In Texas, we consider dill a cool-weather annual. Plant this herb in the fall, typically mid- to late October, and you can begin harvesting leaves around eight weeks later. It prefers temperatures between 40º and 78º F, but you’ll find mature plants are frost-tolerant.
Our dill harvest is usually over long before we have much to pickle. To preserve dill for the cucumber or okra harvest yet to come, cut fresh dill fronds and bloom heads into segments 2 to 3 inches in length. Fill a gallon-sized glass jar with the dill segments and completely cover with white vinegar (or your pickling vinegar of choice). If the jar has a metal lid, be certain to cover the jar first with a double layer of plastic wrap before screwing on the metal lid. This will prevent corrosion. Place the jar in a cool, dark place until you’re ready to start pickling your harvest. By then, your pickling vinegar will be well flavored and can be used as directed in a favorite recipe. I found this information in a Texas Gardener magazine article.
One of our family’s favorite “real dills” is pickled okra. To use the preserved dill and vinegar as described above, use this recipe for small batches of pickled vegetables. We also like to add sliced jalapenos.
Basic Pickling Liquid
2 cups dill infused cider vinegar
1 cup water
1/4 cup granulated sugar
4 whole cloves garlic
3 tablespoons coarse kosher salt
1/4 cup equal parts mustard seed, black peppercorns, coriander seed, dill seed and lightly crushed red pepper (approx. 2-1/2 teaspoons each)
Combine all ingredients in a non-reactive saucepan and simmer gently for 15 minutes. Pour hot liquid over clean, prepared vegetables, add some of the reserved dill leaves and stems from the dill vinegar, and refrigerate until well flavored.
