I love this recipe from Ina Garten. This is my second year making it with oranges and lemons from our trees. It is so easy, and the flavor is outstanding. I love that the entire orange and lemon is used, no waste, even the white pith is used. The marmalade is not as bitter as one might think, perfect ratio to the sweet. It sets perfectly without the use of pectin.http://www.foodnetwork.com/recipes/ina-garten/annas-orange-marmalade-recipe
