Choose custard by the total carbohydrate in the amount you will actually eat, rather than treating a light or low-fat name as a suitability claim. An individual ready-to-eat pot gives you a fixed portion with a per-pot figure to check; a tin or prepared powder can also be portioned, but you need to measure what you serve. Check the current pack for ingredients and allergens as well as nutrition information.
If you use carbohydrate counting, the useful figure is total carbohydrate for the portion you eat. Diabetes UK advises checking total carbohydrate on the pack; a per-pot value is easier to use for a whole pot than a value that requires you to measure a serving from a larger pack.
A ready-to-eat pot sets a clear amount without serving from a tin or carton. Diabetes UK cautions that a portion printed on packaging is not necessarily the portion that suits every person, so check the pot size against your own plan.
If you are comparing custard recipes, look at total carbohydrate alongside labelled sugars and saturated fat on the same portion basis. A lighter recipe may have lower figures than its standard counterpart without being carbohydrate-free.
For a pot, check the value for the whole pot if that is what you will eat. For custard served from a larger pack or made from powder, use the nutrition information for the amount you prepare and serve.
| Concern | What to check | Who this matters to |
|---|---|---|
| Total carbohydrate | Read the total carbohydrate per pot or prepared serving; adjust the figure if you eat a different amount. | If I count carbohydrate, I need a figure for the custard I will actually eat, not just its sugars. About 36% of consumers put carbohydrate certainty first. |
| A predictable portion | Check the pot weight and whether its nutrition panel gives per-pot values; measure servings taken from a larger pack. | For a quick dessert, I may prefer a pot that sets the amount without measuring from a tin. About 29% of consumers primarily want that fixed-portion convenience. |
| Recipe differences | Compare total carbohydrate, sugars and saturated fat for equal portions, using the current pack. | When choosing between light and standard custard, I want to see what changes on the label without assuming either fits my plan. About 21% of consumers make recipe comparison their main concern. |
| Ingredients and preparation | Read the current allergen statement; for powder, check the preparation and storage instructions. | If I need to avoid an ingredient or prepare custard in advance, the ingredient list and instructions decide whether I can use it. About 14% of consumers put those checks first. |
These words do not tell you the total carbohydrate in your portion. Bird's lists 20.4g carbohydrate for a prepared 145g serving of its Low Fat Instant Custard.
Use total carbohydrate for the portion as your starting comparison, then look at sugars and saturated fat if those figures matter to your choice.
A per-100g comparison does not tell you how much carbohydrate you will have if the portions differ. Ambrosia also provides per-pot figures for its researched 150g pots.
Compare whole-pot values when eating a whole pot. Weigh a serving from a tin or prepared batch if you need to calculate from a per-100g figure.
If you serve custard with cake or pie, the custard label covers only the custard portion.
Account for the accompanying food separately when planning the whole dessert.
Ambrosia advises reading the physical pack because product formulations can change.
Check the nutrition and allergen information on the pack you are buying, particularly when a specific carbohydrate figure or ingredient matters to you.
Ambrosia lists ready-to-eat Devon Custard pots as well as larger formats, making its 150g Light and standard pots directly comparable by whole-pot nutrition.
Bird's instant custard is a prepare-at-home route for someone willing to measure a serving, rather than a sealed ready-to-eat pot.
Tesco Groceries lists ready-to-serve custard and no-added-sugar instant custard mix as different formats to compare.
These larger Ambrosia packs are for shoppers willing to portion custard themselves rather than buy a sealed individual pot. Check the amount you serve against the nutrition information on the current pack.

This 400g can is an option if you can measure a serving instead of relying on an individual pot. Check the current pack's carbohydrate value for the amount you eat, and follow its instructions for any custard left after opening.

This 1kg pack suits a household prepared to measure each serving. Check its own nutrition panel for the amount served; do not apply figures from the separate 150g Light pot. If a tin is essential, confirm this pack's format before buying.

This 400g can is for serving a measured amount rather than opening a single-portion pot. Weigh what you eat and use the current pack's total-carbohydrate information; “Low Fat” does not state the carbohydrate amount.
No. A fixed pot makes the amount clear, but its carbohydrate figure still needs to fit the person's own plan. Diabetes UK advises looking at total carbohydrate in the amount eaten rather than relying on a front-of-pack description.
Start with total carbohydrate for the portion you will eat. Diabetes UK explains that sugars form part of carbohydrate and advises checking the pack for total carbohydrate; the sugars figure can then help you compare recipes.
No. Ambrosia lists 18.2g total carbohydrate and 11.1g sugars for its Light Devon Custard 150g pot, compared with 22.2g carbohydrate and 15.9g sugars for its standard Devon Custard 150g pot. Those figures apply to the named pots, not to every pack size.
It can be an alternative if you are willing to prepare and measure each serving. Bird's says a sachet of its Low Fat Instant Custard makes three servings and lists 20.4g carbohydrate per prepared 145g serving; follow the pack's instructions for storing any custard you make.
Read the ingredient and allergen information on the current pack before choosing. The researched Ambrosia 150g pots and Bird's Low Fat Instant Custard list milk ingredients, so their light or low-fat names do not make them milk-free.
