What Are Pickled Mustard Seeds?
Pickled mustard seeds, also referred to as mustard caviar, are a flavorful condiment made by soaking whole mustard seeds in a vinegar brine. The dry seeds take on the bold vinegar flavor to add an element of acidic flavor to anything it’s added to.
Ingredients
Here are the key ingredients to make this pickled mustard seed recipe. For the full list of ingredients, reference the recipe card below.
- Mustard Seeds
- White Wine Vinegar
- Brown Sugar
- Kosher Salt
For pickling, a 5-6% acetic acid vinegar is recommended as it provides enough tartness without overpowering the natural flavors.
How To Make
The pickling process is simple and quick. Here’s a brief overview of the key steps. The full list of instructions is in the recipe card below:
- Blanching – This is an optional step to remove the excess bitterness.
- Making The Condiment – Add all the ingredients to a saucepan and simmer away!
Types of Seeds
There are 3 different types to consider using. All will work well, however will provide different final results. You can also mix and match.
Yellow Mustard Seeds
Yellow mustard seeds, also known as white mustard seeds, are tiny, round seeds of the plant. Yellow seeds have a mild, slightly spicy flavor. Despite their small size, they pack a flavorful punch and add a unique touch to many dishes.
They are the most commonly used types of mustard seeds. The names “yellow” and “white” refer to the color of the seeds when they are dry.
Brown Mustard Seeds
Brown mustard seeds are small, round seeds of the plant that have a deep, nutty flavor with a rich, dark brown color.
They have a slightly stronger flavor compared to yellow or white varietals, which makes for a more robust and spicy pickled mustard seeds recipe.
Black Mustard Seeds
Black mustard seeds are the small round seeds of the plant. They have a strong and nutty flavor and aroma. The black varietal is harder to find than yellow or brown. Additional details can be read on wikipedia.
Blanching The Seeds
Mustard seeds can be bitter, particularly the brown and black seeds. To remove some of the bitterness, blanch the seeds in boiling water a few times before proceeding with the recipe.
We tend to omit this step when utilizing yellow seeds, as we don’t find them overly bitter, but it’s up to you.
Variations
Sweet – To sweeten up the final product, increase the sugar by 1 tablespoon. We do recommend tasting the initial vinegar brine first to get a baseline flavor.
Spicy – If you love spice add in some red pepper flakes, to taste.
Vinegar – Use any vinegar you prefer. We prefer white wine vinegar, but apple cider vinegar or red wine vinegar also work.

Storage
Store the pickled seeds in an airtight glass container, away from direct sunlight and heat to prevent spoilage. Ideally, place the jar in a cool, dark pantry or cupboard for optimal preservation.

Tips
- Start by adding a small amount of pickled mustard seeds to your dishes, as their tangy and spicy flavors can be quite intense.
- Pair pickled mustard seeds with creamy ingredients, like goat cheese or avocado, to balance their bold flavor. Think avocado toast!
