Description
Anaerobic fermentation of banana peel ash creates organic acids for souring soups.
Technical
Carbonized banana peels (kilikili) undergo microbial conversion of residual carbohydrates into acetic and lactic acids via heterofermentative pathways, while potassium carbonate from the ash buffers pH.
Culinary Significance
Provides tangy depth to bitter leaf soup (ofe onugbu) and replaces scarce citrus in dry seasons.
