I saw this recipe on the Kumquat Grower's website and decided to make it. My husband and I really enjoyed it. The kumquat fruit is extremely juicy and tasty, with a sweet outer peel and slightly tart inner flesh. But pureeing the peel and pulp together offers a sweet, fruity addition that produces a wonderful loaf that can be served as a side dish, quick breakfast (topped with marmalade) or as a snack. You can use any chopped nuts, but most copies of this recipe listed pecans as the preferred nut, and it's what I used and think it worked out well.
