Check the current pack’s allergy information before choosing a low-fat tinned custard. Ambrosia Light and ASDA Light both declare milk, so neither is suitable for someone avoiding milk because of an allergy. If milk is not the allergen to avoid, compare fat and sugars per 100g, portion sizes and instructions for storing leftovers; a lower-fat claim does not establish allergy suitability.
If you are buying for someone who must avoid a particular allergen, check the current ingredients and any precautionary statement before considering nutrition. Ambrosia Light and ASDA Light both declare milk, so neither is an option for milk-allergy avoidance.
If milk is not an allergen you need to avoid, you can compare ready-to-serve cans on the same per-100g basis. ASDA lists 1.6g fat per 100g for its Light Custard; Ambrosia lists 2.0g for its Light Devon Custard.
A 400g can may provide more than one serving. Consider how much you intend to use at once and whether you can refrigerate and use the remainder within the time stated on the pack.
Start with the exact pack’s allergen information. Compare nutrition and serving plans only for products that meet the person’s avoidance requirements.
| Concern | What to check | Who this matters to |
|---|---|---|
| Allergen suitability | Read the current ingredients, highlighted allergens and any “may contain” statement against the person’s avoidance requirements. | When buying for someone with a food allergy, I need to rule out an unsuitable ingredient or cross-contact warning before considering fat content. About 50% of consumers put allergen suitability first. |
| Nutrition and portions | Compare fat, saturates and sugars per 100g, then look at the intended serving size. | Once a custard meets my allergen requirements, I want to compare its fat figure without overlooking sugars or how much I will serve. For about 30% of consumers, that nutrition comparison is the primary concern. |
| Using the whole can | Check the serving guidance and the pack’s instructions for refrigerating and using leftovers. | If I will not use a whole can at once, I need a plan for the remaining custard. Using the opened pack is the main concern for about 20% of consumers. |
A fat claim describes nutrition, not allergen exclusion. The Ambrosia Light and ASDA Light cans both contain milk.
Check the exact pack against the relevant allergy requirements before comparing its nutrition panel.
