Choose a reduced-sugar tin if your recipe needs prepared custard without a mixing step: ASDA Groceries lists the 400g Ambrosia Light Low Fat & Reduced Sugar can with 7.4g sugars per 100g. If you can make the custard separately and want a product labelled no added sugar, Tesco No Added Sugar Instant Custard Mix is a powder alternative, but it requires boiling water and contains sucralose. Check the exact pack and your recipe’s required texture before swapping formats.
If you need prepared custard for a dessert or a recipe that calls for it, a reduced-sugar tin keeps the format you want. Tesco Real Food also features desserts made with tinned custard; check the instructions for your particular bake before using it as a filling or layer.
If you can prepare custard from a mix, Tesco’s no-added-sugar instant powder offers a different format. Check its sweetener, milk-derived ingredients and boiling-water instructions against your recipe and ingredient requirements.
If your recipe specifically asks for custard powder, Bird’s Original Custard Powder is a traditional dry ingredient rather than prepared custard. Its listed ingredients do not include sugar, but the ingredients added during preparation determine the finished dish.
Start with the format your recipe calls for, then compare the exact pack’s sugar information, ingredients and preparation instructions.
| Concern | What to check | Who this matters to |
|---|---|---|
| Reduced-sugar tin | Confirm it is prepared custard in a tin and compare sugars per 100g with the amount your recipe uses. ASDA Groceries lists 7.4g sugars per 100g for the 400g Ambrosia reduced-sugar can. | When a dessert needs custard ready to pour or heat, avoiding a mixing step is the primary concern. About 42% of consumers put that reduced-sugar tin format first. |
| No-added-sugar mix | Read the sweetener ingredients and preparation directions; Tesco’s instant mix contains sucralose and needs boiling water. | If a powder is workable, the no-added-sugar label may matter more than having a prepared tin. Around 33% of consumers prioritise that formulation. |
| Recipe-compatible powder | Check whether the recipe specifies dry custard powder or prepared custard, and review the ingredients added during preparation. | For a recipe written around custard powder, using the specified ingredient comes before tin convenience. Roughly 25% of consumers make recipe compatibility their primary concern. |
The 400g Ambrosia reduced-sugar can listed by ASDA Groceries still contains 7.4g sugars per 100g.
Use the pack’s per-100g figure and the quantity going into your recipe rather than relying on the front-of-pack claim alone.
Sainsbury’s describes the 1kg Ambrosia Light carton as having 30% less sugar and fat than standard Ambrosia Devon Custard. That comparison should not be assumed for the separately listed 400g can.
Match the claim and nutrition panel to the pack size and format you are buying.
Tesco’s no-added-sugar instant mix needs boiling water, while Bird’s Original is a traditional custard powder. Neither comes ready to pour from a tin.
Use a powder where the recipe allows you to prepare the custard separately, and follow that product’s directions.
The Ambrosia tin contains milk, Tesco’s instant mix contains milk-derived ingredients, and Bird’s Original Custard Powder may contain milk.
If milk is a concern, read the current pack’s ingredients and allergen statement before purchase and use, including any “may contain” wording.
Its reduced-sugar range includes both a 400g prepared custard can listed by ASDA Groceries and a separate 1kg Light carton listed by Sainsbury’s.
Tesco No Added Sugar Instant Custard Mix is a powder option when making custard separately fits the recipe.
Bird’s Original Custard Powder is relevant when a baking recipe specifies traditional custard powder.
This prepared Ambrosia custard is a carton option for recipes that do not require a tin. Check the recipe’s texture and heating requirements before using it in a baked component.

Consider this prepared custard if your dessert or recipe accepts a carton instead of a tin. Sainsbury’s describes the matching 1kg Light carton as having 30% less sugar than standard Ambrosia Devon Custard. Check the current pack’s nutrition panel and confirm that prepared custard suits your baking method.
No. ASDA Groceries lists 7.4g sugars per 100g for the 400g Ambrosia Light Low Fat & Reduced Sugar can. Use the nutrition panel and the amount your recipe calls for when comparing packs.
Only if the recipe allows custard to be made separately rather than requiring a prepared tin. Tesco’s instant mix needs boiling water and contains sucralose, so check both the method and ingredients before substituting it.
Read the current ingredients and allergen statement, including precautionary wording. The Ambrosia reduced-sugar tin contains milk, Tesco’s no-added-sugar mix contains milk-derived ingredients, and Bird’s Original Custard Powder may contain milk.
Check the specific recipe’s texture and heating instructions before using it that way. Tesco Real Food features desserts made with tinned custard, but that does not establish that a prepared tin will behave like custard powder in every baked filling or set layer.
