I got this over at All Reicpes. It's very similar to what I do. I add a lot more garlic and red pepper flakes, however, and I throw in some oregano and basil.
2 1/2 pounds fresh green beans
2 1/2 cups distilled white vinegar
2 cups water
1/4 cup salt
1 clove garlic, peeled
1 bunch fresh dill weed
3/4 teaspoon red pepper flakes (optional)
Sterilize 6 (1/2 pint) jars with rings and lids and keep hot. Trim green beans to 1/4 inch shorter than your jars.
In a large saucepan, stir together the vinegar, water and salt. Add garlic and bring to a rolling boil over high heat. In each jar, place 1 sprig of dill and 1/8 teaspoon of red pepper flakes. Pack green beans into the jars so they are standing on their ends.
Ladle the boiling brine into the jars, filling to within 1/4 inch of the tops. Discard garlic. Seal jars with lids and rings. Place in a hot water bath so they are covered by 1 inch of water. Simmer but do not boil for 10 minutes to process. Cool to room temperature. Test jars for a good seal by pressing on the center of the lid. It should not move. Refrigerate any jars that do not seal properly. Let pickles ferment for 2 to 3 weeks before eating.
