Step 1: Sterilize your canning jars and lids by washing thoroughly with hot, soapy water, rinsing, then placing jars in a large pot, covering with water, and boiling for 10 minutes. Keep them hot until ready to fill.
Step 2: Wash cucumbers thoroughly. Trim off both ends. Cut into spears (quarters or halves lengthwise) or 1/4 to 1/2-inch slices, depending on preference for this dill pickle recipe.
Step 3: In each sterilized quart jar, place 1-2 dill heads or several sprigs of fresh dill, 2-3 cloves of peeled garlic, and 1/2 teaspoon of pickling spices (if using). Tightly pack the prepared cucumber spears or slices into each jar.
Step 4: In a large non-reactive pot, combine the white vinegar, water, pickling salt, and granulated sugar. Bring the mixture to a rolling boil over high heat, stirring until salt and sugar are completely dissolved.
Step 5: Carefully pour the hot brine over the packed cucumbers in the jars, leaving 1/2 inch of headspace. Tap jars gently and use a clean knife to release air bubbles. Add more brine if needed to maintain headspace.
Step 6: Wipe jar rims clean. Place lids on jars and screw on bands until fingertip-tight.
Step 7: For shelf-stable pickles, process jars in a boiling water canner for 15 minutes (adjust for altitude). Remove and let cool on a wire rack for 12-24 hours. For quick pickles, skip this step and refrigerate once cool.
Step 8: Store sealed jars in a cool, dark place for at least 1-2 weeks, ideally 3-4 weeks, for flavors to fully develop. Refrigerate after opening and enjoy within a few weeks.
