Steam-Jacketed Kettle

A steam-jacketed kettle surrounds the cooking vessel with steam, transferring heat evenly through the walls for efficient high-volume liquid and semi-liquid food production.

Best Uses

Soups, stocks, sauces, stews, gravies, custards, pasta sauces, braising liquids, and other large-batch preparations.

What to Look For

• Capacity suited to normal batch size.
• Accurate temperature or steam-pressure control.
• A reliable tilting or draw-off system.
• Accessible interior surfaces for cleaning.

Correct Use

Allow sufficient headspace, stir products according to viscosity, control heat during reduction, and use the draw-off or tilt mechanism carefully when transferring hot food.

Common Mistakes

• Overfilling the kettle.
• Reducing thick sauces at excessive heat without agitation.
• Ignoring residue around valves and outlets during cleaning.

Chef’s Notes

Because heat surrounds much of the vessel, steam kettles are efficient and forgiving for large batches, especially when compared with heating an oversized stockpot from below.
