Mustard Caviar

This homemade mustard caviar is a sophisticated addition to any pantry, offering a delightful pop of texture and a bright, tangy finish. By gently simmering brown and yellow mustard seeds in a balanced mixture of rice vinegar and apple cider vinegar, the seeds soften while retaining their distinct shape. The result is a versatile condiment that mimics the luxurious mouthfeel of traditionally cured roe, making it a wonderful conversation starter for your next dinner party.

As a low-sugar recipe, this preparation focuses on the sharp, aromatic qualities of the mustard rather than excessive sweetness. It is particularly effective when served alongside rich proteins such as grilled steak or roasted salmon, providing a clean acidity that cuts through savoury fats. For a simple vegetarian option, try spooning a small amount over devilled eggs or thick slices of vintage cheddar on a crusty baguette.

Ingredients for Mustard Caviar

  • 120ml rice vinegar

  • 60ml brown mustard seeds

  • 60ml yellow mustard seeds

  • 60ml apple cider vinegar

  • 60ml sugar

  • 1/2 tablespoons kosher salt

How to make Mustard Caviar

In a small saucepan, bring 120ml rice vinegar, 60ml brown mustard seeds, 60ml yellow mustard seeds, 60ml apple cider vinegar, 60ml sugar, 1/2 tablespoons kosher salt, and 180ml water to a boil over medium-high heat. Reduce heat to low and simmer, stirring often and adding water by tablespoonfuls if mixture is too dry, until mustard seeds are still firm and intact but pop like caviar when bitten into, 45-50 minutes. Remove saucepan from heat and let mustard mixture cool completely. Transfer to an airtight container and refrigerate. Keep chilled in the fridge for up to 2 weeks.
