Ingredients:
- 3 lbs English cucumbers, sliced into 1/8-inch rounds
- 2 medium white onions, thinly sliced
- 3 tbsp kosher salt
- 2 cups apple cider vinegar
- 1 cup granulated sugar
- 1 tsp salt
- 1 tsp mustard seeds
- 1/2 tsp celery seeds
- 1/2 tsp turmeric powder
- 1/4 tsp red pepper flakes
Instructions:
- Combine the sliced cucumbers and onions in a large bowl, sprinkle the kosher salt evenly over the vegetables, and toss to coat.
- Allow the mixture to sit for 2 to 3 hours to draw out excess water, then rinse the vegetables thoroughly under cold water and shake well in a colander until moisture drops.
- In a stainless steel saucepan, combine the apple cider vinegar, sugar, salt, mustard seeds, celery seeds, and turmeric.
- Bring the mixture to a gentle boil over medium heat, stirring occasionally until the sugar crystals have completely dissolved.
- Remove the brine from the heat immediately to avoid over-reducing.
- Tightly pack the rinsed cucumbers and onions into clean wide-mouth glass jars, pressing down firmly to eliminate air pockets.
- Pour the hot brine over the vegetables, ensuring they are completely submerged.
- Seal the jars and refrigerate for 24 hours to allow the flavors to infuse.
