Potato Leek Soup

This creamy soup gets its luscious texture not just from heavy cream but also from the starchy potatoes. Russet (also known as Idaho) potatoes have a soft, dry white flesh that becomes velvety smooth when pureed. Tons of flavor comes from the leeks. They can often have grit between their layers and should be washed thoroughly before adding to the recipe: Brush away any dirt on the outside, then slice the white parts and transfer to a large bowl of cold water. Swirl the leeks around to release any residual dirt, then drain and repeat with more water until completely clean. Wash and use the green ends to flavor chicken or vegetable stock.
