What You Need to Know
Hardwood ash (primarily Quercus spp.) introduces K2CO3 and trace minerals that hydrolyze hemicellulose at lower pH (9.5-10.2) than lime (Ca(OH)2), producing distinct flavor compounds through Maillard reactions with residual phenolics.
Imparts smoky depth to masa while increasing bioavailable niacin, historically preventing pellagra in maize-dependent diets.
