Which large perforated bowl is used to drain vegetables and salad greens?

The large perforated bowl designed specifically for draining vegetables and salad greens is known as a colander. This kitchen tool features a wide bowl with many holes, allowing water to escape while retaining the food inside. It's particularly useful for rinsing leafy greens or cooked vegetables, ensuring that excess water is effectively removed before further preparation or serving.

In comparison, a china cap is a type of strainer or sieve with a fine mesh, primarily used for straining stocks or sauces rather than draining larger vegetables or greens. A bain marie is not a draining tool at all; it’s a cooking method that uses hot water to gently cook or keep food warm in a container placed in another container. Lastly, while a strainer serves a similar function as a colander, it typically has a finer mesh and is more suited for smaller particles like pasta or dusting flour, rather than the bulk drainage of larger items like salad greens or vegetables. Thus, the colander is the most appropriate tool for this particular task.
