Rinse okra. Optionally, trim stem ends. Wash 7 quart canning jars. Place a clove of garlic and two halves of pepper in each jar. Pack jars firmly with okra.
Combine salt, water, vinegar, and dill seed in a large pot. Bring to boil. Pour pickling solution over okra in jars, leaving 1/2" head space. Manipulate out air bubbles in okra, clean jar rims, and install lids. Process for 15 minutes in hot water bath.
