When a vegetable soup contains whole or chopped vegetables, additional garnishing usually isn’t needed, because the soup will look striking on its own. Pureed soups, though, have one color and the same consistency and usually need some kind of garnish. The obvious garnish for most purees is a piece of the vegetable that went into the soup, placed on top of each serving in the middle of the bowl. If you’re making an asparagus soup, for instance, save some of the tips, cook them in boiling salted water, and place one or more in the center of the bowls.
