If you ever tried to buy mustard without any additives, you know already that it's nearly impossible to find any. Here are some of the most common ingredients in mustard products:

  • Dijon Originale Mustard from Maille: Water, mustard seeds, vinegar, salt, citric acid, sulphur dioxide.
  • Honey Dijon Mustard from Maille: Sugar, water, vinegar, mustard seeds, honey (8%), salt, spices, coloring agent: caramel, acidifier: citric acid, preservative: potassium metabisulfite.
  • Colemann's English mustard: Water, Mustard Flour, Sugar, Salt, Wheat Flour, Spice, Citric Acid, Stabiliser (Xanthan Gum).

Not all the additives are necessarily harmful but some may cause allergic reactions, so why not avoid them altogether? That's why I like making my own mustard, ketchup and other ingredients. Many of them are included in my apps and book but some can also be found on my blog.

Making mustard at home is easier than you may think. It takes just a few minutes to prepare and lasts in the fridge for months. For best taste, I'd recommend you leave the mustard in the fridge for at least 10-14 days before you start using it.

Ingredients (makes ~ 2 cups, 500g / 17.6 oz)

Classic yellow mustard
  • 1 cup mustard powder (120 g / 4.2 oz)
  • 1 medium or 2 small white onion (110 g / 3.9 oz)
  • 2 cloves garlic
  • 1/4 cup white wine vinegar (60 ml)
  • 1/2 cup water (120 ml)
  • 1 cup dry white wine OR 1/4 cup white wine vinegar + 3/4 cup water. Do not substitute wine if making Dijon mustard
  • 1 tbsp extra virgin olive oil
  • 1 tsp pink Himalayan salt or sea salt
  • optional: 5 drops stevia or more to taste
Dijon mustard
  • same as Classic yellow mustard plus
  • 2-5 dashes tabasco
  • 1 tsp turmeric
  • pinch of black or white pepper (significantly improves absorption of turmeric)
Wholegrain mustard
  • same as Classic yellow mustard but
  • only 1/2 cup mustard powder (60 g / 2.1 oz)
  • 3/4 cup mustard seeds, whole (120 g / 4.2 oz) - I used a mixture of yellow and brown
Other options
  • 1/4 cup fresh herbs: tarragon, basil, parsley, oregano, thyme, etc.
  • 1-4 tbsp grated horseradish (depends on how spicy you like it)

Note: The garlic and onion are only used to infuse the wine, so I only counted 25% of the nutritional values for these ingredients. When looking for ingredients, try to get them in their most natural form (organic, without unnecessary additives).


Classic yellow & Dijon mustard:

  1. Peel and roughly chop the onion and garlic and place in a non-reactive saucepan.
    What is a non-reactive saucepan? It's a saucepan made of a material that will not react with acidic ingredients. For example, stainless-steel is non-reactive, whereas copper is a reactive material that will esily become worn off if used with acidic ingredients (lemon juice, vinegar, etc.).

  2. Pour in the white wine, white wine vinegar and water and bring to boil over medium heat. Simmer for just about 5 minutes. Keto & Paleo Mustard - Three Ways
  3. Cool, strain and discard the solids.

  4. Place the mustard powder into a saucepan and add the strained liquid. Mix until well combined. Cook over low-medium heat until it thickens. Keto & Paleo Mustard - Three Ways
  5. Add stevia (if used), extra virgin olive oil and season with salt. If you're making Dijon mustard, also add the turmeric and tabasco and blend in well. Keto & Paleo Mustard - Three Ways
  6. Place in a jar and keep refrigerated for up to 6 months. The mustard will taste best after a few weeks of "ageing".

Wholegrain mustard:

  1. Instead of 1 cup of mustard powder, use just half of it. Keto & Paleo Mustard - Three Ways
  2. In a blender, roughly chop the mustard seeds. Do not over process. Keto & Paleo Mustard - Three Ways
  3. Follow the same steps as for the yellow / Dijon mustard. Again, you will need to keep the mustard in the fridge for about 2 weeks before it's ready. Keto & Paleo Mustard - Three Ways

Other options

You can use freshly chopped herbs or grated horseradish. Simply stir in when the mustard is done. The amount of horseradish depends on how strong you want the mustard to be. I like to use 2-3 tablespoons, which makes it quite spicy but not too hot. Keep in mind the flavour will change as you leave the mustard to age in the fridge and the spiciness will slightly drop.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

How long should this take to thicken? It's burning my eyes.  Is that normal? Anyway to prevent that?


The mustard powder can be quite strong. What helps is what I do when chopping onion - if there is any way you can block your (e.g. with a tissue) nose it helps 😊 It shouldn't take long to thicken - just a few seconds but if you leave it for 5-10 minutes it will thicken more.


What type of mustard powder do you use? The powder I tried came out extremely hot, like hot English mustard.


Hi Joshua, that's the one I used too (English mustard powder) and it is quite hot. You could get mustard powder on Amazon but make sure to check the reviews if you prefer your mustard mild.


Your directions say to age the mustard in the fridge...  Is it ok to remove it from the fridge after aging and store it in the pantry until needed, or does it need to stay in the fridge?  Alternatively, can it be aged in the pantry (how cold does it need to be)?  My fridge space is limited.   Thanks for the recipe. It sounds tasty.


Thank you Dave! I would keep it in the fridge at all times. Maybe instead you could freeze part of it in an ice cube tray?


Hi. I am wondering whether there are substitute for white wine and wine vinegar?


Yes, you can use apple cider vinegar instead of white wine vinegar.


I'm avoiding all vinegars right now - would lemon juice or some other ingredient work? I know it would alter the taste - what say you?


Yes, I think that lemon juice is a good alternative. It may result in a slightly different taste. I haven't tried that but I guess it should work.


Is there a newsletter or way to follow by email?


Hi Jann, we don't collect e-mail addresses to send newsletters but you can use an RSS reader (link in the footer) to follow all my posts 😊


Thanks for all the great tips! I tried 2 tbsp of horseradish and it was way too much for me. I guess I may be sensitive to very spicy food. I'd say 1/2-1 tbsp is enough but maybe it will not be as spicy in a week or two. I just tried it right after I made it.


Melanie, I think it will get less spicy after 2-3 weeks but it is better if you just use less. I like it quite spicy 😊


This looks so easy! Thanks :-D


You're welcome, Meg! hope you like it 😊


My fav is definitely Dijon but I'm wondering how the herbs taste. which one would you recommend?


Hi Jimmy, you should definitely try tarragon! 😊
