Salt-first tea-time planners
Parents and carers who want to compare ready-to-serve tins on the same per-100g basis, then account for the amount they intend to serve.
Who these checks matter to
Allergen-label checkers
Families who need to inspect the ingredients and allergen declaration on the exact can before serving, rather than rely on a general description of custard.
Ready-to-serve shoppers
People choosing a tin for tea time who need to plan portions and follow the product’s instructions for any custard left after opening.
What to check when choosing a tin
Start with salt per 100g for a like-for-like comparison, then check the exact can’s allergen label and how much custard you will use.
| Concern | What to check | Who this matters to |
|---|---|---|
| Salt | Compare salt per 100g, then check the amount for the portion you intend to serve. | If salt is my main concern at tea time, I want to understand what the child’s serving contains; about 33% of consumers put salt first. |
| Allergens | Read the ingredients and allergen declaration on the exact can before serving. | When a child must avoid a particular ingredient, I need the label for the tin in hand, not an assumption about custard; about 42% of consumers prioritise allergen certainty. |
| Portions and storage | Check the tin size, stated portions and instructions for opened contents. | If I will use only part of a tin, I need a serving plan that also accounts for leftovers; about 25% of consumers place ready-to-serve convenience and portion planning first. |
Mistakes to avoid
-
Reading “low fat” as “reduced salt”
Tesco Groceries lists Ambrosia Low Fat Custard at 2.0g fat and 0.12g salt per 100g. Its salt figure is higher than the listed figures for Tesco Ready To Serve Custard and standard Ambrosia Devon Custard.
Compare the salt line separately, then consider fat, sugars and the portion you intend to serve.
-
Assuming every tinned custard contains egg
A category-level statement cannot establish the ingredients of an individual tin. The checked Tesco and Ambrosia product information identifies milk-containing ingredients, but an allergy decision needs the current label of the exact product.
For any food allergy, inspect that can’s ingredients and allergen declaration before purchase and serving.
-
Comparing salt per portion without comparing portions
Tesco Groceries gives 0.20g salt for a 200g half-can of its Ready To Serve Custard; Joybuy gives 0.14g for a 130g portion of Ambrosia Devon Custard. Those serving sizes differ.
Use the per-100g figures to compare tins, then look at the amount for the serving you plan to use.
-
Overlooking the instructions after opening
Opened-custard instructions affect what to do when tea time uses only part of a tin. Tesco Groceries instructs shoppers to transfer its unused custard to a non-metallic container, cover and refrigerate it, and consume it within three days.
Follow the instructions on the exact tin and keep track of when it was opened.
Brands and product lines to consider
Tesco
Tesco Ready To Serve Custard is a 400g tinned option for comparing salt and planning a half-can serving.
- Tesco Groceries lists 0.10g salt per 100g and 0.20g per 200g half-can.
- Its ingredient information includes milk; check the current can’s full label if allergens matter.
Ambrosia
The checked Ambrosia 400g tins include standard Devon Custard and Low Fat Custard, which serve different reasons for choosing a product.
- Joybuy lists standard Devon Custard at 0.11g salt per 100g; Tesco Groceries lists Low Fat Custard at 0.12g.
- Low-fat wording concerns fat, not salt. Check the exact variant’s nutrition and allergen label.
Bird's
Bird’s Original Custard Powder is a make-at-home alternative if a ready-to-serve tin is not essential.
- Tesco Groceries lists 0.15g salt per 100g when prepared with semi-skimmed milk as specified.
- It is not tinned custard, and its prepared nutrition depends on how it is made.

Questions about tinned custard
What does “low salt” mean when comparing these tins?
NHS inform defines low salt as 0.3g or less per 100g. The listed Tesco Ready To Serve, Ambrosia Devon and Ambrosia Low Fat tins are each below that threshold, but this classification does not establish a reduced-salt claim or tell you how much to serve a particular child.
Does low-fat custard contain less salt?
Not necessarily. Tesco Groceries lists Ambrosia Low Fat Custard at 0.12g salt per 100g, compared with 0.10g for Tesco Ready To Serve Custard; Joybuy lists standard Ambrosia Devon Custard at 0.11g. Compare salt separately from fat.
Does every tin of custard contain egg?
You cannot determine an individual tin’s egg status from the category name. The checked Tesco and Ambrosia information identifies milk-containing ingredients, but anyone buying for an egg or other food allergy should inspect the exact can’s current ingredients and allergen declaration before purchase and serving.
How should I keep custard left after opening a tin?
Follow that tin’s instructions. Tesco Groceries says to transfer unused Tesco Ready To Serve Custard to a covered, non-metallic container, refrigerate it and consume it within three days; the checked Ambrosia Low Fat and Strawberry Flavour instructions also specify refrigeration and use within three days after opening.
