Salt-label comparers
New-parent households choosing a cupboard dessert for adults or older children can compare the declared salt per 100g. Ambrosia’s standard and Light Devon Custard tins show why the variant name alone is not enough.
Who needs which checks
Quick-dessert households
Parents who want ready-to-serve custard can choose a pack size with the leftovers in mind. Ambrosia and Sainsbury’s direct shoppers to refrigerate opened custard and consume it within three days.
Baby-feeding cautious shoppers
Parents considering sharing a household dessert with a baby need a separate feeding decision, not just a salt comparison. NHS guidance says babies should not eat much salt and do not need sugar or sweeteners.
What matters when choosing tinned custard
Decide who the custard is for, then compare the exact variant’s salt label and a pack size the household can use after opening.
| Concern | What to check | Who this matters to |
|---|---|---|
| Salt declaration | Compare salt per 100g on the same basis and check the exact variant. | If salt is my deciding factor, I want to compare ready-to-serve tins by their labels rather than by names such as “light”; about 33% of consumers put that comparison first. |
| Baby-feeding suitability | Consider the baby’s age and feeding stage; read the sugars and milk-allergen information. | When a household dessert might be shared with a baby, I need to settle the feeding question separately from the salt figure. For about 33% of consumers, that is the primary concern. |
| Serving and leftovers | Check whether the product is ready to serve and follow its post-opening storage instructions. | I want dessert without making custard from scratch, but I also need to use what remains after opening; roughly 20% of consumers prioritise that combination. |
| Pack and format fit | Check pack weight and whether a powder needs additional ingredients and preparation. | If the household will use only a little custard at a time, the amount and preparation work matter most to me. Around 14% of consumers make that their main consideration. |
Mistakes to avoid
-
Assuming “light” means less salt
Ambrosia declares 0.12g salt per 100g for Light Devon Custard, compared with 0.11g for its standard Devon Custard. The Light product’s reduced sugar-and-fat claim is not a salt comparison.
Read the salt, sugars and fat entries separately on the variant you intend to buy.
-
Treating household custard as baby food
A comparatively lower salt figure does not establish suitability for a baby. NHS guidance says babies should not eat much salt and do not need sugar or sweeteners.
Use age-appropriate feeding guidance for the baby rather than choosing a household custard on its salt figure alone.
-
Opening a large pack without a plan for leftovers
Ambrosia and Sainsbury’s instruct shoppers to refrigerate opened custard and consume it within three days.
Choose an amount the household can use within the period stated on the pack, and follow its storage directions.
Custard left unused beyond those directions may have to be discarded.
-
Planning around a tin that may not be available
Tesco’s Stockwell & Co. Custard declares 0.10g salt per 100g, but the listing reviewed for this comparison described it as out of stock.
Check current availability before relying on that particular tin; compare the labels of available alternatives if needed.
Relevant brands and formats
Ambrosia
Ambrosia lists standard and Light Devon Custard in 400g ready-to-serve tins.
- The standard tin declares 0.11g salt and 10.6g sugars per 100g; the Light tin declares 0.12g salt and 7.4g sugars per 100g.
- Both contain milk. Ambrosia directs shoppers to refrigerate leftovers and consume them within three days.
Tesco / Stockwell & Co.
Stockwell & Co. Custard is a 385g ready-to-serve tin listed by Tesco.
- Tesco declares 0.10g salt per 100g for this tin, below the declarations for the Ambrosia and Sainsbury’s tins discussed here.
- It contains milk; check the current listing for availability before planning to buy it.
Sainsbury’s
Sainsbury’s Ready To Eat Custard comes in a 500g ready-to-serve pack.
- Its label declares 0.15g salt and 10.7g sugars per 100g, allowing a per-100g comparison with the named tins.
- It contains milk and must be refrigerated after opening and consumed within three days.
Bird’s
Bird’s Original Custard Powder is a make-at-home format, not a ready-to-serve tin.
- The preparation instructions specify milk and sugar, so shoppers can assess what making it involves.
- It requires heating and stirring; its prepared nutrition should not be compared with a tin without considering the stated preparation method.
M&S
M&S Collection Madagascan Vanilla Luxury Custard is a chilled custard made with Channel Island milk, British cream and egg yolks.
- As a chilled product, it is a different storage choice from a cupboard tin. Compare its nutrition panel before using it in a salt comparison.

Questions about tinned custard
Does “light” tinned custard mean less salt?
No: Ambrosia’s Light Devon Custard declares 0.12g salt per 100g, while its standard Devon Custard declares 0.11g. The Light variant’s sugar-and-fat claim does not establish a salt reduction, so compare the nutrition tables.
What does “low” salt mean on a food label?
NHS inform describes 0.3g salt or less per 100g as low. That label benchmark helps with comparisons; it does not establish whether a product is suitable for a baby or an individual dietary need.
Can I choose a lower-salt tinned custard for my baby?
Do not use a lower salt figure alone to decide that household custard is suitable for a baby. NHS feeding guidance says babies should not eat much salt and do not need sugar or sweeteners; follow age-appropriate feeding advice, and seek individual professional advice where a medical dietary need applies.
How should I keep custard after opening it?
Ambrosia and Sainsbury’s direct shoppers to refrigerate opened custard and consume it within three days. Ambrosia also says to remove remaining custard from the can; follow the instructions on the exact pack you open.
Is the ready-to-serve custard discussed here suitable for someone with a milk allergy?
Do not treat the named Ambrosia or Sainsbury’s dairy custards as milk-free: their product information identifies milk. Check the allergen statement on the exact pack before choosing any variant.
