This was our favorite recipe test of the soup batch. Inspired by a sweet potato and apple purée I make every year for Thanksgiving, the soup also has savory overtones. For a spectacular finish, garnish...
White beans and pesto or pistou (pesto without the pine nuts) always make a nice marriage. Thin the pistou with a little extra olive oil so that you can drizzle it over the rich-tasting purée.
This simple, fragrant soup is delicious as thick vegetable soup, not puréed. It becomes a different soup altogether when you purée it, and I like both versions equally.
