2. Put the nasturtium seedpods in a half-pint glass jar and pour the boiling brine over them.
3. Cover and let them soak at room temperature for 3 days.
4. Drain the nasturtium seedpods in a fine sieve and return them to the jar.
5. Bring the vinegar, sugar, bay leaves, and thyme to a boil in a small (1-quart) saucepan.
6. Pour the boiling vinegar mixture over the seedpods and let cool.
