What You Need to Know
The grinding action disrupts parenchyma cells in herbs (e.g., cilantro, parsley) releasing pectin and phospholipid-rich organelle membranes. Concurrent crushing of garlic alliinase converts alliin to allicin, which complexes with olive oil polyphenols.
Creates stable herb-infused oil emulsions without modern emulsifiers, essential for texture and flavor dispersion in condiments like chermoula.
