When grinding horseradish, a colloid mill should ideally be enclosed or fitted with proper ventilation, since the shearing process releases pungent volatile compounds that can be irritating in an open room, and cooling helps control the heat-sensitive reaction responsible for horseradish’s characteristic sharpness. With correct gap settings, the mill produces a smooth, evenly textured horseradish paste ready for blending with vinegar or cream-based products.
