Pickled Strawberry Jam

Directions

1. In a bowl, whisk the sugar, pectin, and salt to combine. If a seedless jam is desired, purée the berries in a blender and strain through a fine-meshed sieve. Otherwise, leave them whole, or cut large ones into quarters.
2. In a medium saucepan, combine the sherry vinegar, rice wine vinegar, coriander, and cardamom. Bring to a boil over medium heat, and immediately remove from heat. Remove and discard the coriander seeds and cardamom.
3. Return the saucepan to medium heat and add the sugar mixture, stirring with a wooden spoon until blended; it will be dry at first. Add the strawberries or strawberry purée, and continue to stir, crushing the berries with the spoon, until the mixture is liquefied and comes to a boil. Continue to boil, stirring constantly, until thickened, about 3 minutes.
4. Pour the jam into a heat-proof bowl and let cool completely. Store it, covered, in the refrigerator. The jam can also be frozen for up to six months.
