Pickled Red Onions
1 small white or sweet yellow onion
1 small red onion
1/2 cup cider vinegar
1/2 cup distilled white vinegar
1/2 cup granulated sugar
2 tsp. celery seed
1 tsp. crushed red pepper flakes
Cut onions into thin slices and place in a non-reactive (glass) shallow dish. In a bowl whisk together vinegars, sugar, 1 tablespoon sea salt flakes, celery seed, and red pepper flakes until sugar and salt are dissolved. Pour vinegar mixture over onions; stir to evenly coat. Cover and set aside at room temperature for 2 to 3 hours, stirring occasionally. Top your summer hot dogs with this and enjoy!
