After delving into making my own versions of mayo and ketchup, I figured it was time to start making my own mustard too. After reading a few different methods and about mustard making generally, I decided to give it a shot. At its root, making mustard requires mixing ground mustard seeds with water. The colder the water, the sharper the mustard will be. Allowing the mixture to chill in the fridge overnight is supposed to do away with the bitterness from the mustard seeds. That's it. Anything else is extra, and all down to personal choice and flavouring. Here's what I did. I opted for warmish water as Little Bit really likes mustard but not if it's too strong. I made two different flavours: mix spice and orange tarragon.
2 c yellow mustard seeds
3/4 c warmish water
1/2 c apple cider vinegar
2 tsp olive oil
salt to taste
For the mix spice variant:
1 tsp mix spice
a pinch of brown or maple sugar
For the orange tarragon variant:
1 tsp dried orange peel
1 1/2 tsp dried tarragon
1) Coaresly crack about 3/4 c mustard seeds. Set aside. More finely grind the remaining mustard seeds. How finely ground these are and how many are left coarser will affect the final texture of your mustard. Combine all the mustard in a bowl. Add salt and water. Stir. Add vinegar and olive oil, then refrigerate overnight.
2) Check the texture of the mustard and taste test. Add a little more water or vinegar as necessary. Then divide the mixture in half and add the remaining ingredients for each variant to one-half of the mustard. Allow to sit overnight again for flavours to develop.
3) Taste test and serve.
To test these out, I made Clair Saffitz's brioche pigs in a blanket, along with a fresh batch of Beetroot Ketchup and some rosehip vinegar mayo. I was thoroughly pleased with these two mustards, and delighted to have finally gotten around to making my own. I can't believe how easy it was! I even got help grinding up my seeds in the mortar and pestle from Little Bit, who was very proud to have helped. The whole time I was making these, I was thinking of my grandmother who passed three years ago. Ahe loved mustard and took great delight in finding and trying new flavours and varieties. This is something we had talked about doing together but never got to.
