1. 1

   Place the mustard seeds in a small pot. Cover with cold water. Bring to a boil. Simmer for 2 minutes, stirring occasionally. Drain the mustard seeds and discard the cooking water. Repeat this process two more times.

2. 2

   In the same pot, bring the vinegar, water, sugar and salt to a boil. Mix until the sugar has dissolved. Add the mustard seeds. Simmer over low heat for 5 minutes. Remove from the heat.
