Dijon mustard

French mustard the dark brown one is the basis for Steak Diane sauce mmmm

I like the Maille Dijon mustard à l'ancienne. Very tasty.

I love French mustard on cheese on toast.

I much prefer French or German mustard to English which I find is too sharp.

Dijon is made with French seeds and wine vinegar, flavour is not as brown mustard.

I was in Asda not long ago when an elderly man asked an assistant where the Dijon mustard was.
She said, ‘Oh, we don’t stock that any more.’

I was about to queue at the checkout, ditto the elderly man, but I thought that surely couldn’t be right, so I went and looked.
Three different brands of Dijon mustard at more or less eye level on the shelf!
So I showed him.
I couldn’t help wondering whether the assistant had just never heard of it, so assumed they didn’t have it - perhaps more charitable than thinking she just couldn’t be bothered.

I think I need to get hold of some Dijon. I've never been interested in making sauces etc before. Lockdown has had some strange effects on me.

As others have said I think "french" mustard is smooth like english mustard but a darker colour.
I've still got a pot of Moutarde Ancienne from our years in France. It's a dark colour, packed with dark whole mustard seeds. I can't read the ingredients on the label. It's milder in flavour than english mustard such as Colmans
I use it to make a salad dressing .Plus vinegar honey and olive oil.
Maybe the mustard plants that grow in France are different from those in England.

Dijon mustard is dark yellow and it is French but French mustard (my favourite) is dark brown
