What You Need to Know
The technique relies on controlled heat (55–65 °C) and vacuum sealing to promote mass transfer of volatile aromatic molecules into the protein. At these moderate temperatures, Maillard reactions are minimal, preserving delicate flavors while allowing extended contact time for diffusion. The result is a tender, moist protein enriched with subtle, complex aromatics without overcooking.
