option available in a 1kg format; its reduction claim compares it with Tesco Ready To Serve Custard.

  • Tesco Groceries lists 1.5g fat and 11.3g sugars per 100g.
  • The product contains milk, and an opened pack must be refrigerated and used within three days.

Bird’s

The Bird’s product considered here is custard powder, not a ready-to-serve low-fat can.

  • Powder offers a prepare-at-home format for shoppers who want to make custard.
  • Its finished nutrition depends on preparation. The Joybuy listing says it may contain milk and that prepared custard should be refrigerated and treated as fresh food.

M&S

The M&S Collection Madagascan Vanilla Luxury Custard considered here is chilled rather than an ambient, lower-fat tinned option.

  • Marks & Spencer provides per-100g nutrition and chilled-storage instructions for this product.
  • It lists 13.6g fat per 100g and contains milk and egg, so it does not meet the stated lower-fat tinned-custard need.

Questions about lower-fat custard

What does “low fat” mean on a UK food label?

The UK nutrition-claims annex published by legislation.gov.uk limits a “low fat” claim for solid foods to products containing no more than 3g fat per 100g. A “reduced fat” claim makes a comparison instead, so check the product’s per-100g figure and the basis of that comparison.

Is lower-fat custard automatically lower in sugar?

No. Tesco Groceries lists 11.3g sugars per 100g for Tesco Reduced Fat Custard, Sainsbury’s lists 11.8g for its Ready To Eat Lighter Custard, and ASDA Groceries lists 12g for its 30% Less Fat Custard. Compare sugars separately if they matter to your choice.

How should I store ready-to-serve custard after opening?

Follow the instructions on your pack. The compared Asda, Sainsbury’s, Tesco and Ambrosia products instruct you to refrigerate leftovers and use them within three days; the Ambrosia listing also says to remove remaining custard from the can before refrigerating it.

Are these custards suitable for someone with a milk allergy?

The compared Asda, Sainsbury’s, Tesco and Ambrosia ready-to-serve products declare milk, so they are not suitable for someone who needs to avoid it. Check the physical pack before use, as ingredients and allergen information can change.
