¼cuppickling salt or kosher salt
1cupprepared horseradish*feel free to adjust to taste
1½cupslight brown sugaror granulated sugar
1tspcelery seed
2tbspmustard seed
cold white vinegarto cover
Instructions
Place chopped cucumbers and 1/4 cup salt in a colander over a bowl and toss to combine. Cover, refrigerate and allow to drain overnight. You will have a large amount of water in the bowl the next morning.
Drain and rinse cucumbers in ice cold water, filling the bowl. Drain well; this helps to remove the excess salt.
Chop peppers and onions. Add to cucumbers.
In a separate bowl, combine sugar, horseradish, celery seed, and mustard seed. Let sit at room temperature until sugar dissolves. Add to cucumber mixture and then add enough vinegar to cover.
Bottle in your favorite jars and store in the refrigerator for up to 6 weeks, freeze, or give as gifts to friends.
Notes
Salting and draining the cucumbers is the most important step. Skip the old-school sack method and set the salted cucumbers in a colander over a large bowl, cover it, and refrigerate. By morning, you’ll be amazed at how much liquid has drained off! Rinsing them afterward removes extra salt and keeps them crisp.
When chopping your veggies, aim for small, uniform pieces. This ensures you get a satisfying balance of tangy sweetness and crunch in every spoonful. I like my relish a little chunky, so I dice the cucumbers, peppers, and onions into about ⅛ – ¼ inch pieces.
Let the relish rest in the fridge before serving. Technically, you can use it right away, but I recommend letting it sit in the refrigerator for at least 24 hours before serving. This gives the fresh veggies time to marinate gently in all that tangy-sweet goodness.
