Home cooks and off-grid dwellers struggle to preserve fresh herbs without refrigeration

People without reliable refrigeration or freezer access—including those in developing regions, off-grid homesteads, or experiencing food storage constraints—cannot keep fresh scallions and herbs edible beyond a few days, forcing them to waste produce or eat spoiled food. Current preservation methods (drying, pickling, salting) either destroy the fresh texture/flavor or require specific ingredients and equipment they don't have access to.
