Dijon mustard is simply a prepared mustard made of brown mustard seeds, white vinegar and/or white wine, preservative(s), usually citric acid, turmeric to enhance colour and seasoning(s). The ingredients added will depend on the brand.
There are several brands and styles of Dijon mustard (for example: old fashioned or Old style Dijon, creamy Dijon, original Dijon, honey Dijon, just to mention a few).
Canada is the largest producer and exporter of brown mustard seeds. (Mustard Production for Alberta).
Why is it called Dijon Mustard?
The very original Dijon mustard was made in the City of Dijon in France. The company was started by François Naigeon in 1703 and later registered as “Amora” in 1919. After several changes, the plant was bought by Unilever in 2000, and later closed in 2009, when all production was moved to the neighbouring City of Chevigny-Saint-Sauveur, which is currently the largest production site for European Condiments (Dijon mustard, mayonnaise, gherkins and vinegar) (L’usine nouvelle).
The original Dijon mustard was blended with verjuice. (Wiki Cookbook)
Since Dijon mustard does not have a Protected Designation of Origin, the name is generic, which means mustard can be produced anywhere in the world and be labelled as Dijon mustard.

I know, it’s been awhile. Busy doesn’t begin to cover it! Hahaha…but we all are busy right? Hope you are well dear! Koko
I am good. I am so glad to know you’re still blogging. Have a pleasant week!

I wish I could be on here more. I am trying to make a point to do so. I have a couple acres I tend to and 15 rescued or foster pets I care for by myself. That along with various projects a house and property always needs, keeps me insanely busy. I’m doing something the moment my eyes open until I’m too sleepy to think and even in dream state, I believe my brain is working overdrive! Hahaha. You are a doll to remember me and I thank you kindly for that. Be well Liz. 🙂
Of course I remember you. How can I not!!! I am so glad you’re rescuing pets. How kind of you.
Life is busy for everyone, but can you imagine what it would be like if you had nothing to do?
I am not blogging as much as a used to but I try to post s’thing small everyday. I’ve taken a break from cooking. I’ll start again, soon, but just one post in a week! Enjoy the rest of the week!

I imagine it all the time! Haha. Time is something we can’t get back. I am joyful I can help the animals. I do love them. Somehow these strays find me and the answer is always yes I can take another in.
So what’s been keeping you busy these days?
Just posting on ingredients and cooking twice a week. I don’t want to stop blogging completely but I don’t have enough time for cooking! Have a great week!
Liz
