For a toddler dinner, compare salt per 100g on the exact tin, then consider the amount you plan to serve; a product name or label such as “light” does not establish that it has less salt. Tesco Ready To Serve Custard and Sainsbury's Stamford Street Co. Custard each declare 0.10g salt per 100g. Check the current ingredients and allergen declaration too: their listed recipes contain milk ingredients, but custard recipes differ and should not all be assumed to contain egg.
Who is choosing it?
Carers comparing salt
Parents and carers planning dinner for a child aged 1–3 who want to compare the salt in a realistic serving, not just a figure for a larger pack serving. Derbyshire Family Health Service advises against adding salt to young children's food or giving them salty foods.
Carers checking allergens
Anyone who needs to check whether the exact custard contains egg or milk. The Tesco and Stamford Street Co. tins list milk ingredients; the separate M&S chilled custard lists egg yolk. The current label matters more than an assumption about custard as a category.
Households planning small portions
Carers considering a 400g tin who may have custard left after dinner. Tesco and Sainsbury's give different refrigeration and use-after-opening instructions for the tins described here, so the remainder needs a product-specific plan.
What matters when buying?
Start with the current tin's salt and allergen information, then decide whether its size and opened-can instructions work for your household.

Buying pitfalls
-
Assuming every custard contains egg
Tesco Ready To Serve Custard and Sainsbury's Stamford Street Co. tinned custard list milk ingredients without egg in their listed recipes. M&S Collection Madagascan Vanilla Luxury Custard is a different, chilled product that lists egg yolk.
Check the full ingredients and allergen declaration on the current pack before serving the exact product.
-
Using “light” or a brand name as a salt comparison
Those descriptions do not replace a like-for-like salt figure. Tesco and Stamford Street Co. each declare 0.10g salt per 100g for the 400g tins discussed here.
Compare current labels per 100g first, then consider the portion you will serve.
-
Overlooking opened-can instructions
Tesco says to transfer and refrigerate unused custard from its 400g tin and consume it within 3 days. Sainsbury's says to transfer and refrigerate leftovers from its Stamford Street Co. 400g tin and use them within 1 day.
Before choosing a tin, check whether you can use the remainder within that product's stated period.
A tin that cannot be used within its stated storage period may leave custard to discard.
