What You Need to Know
Steaming at 100 °C limits water‑soluble vitamin leaching by keeping the temperature at the boiling point of water, while pressure cooking raises the boiling point to 121 °C, allowing faster cooking with less water. Sous‑vide cooking at 55–85 °C uses a sealed environment that prevents evaporation, and recirculating steam ovens condense and reuse moisture, all of which reduce overall water use.
