1 pound (450g) fresh jalapeno peppers, washed
2 1/2 cups (625ml) water
2 1/2 cups (625ml) vinegar (I used white distilled vinegar)
3 T. sugar
3 T. coarse salt, such as kosher
2 bay leaves
2 T. whole coriander seeds
3 cloves garlic, peeled
2 T. black peppercorns

Stab each pepper three times with a sharp paring knife and place them in a large glass preserving jar. In a non-reactive saucepan, bring the other ingredients to a boil, then reduce the heat and simmer for five minutes. Remove from heat and pour the brine over the peppers. Place the lid on the jar and let cool. Once cool, refrigerate for at least a week before using, if possible. Serve whole, with Mexican dishes, or remove the seeds then chop and use to season any recipe that is improved by a little bit of sweet heat.
