Pepper Mangoes

Ingredients

Directions

Prepare the bell peppers by scalding them if you want to remove the seeds.
Fill the peppers with chopped cabbage, mustard seeds, horseradish, celery seeds, and allspice.
Tie the filled peppers with wide strips of muslin.
Place the tied peppers in a jar and cover them with cold vinegar.
Put cross sticks over the top of the pickles to keep them submerged in the vinegar.
Store the pickles in the vinegar to keep them fresh.
