For a larger Sunday-roast table, a 1kg ready-to-serve pack reduces preparation; Sainsbury's labels its 1kg custard as eight servings, but that guide should not be assumed for every pack. Choose smaller tins if you would rather open custard as needed, or powder if you have time to make it and want to adjust the recipe. Check the exact product's ingredients, heating directions and storage instructions before serving.
If dessert needs several portions and you want little last-minute preparation, a ready-to-serve pack is worth considering. Sainsbury's labels its 1kg custard as eight servings and provides hob and microwave heating directions.
If ingredients, allergens or storage directions affect what you can serve, check the exact pack rather than relying on another custard's label. GOV.UK guidance covers ingredients, net quantity and relevant storage information on packaged food.
For a Sunday-roast dessert, settle the portion size first, then decide how much preparation you can accommodate and which product labels you need to check.
| Concern | What to check | Who this matters to |
|---|---|---|
| Portions and leftovers | Compare the pack weight and its own serving guide; read its instructions for storage after opening. | If I am serving several people, I need enough custard without opening more than I can use. About 42% of consumers put portion planning first. |
| Preparation | Check whether the product is ready to serve or needs milk, sugar and cooking. | When the roast already needs my attention, I would rather pour or heat custard than make a separate batch. Around 33% of consumers put preparation time first. |
| Ingredients and labels | Read the exact pack's ingredients, allergen declaration and nutrition information per 100g. | If guests need particular ingredients checked, I need the label for the custard I will actually serve. Roughly 25% of consumers put ingredient and label fit first. |
A 1kg pack may simplify serving a larger table, but an opened pack needs to be used within its own stated storage period.
Use the pack's serving guide to plan portions, then check its refrigeration and use instructions before choosing the size.
Bird's custard powder needs milk, sugar, heating and stirring, which adds a preparation step while you are timing the roast.

It may be enough, depending on the number and size of portions. Sainsbury's labels its Ready To Eat Custard 1kg as eight servings; use the serving guide on the particular pack you buy and allow for any second helpings.
