Q: What is the etiquette concerning how to eat a meal? For example, my husband eats his entire serving of vegetables, then his entire serving of potatoes, then his entire serving of meat, rather than sampling from each at random.
A: When foods are served together on one plate, and not as courses, it is customary to eat them together – a sampling from each, at random, as you described. The cook has tried to select foods that compliment one another, with the intention of them being enjoyed together. It is not impolite to eat each food separately, however, so if this is the way your husband prefers to eat, there is nothing wrong with it.
