Who each format suits

Hosts who want a tin for a shared dessert

If you are buying custard for Christmas pudding, crumble or fruit and want a ready-to-serve tin, Ambrosia Light Devon Custard comes in a 400g can. Tesco Groceries lists three portions for that pack.

Planners serving several portions

If a carton works for your table, Tesco Reduced Fat Custard and Sainsbury's Ready To Eat Lighter Custard each come in a 500g pack listing four servings. Check the pack size against the portions you intend to serve.

Shoppers who prefer individual portions

Ambrosia lists its Light Devon Custard in 150g pots. Separate pots may fit a dessert plan where people are not being served from one shared pack; Ambrosia's comparison with its standard Devon Custard is a brand claim, not a comparison with every custard.

What to check before buying

For a Christmas dessert, decide whether the nutrition label, the serving format or allergen and leftover planning is your primary concern. Then compare the exact packs you are considering.

Concern What to check Who this matters to
Nutrition label Compare fat and sugars per 100g, as well as any other figures important to you, on the current pack. If fat is my priority, I still want to see how much sugar each custard lists before I choose. About 42% of consumers put the nutrition label first.
Pack and servings Check whether it is a tin, carton or pot, then check the net weight and stated servings. For a pudding shared at the table, I need enough custard without opening more than I expect to use. Pack format and portions come first for about 33% of consumers.
Allergens and leftovers Read the current milk-allergen information and the opened-pack storage instructions. When guests have food allergies, or custard may be left over, I need a pack I can serve and store appropriately. About 25% of consumers make these checks their primary concern.

Mistakes to avoid

  • Assuming every lower-fat custard is tinned

    The Ambrosia Light Devon Custard option is a 400g can, while the Tesco and Sainsbury's ready-to-serve options described here are 500g cartons. The distinction matters if you want a tin for your Christmas shop.

    Check the pack format and net weight, not just the lower-fat wording.

  • Reading “lighter” as “lower in sugar”

    Tesco Groceries lists 1.5g fat and 11.3g sugars per 100g for Tesco Reduced Fat Custard. Sainsbury's lists 1.5g fat and 11.8g sugars per 100g for its Lighter Custard. Tesco Groceries lists 2.0g fat and 7.4g sugars per 100g for the Ambrosia light can.

    Use the per-100g panel to compare the figures that matter to you rather than relying on the front-of-pack description.

  • Opening a shared pack without a leftovers plan

    The stated instructions for the Ambrosia light can and the Tesco and Sainsbury's cartons are to refrigerate after opening and consume within three days.

    Match the pack to the portions you expect to serve and follow its storage instructions once opened.

    An opened pack that cannot be used within its stated storage period may go to waste.

  • Serving custard without checking the allergen label

    Ambrosia Light and Tesco Reduced Fat list milk-derived ingredients. Sainsbury's says its Lighter Custard is not suitable for customers with a milk allergy because of its manufacturing methods.

    Read the physical pack's current ingredients and allergen information before serving anyone with an allergy, and keep the packaging available at the table.

Are the Tesco and Sainsbury's lighter custards tinned?
