4 pounds haricots verts or 4 1/2 lbs. regular green beans
14 sprigs fresh dill, each 4 in. long
14 sprigs fresh tarragon, each 4 in. long
7 garlic cloves, peeled
about 1 1/4 tsp. black peppercorns
1 qt. (32 oz.) white-wine vinegar (5 percent acidity)
2 tablespoons plus 1 tsp. salt (optional)
1. Follow directions in "Canning ABCs: Get Ready" (below), using 7 regular or wide mouthed pint jars, rings, and lids.
2. Trim stem ends from beans, keeping tips intact, so beans are 3 1/2 to 4 in. long.
3. Pack jars: Holding each jar on its side, insert 2 sprigs dill, 2 sprigs tarragon, and a garlic clove. Fill snugly with beans, tips down. Sprinkle about 12 peppercorns into each jar.
4. In a large saucepan, bring vinegar, 1 qt. water, and salt (if using) to a boil over high heat. Ladle liquid over beans to within 1/2 in. of rims; discard any extra liquid. Wipe rims and seal with lids and rings as directed.
5. Process as directed in "Canning ABCs: Process Jars," but keep water at 180° to 185°, checking with a thermometer, for 30 minutes (add 5 minutes for every 3,000 ft. in altitude above sea level). Cool, check seals, and store as directed (up to 1 year).
