Orange Marmalade

1 orange
1 lemon
1 grapefruit

Can double or add whatever you'd like.  Cut into quarters, remove seeds, skin and all (or slice very thin).  Put in a blender a few pieces at a time.  Add a little bit of water.  Measure how many cups.  Then for each cup, add 3 cups of water but subtract water you already added to blender.  Cook for 20 minutes.  Refrigerate & boil again the next day for 20 minutes.  Take 3 cups and 3 cups sugar.  Cook on medium at least 1/2 hour. - Put a little in a saucer.  Freeze.  Run your finger through it.  If it separates, it's done.
