Sweet Potato Soup with Ginger, Leek and Apple

For one idea I’ve gone to my favorite source, the New York Times. Just today Martha Rose Shulman presented this recipe for Sweet Potato Soup With Ginger, Leek and Apple. Because I’m not a fan of leeks (too expensive to just have lying around waiting for a recipe), I’ll substitute an onion. Stronger/different flavor, I know … but that’s ok with me. Everything else is something I have on hand. My preferred kind of recipe.
