Who is this for?

Fat-first label comparers

You want to compare the declared fat per 100g across single tins, rather than relying on front-of-pack wording.

Portion-conscious dessert eaters

You want a 400g tin to work for one or two people without overlooking the suggested serving size or the instructions for leftovers.

Milk-allergen label checkers

You need to check ingredients and allergen information before deciding whether a custard is suitable, regardless of its fat content.

What to check before buying

Concern What to check Who this matters to
Fat per 100g Compare the fat line on ready-to-serve tins using the same per-100g basis. ASDA Groceries lists 0.6g for Just Essentials, 1.6g for ASDA Light and 2.0g for Ambrosia Low Fat. If I am choosing mainly by fat content, I want a figure I can compare across tins with different serving suggestions. About 42% of consumers put declared fat per 100g first.
Portions and leftovers Check the suggested servings and opened-pack directions. Ambrosia states three 130g portions; the two ASDA tins suggest two servings. All three direct refrigerated use of leftovers within three days. A whole tin may be more than I intend to serve, and I need a plan for what remains. For about 33% of consumers, portion and leftover management is the primary concern.
Other label details Read sugars for the amount you will serve, and check the current ingredients and milk-allergen statement. ASDA Groceries lists sugars of 7.4g to 8.3g per 100g across these three tins. If milk is a concern for me, its presence needs checking before I eat the custard; I may also want to compare sugars separately from fat. About 25% of consumers put these other label checks first.

Common buying mistakes

  • Treating one tin as one portion

    The 400g tins have different suggested serving sizes, so figures given per portion may not describe the amount you plan to eat.

    Compare nutrition values per 100g, then use your intended serving size to assess the amount you will consume.

  • Looking only for low-fat wording

    ASDA Groceries lists 0.6g fat per 100g for Just Essentials by Custard, although ASDA Light is the tin explicitly labelled as a light option.

    Read the fat figure on each suitable tin, then consider sugars and serving size separately.

  • Leaving custard in an opened tin

    The listed products direct you to remove or transfer remaining custard from the can, refrigerate it and consume it within three days. Follow the directions on the tin you buy.

    Plan when you will use the remainder before opening a 400g tin.

    Custard left unused beyond the stated opened-pack period may be wasted.

  • Overlooking milk while comparing fat

    All three tins in this comparison contain milk; fat content does not establish allergen suitability.

    If milk is a concern, read the current ingredients and allergen statement before purchase or consumption.

Questions about tinned custard

Is a 400g tin one serving?

Not according to the serving suggestions for these tins. ASDA Groceries lists three 130g portions for Ambrosia Low Fat and two suggested servings for each ASDA tin; check the nutrition values against the amount you actually serve.

What should I do with custard left after opening?

Follow the directions on your tin. The Ambrosia and ASDA products discussed here direct you to remove or transfer the remainder from the can, refrigerate it and consume it within three days.

Does less fat also mean less sugar?

Not necessarily. ASDA Groceries lists 7.4g sugars per 100g for Ambrosia Low Fat, 8.3g for ASDA Light and 8.1g for ASDA Just Essentials by Custard, so compare the sugar and fat lines separately.

Can someone with a milk allergy choose one of these tins?

All three tins discussed here list milk-containing ingredients or identify milk as an allergen. Check the current ingredients and allergen statement for the exact product before considering it.
