Delicious soup. Simple ingredients, but with a complex result - the leeks give it a lot of flavor, and the brie a subtle bit. I subbed celery for the apples (personal preference on sweetness with savory), added pepper, used liquid milk (we prefer the taste to evaporated) and only pureed some of the potatoes, since we like our soups chunkier. It was very tasty. I think this is set for an appetizer size portion of soup, since we got three entree size portions out of it.
