You shouldn’t use metal bowls to mix and serve salads. Instead, you should opt for wooden, glass or china bowls. For lettuce salads or mixed salads, nothing beats a wooden bowl. When you buy a wooden bowl, you can rub it with a cut clove of garlic. The wood absorbs the smell of the garlic and enhances the salad. You mustn’t wash the wooden salad bowl. Just wipe it well with kitchen paper.
