Method
Wash the peppers and parsley well. Remove the pepper tops, scoop out the seeds, then pound the garlic with a little salt and mix it with coarsely chopped parsley to make the filling.
Stuff the peppers and stand them upright in a clean jar. Cover the surface with a few grape leaves.
Pour over salted water strong enough to float an egg, then leave the jar in the sun. Start tasting after about a week; if you are not using grape leaves, a little sugar may be added the way the book notes.
Notes
The original page gives the classic floating-egg test for brine strength rather than an exact salt ratio.
