Ingredients
1/3 cup mustard seeds
1/3 cup cider vinegar (I used white wine vinegar)
1 clove of garlic - halved
3 tablespoons water
3 tablespoons honey
1/4 teaspoon salt
pinch ground cinnamon.

Method:
Combine mustard seeds, vinegar and garlic in a small bowl. Cover and refrigerate for 36 hours.

Discard garlic (use in something else!! Full of extra flavour) and pour mustard mix into the bowl.
Add water and process till a coarse consistency. I did all up about 1 minute at speed 6-8. Stopped a few times to scrape down sides and check consistency.
Add honey, salt and cinnamon and mix 10 secs speed 4.

Really lovely mixed with TMX mayonnaise to make a seeded dijon mustard.

Hi Zan
I have just made some mustard using another thermomix recipe that had all the ingredients mixed in together including the garlic then left overnight.
I have found it very bitter and was hoping someone would know what I could add to take away the bitter taste.
