- Hot distilled vinegar
- Adds sharp acidity that softens the lemons and carries the spice flavors.
- Mustard seed
- Adds a sharp, pungent bite as its flavor is drawn out.
- Horseradish
- Adds a pungent, sharp heat that deepens the pickle's flavor.
- Cayenne
- Adds direct heat that gives the pickle its warmth.
