Step 1

Add the mustard seeds and liquid to a large glass jar. Give it a solid shake and seal it up.

Step 2

Set into a dark place like the cupboard for a day or 2 to allow the seeds to absorb the liquid.

Step 3

Process the mixture in a food processor with your extra ingredients. Adjust with a bit of salt, if desired. You can add in a bit of water if you feel the mustardis too thick.

Step 4

Return the finished mustard to the jar and seal.
