Regular pudding makers
If custard often goes with crumble, sponge or fruit, choose a pack size you can use within its instructions for storage after opening.
Who is this for?
Low-effort dinner cooks
Ready-to-serve custard avoids the mixing step required for instant powder. The checked Tesco, Sainsbury's and Ambrosia ready-to-serve products can be served hot or cold; follow the heating directions on the pack.
Nutrition-panel readers
If sugar and fat affect your choice between recipes, compare the figures per 100g. Ambrosia describes its Light Devon Custard as having 30% less sugar and fat than its standard Devon Custard, rather than being sugar-free.
What matters when choosing?
| Concern | What to check | Who this matters to |
|---|---|---|
| Pack size and leftovers | Check the net weight and instructions for storing custard after opening. | If custard accompanies several puddings, I want a pack I can finish while it is still suitable to use. About 42% of consumers put pack size and leftover planning first. |
| Preparation and serving | Check whether it is ready to serve or needs mixing, and follow the product's heating directions. | When dinner is nearly ready, I would rather open custard than prepare powder with boiling water. Minimal preparation is the main need for about 33% of consumers. |
| Standard or light recipe | Compare sugars and fat per 100g, including what a light claim is compared with. | If I am choosing between standard and light custard, I want to read the nutrition panel rather than rely on the variant name. Roughly 25% of consumers place that comparison first. |
Checks before you buy

Assuming every ambient custard is ready to pour
Ready-to-serve custard can be eaten cold or heated, but Bird's Instant Custard needs boiling water, mixing and a short standing time.
Check the preparation directions if you need custard ready as soon as the pudding is served.
-
Putting an opened tin back in the cupboard
The checked products require refrigeration after opening. The checked M&S tin specifies use within two days; the checked Tesco, Sainsbury's and Ambrosia products specify three days.
Follow the instruction on your pack, including any direction to move leftovers out of the can.
A pack that is too large for your plans may leave custard you cannot use within its stated period.
-
Assuming shelf-stable custard contains no milk
The checked Tesco, Ambrosia, M&S and Bird's products declare milk or milk-derived ingredients. The Food Standards Agency identifies milk as an allergen.
If you need to avoid milk, read the ingredients and allergen statement on the current physical pack rather than relying on its storage format.
Brands to consider
Tesco
Own-label ready-to-serve custard includes a 400g tin and a separate 500g carton.
- The tin offers a ready-to-serve option for a cupboard pudding.
- Check the container and the current pack label if you specifically want a tin or need ingredient information.
Ambrosia
Its Devon Custard range includes standard and light 400g tins as well as other flavours and formats.
- The standard 400g tin can be served hot or cold.
- According to Ambrosia, its light version has 30% less sugar and fat than its standard Devon Custard. That comparison does not mean it is sugar-free.
Sainsbury's
Its ready-to-eat ambient custard comes in a 500g carton rather than a tin.
- It can be served hot or cold.
- Sainsbury's instructs customers to refrigerate it after opening and consume it within three days.
M&S
Its Silky Smooth Custard is a 400g tin made with whole milk, according to M&S.
- The tin format suits shoppers who specifically want a canned custard.
- M&S instructs customers to refrigerate it after opening and eat it within two days.
Bird's
Instant custard is an alternative for cooks willing to make custard rather than open a ready-to-serve tin.
- Its instant sachet is prepared with boiling water, mixing and a one-minute stand.
- It does not provide the immediate pour-and-serve convenience of a ready-to-serve tin; check the pack's allergen declaration.

Common questions
Does ready-to-serve tinned custard need cooking?
No. The checked Tesco and Ambrosia ready-to-serve products can be eaten cold or heated. Follow the individual directions when warming them, including transferring custard out of the can before heating.
How should I store custard after opening?
Refrigerate it and follow the period stated on its pack. The checked Tesco, Sainsbury's and Ambrosia products specify three days after opening; the checked M&S tin specifies two days.
Can I assume tinned custard is free from milk?
No. The checked Tesco, Ambrosia and M&S custards declare milk or milk-derived ingredients. Read the current pack's ingredients and allergen statement if you need to avoid milk.
Is Ambrosia Light Devon Custard sugar-free?
A light claim does not mean sugar-free. Ambrosia describes its Light Devon Custard as having 30% less sugar and fat than its standard Devon Custard; check the current nutrition panel for the variant and portion you are considering.
Can instant custard take the place of a ready-to-serve tin?
Yes, if its preparation fits your dinner plans. Bird's Instant Custard needs boiling water, mixing and a one-minute stand, whereas a ready-to-serve tin needs no mixing before serving cold.
