2/3 cup nasturtium seed pods 1/4 cup salt 2 cups water 2/3 cup distilled white vinegar (5% acidity) 1 teaspoon sugar 1 bay leaf
Harvest young, light green, half-ripened seed pods while they’re still on the vines. Young pods are crisp and juicy, but tend to lose their zip and flavor as they mature (eventually, they dry out into wrinkled brown seeds and drop to the ground).
Separate the pods into individual seeds, and give them a quick rinse to remove any dirt.
The raw seeds are full of potent mustard oils that make them bitterly strong in flavor; a little too strong for my liking, so I start by mellowing them out in a simple salty brine.
In a quart jar, dissolve the salt in water. Add the nasturtium seeds, then place a zip-top bag over the rim and down into the jar to keep the seeds submerged.
