Organic Yellow Mustard Powder Mild sharpness, great for curries, mayonnaise and salad dressings. Steenbergs sources the highest quality organic Yellow Mustard Powder which we pack in small batch runs in North Yorkshire. This ground yellow mustard has a sharp and bitingly hot flavour, but not pure heat, so it s got a savoury smoothness to it as well. Tips to use: to get a decent heat, add cold water and mix. Then leave it 10 or so minutes to develop and then use. If you want its heat rather than flavour, you must add mustard at the end because its heat disappears with time and cooking. Or perha

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as STEENBERGS LIMITED, number 04316848. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
The company describes its own premises: "It was set up in 2003 by Axel and Sophie Steenberg (pictured) in North Yorkshire. We have moved three times since set up and are now in a purpose-built, ecofriendly factory, but still just 200 yards from where we started" Self-declared (§3.3), read from the company's site. Source.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
No majority shareholding traced outside the UK. Companies House.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
