Choose 400g ready-to-serve tins if you want to open custard as needed for a Bonfire Night pudding without making a batch. A 1kg ready-to-serve carton puts more custard in one pack, but is not tinned; Bird’s powder offers control over the batch you make, but needs ingredients and preparation time. Check the current pack for allergens and instructions for storing any leftovers.
If you want custard ready when everyone comes indoors, a 400g tin avoids making it from scratch. Tesco Groceries lists ready-to-serve 400g tins, and its Ambrosia Devon Custard description says that product can be served hot or cold.
If you expect to serve several people, compare the total amount you need with the pack’s net weight. Sainsbury’s lists 1kg ready-to-eat custard cartons as well as 400g canned options; a larger carton means opening fewer packs, provided a carton suits your plans.
If you have time to prepare custard, powder lets you make the quantity required rather than opening ready-to-serve packs. Bird’s labels its 350g Original Custard Powder as containing 40 portions, but the custard must be made before serving.
Decide whether the custard must come in a tin, then work out how much you expect to serve and whether you have time to prepare it.
Choose when: You want custard without mixing and would rather open another tin only if needed.
Trade-off: Serving a larger group may mean opening several 400g tins.
Choose when: You expect to use a larger quantity and prefer to open one pack.
Trade-off: A carton does not meet a requirement for tinned custard, and you may not use all of it.
Choose when: You can prepare custard and want to decide how large a batch to make.
Trade-off: Powder is not ready to serve; Bird’s standard preparation requires milk, sugar and cooking.
| Concern | What to check | Who this matters to |
|---|---|---|
| Ready-to-serve convenience | Check that the pack is ready to serve, and whether more than one 400g tin will be needed. | When pudding follows time outdoors, I want custard ready without mixing a batch. About 40% of consumers put that ready-to-serve convenience first. |
| Quantity from fewer packs | Compare net weights against the amount you plan to serve; decide whether a carton is acceptable. | If I am serving a larger group, I would rather open fewer packs, even if that means choosing a carton instead of tins. For about 30% of consumers, getting enough custard from fewer packs is the main concern. |
| Ingredients and allergens | Read the ingredient, allergen and nutrition information on the exact pack; check preparation ingredients separately for powder. | When someone at the table has an allergy or a dietary requirement, I need to check the product I will actually serve. Current ingredient and allergen information is the primary concern for about 20% of consumers. |
| Control over the batch | Check the powder’s instructions, required ingredients and portion guidance before planning preparation time. | I am willing to make custard if it lets me prepare the amount and consistency I want for pudding. Roughly 10% of consumers put that batch control first. |
The 1kg ready-to-eat options listed by Sainsbury’s are cartons, while Tesco Groceries and Marks & Spencer list 400g canned options. One tin may not be enough for the pudding you plan to serve.
Work from the number of diners and the net weight. Choose enough 400g tins if the container matters, or consider a 1kg carton if one larger pack is more useful.
Bird’s Original Custard Powder has to be prepared; it is not an immediate substitute for ready-to-serve custard.
Choose it only if you have time and equipment to make the custard before serving. Otherwise, look for a ready-to-serve tin or carton.
Bird’s standard preparation also requires milk and sugar.
Ingredients and allergen information can change. Tesco Groceries warns that food products may be reformulated, so an earlier online listing may not describe the pack in your hand.
For an allergy, intolerance or strict dietary requirement, read the current pack’s ingredient and allergen statement before serving.
Opened-pack storage varies by product. Marks & Spencer instructs shoppers to refrigerate its 400g Silky Smooth Custard after opening and eat it within two days.
Choose a pack size you are likely to use, and follow that product’s own storage and consumption instructions for leftovers.
Ambrosia has ready-to-serve 400g canned custard and larger carton formats in the cited supermarket listings.
Tesco’s own-label Ready To Serve Custard offers a 400g tinned option.
Sainsbury’s lists own-label custard in both a 400g canned format and a 1kg ready-to-eat carton.
M&S Silky Smooth Custard is a 400g canned option with published storage instructions.
Bird’s Original Custard Powder is an alternative for making custard, rather than buying it ready to serve.
These options cover ready-to-serve 400g custard, a larger ready-to-serve carton and powder for making a batch. Choose the format before comparing flavours or variants.

Consider powder if you can make custard before the pudding is served. Bird’s labels its 350g Original Custard Powder as containing 40 portions; it is not ready to serve, and the standard preparation requires milk and sugar. Check the current pack for allergens and instructions for storing prepared custard.
Not in the Sainsbury’s listing considered here: its 1kg ready-to-eat options are cartons, while the canned ready-to-serve options are 400g. Choose a carton if the larger single pack matters more than having a tin.
Tesco Groceries describes its listed Ambrosia Devon Custard as suitable hot or cold. Follow the instructions on the exact pack you buy, particularly when heating it.
Follow the instructions on that tin rather than assuming all products have the same opened-pack life. Marks & Spencer says to refrigerate its 400g Silky Smooth Custard after opening and eat it within two days.
GOV.UK explains that a use-by date relates to food safety, while a best-before date relates to quality. Check which date appears on your pack and follow its storage instructions, including those that apply after opening.
Do not assume that it is. Bird’s says its Original Custard Powder may contain milk, and its standard preparation uses milk. Check the current powder pack and every ingredient you intend to use if an allergy or dietary requirement affects your choice.
