Description
Low-temperature smoking with dried hay imparts grassy, earthy flavors through controlled pyrolysis of plant compounds.
Technical
Thermal decomposition of cellulose and lignin in hay produces guaiacol, syringol, and other phenolic compounds that adsorb onto food surfaces. The process occurs at temperatures below 100°C to prevent burning while allowing volatile organic compounds to permeate.
Culinary Significance
Creates a delicate smoke flavor profile distinct from wood smoking, particularly suited for dairy products, seafood, and vegetables in Nordic cuisine.
