Step 1: Prepare your canning jars and lids by sterilizing them. Wash jars thoroughly with hot soapy water, rinse, and then place them in a large pot. Cover with water and boil for 10 minutes. Keep jars in hot water until ready to fill. Place lids and rings in a separate small saucepan with hot (not boiling) water to soften the sealing compound.
Step 2: Wash cucumbers thoroughly. Trim off both ends of each cucumber. If desired, cut cucumbers into spears, slices, or leave them whole if small enough to fit in your jars.
Step 3: To each sterilized pint jar, add 2 cloves of garlic, 1 sprig or head of fresh dill, 1/2 teaspoon mustard seeds, and 1/2 teaspoon black peppercorns. Add red pepper flakes now if desired.
Step 4: Tightly pack the cucumbers into the prepared jars. Try to get them as snug as possible without bruising them.
Step 5: In a large pot, combine white vinegar, water, and pickling salt. Bring the mixture to a rolling boil over high heat, stirring to dissolve the salt. This is your pickling brine for the dill pickle recipe.
Step 6: Carefully pour the hot brine over the cucumbers in each jar, leaving 1/2 inch of headspace (space between the liquid and the rim of the jar). Tap the jars gently to release any trapped air bubbles. Use a non-metallic utensil to push down any cucumbers that might be floating.
Step 7: Wipe the rims of the jars with a clean, damp cloth. Center a hot lid on each jar and screw on the band until fingertip tight (snug but not overly tight).
Step 8: Place the filled jars into your boiling water canner, ensuring they are fully submerged by at least 1 inch of water. Bring the water back to a full rolling boil and process for 10 minutes (for pint jars). Adjust processing time for your altitude if necessary.
Step 9: Carefully remove the jars from the canner using a jar lifter and place them on a clean towel or cooling rack, ensuring they are not touching each other. Let them cool undisturbed for 12-24 hours. You should hear the lids 'ping' as they seal.
Step 10: Check seals by pressing the center of each lid. If the lid does not flex, it is sealed. Store sealed jars in a cool, dark place for at least 3-4 weeks (preferably 6 weeks) before opening to allow the flavors to develop fully. Unsealed jars should be refrigerated and consumed within a few weeks. Enjoy your homemade dill pickle recipe!
