Combine first 4 ingredients in a large saucepan; bring to a boil. Remove from heat; add garlic, dill, and peppers to pan. Let stand 1 minute. Pour vinegar mixture over beans in a large glass bowl; cover and refrigerate 1 week, stirring occasionally.
The recipe is good, but unclear. Am I supposed to put the brine in the jar with the pickled beans after the week-long soak? The dill sprig in the picture looks fresh and pretty, can I do that in the jar and not affect the flavor?
