Pickled mustard seeds are also known as Poor Man’s Caviar due to its texture which is similar to that of caviar. It is a tongue in the cheek expression for having a rich man’s taste but a poor man’s budget. See Poor Man’s Caviar (Aubergine Pate) for a paté recipe that looks similar to caviar, but does not have the same price tag.
1 cup white vinegar
1 cup water
1 cup sugar
1 tablespoon dry mustard powder
½ cup whole yellow mustard seeds
- In a saucepan, bring everything but the mustard seeds to a boil.
- Add the mustard seeds and simmer for 5 minutes, until the seeds bloom (or roughly double in size).
- Remove from heat and let cool. Store the seeds in the liquid in the refrigerator for up to two weeks.
