What each ingredient does
- Alum
- Helps the pickles hold a firm, green color during the steaming process.
- Fresh grape leaves
- Provide the green color and tannins that help keep the pickles crisp.
- Vinegar
- Acidifies the brine, preserving the pickles and giving them their sharp flavor.
The step that matters
Let the pickles steam until well greened. Steaming gives the chlorophyll in the grape leaves time to pass into the pickles, so the color develops evenly. Stopping too early leaves them pale, and the alum helps the green hold.
