Think of this “caviar” as deconstructed mustard, and don’t think about serving smoked ham or other pork without it. The slow simmer in vinegar softens the mustard seeds to the crunchy-gooey texture of sturgeon caviar.
Step 1: Place the mustard seeds, vinegar, syrup, and ½ cup water in a heavy saucepan and stir to mix. Bring to a boil over high heat, then gently simmer, covered, over low heat until the mustard seeds are semisoft, like caviar, 30 to 45 minutes. Stir often and add water as needed to keep the mustard seeds from drying out.
Step 2: Stir in the prepared mustard, hot sauce, and salt and pepper to taste. The caviar should be highly seasoned. Simmer for 3 minutes. Serve hot or let cool to room temperature. In the unlikely event that you have any left, it will keep for several weeks in your refrigerator.
Serve with Honey Ham Ribs.
