With adjustment for cooking only 1 hour (even at high elevation, 7200 ft.), this came out just fine. Doesn't taste a lot like watermelon - more like citrus "marmelade"; but that could be because the watermelon I used wasn't that good to begin with - which is why I used it! As recipe is written, it only made a little more than 3 half-pints. I made the first batch with 2 lemons, 1 orange. I'm now cooking a 2nd batch, which I doubled, using 1 grapefruit, 2 oranges and 2 lemons. I ran all the citrus through the food processor using the grating attachment. Seeds, membranes mostly stayed above the grater; but additional seeds and membranes can be easily picked out of the pot while cooking.

This is a good recipe for a different kind of preserve. It is beautiful to look at. I made a few changes though, and would make a few more the next time I make it. First, I used one orange and one lemon. Second, I only simmered for one hour and it was perfect. It set up beautifully. It has a good flavor but it is really more of a marmalade. The other thing is that when I was through simmering, the lemon and orange were still pretty big so I took my kitchen shears and cut through the mixture until the peel was nice size; I will do this before the simmering next time. Other than that, if you are looking for a "different" recipe, then you should definitely try this one!

I think this recipe is wrong - it seems as though the mixture should boil for only 1 hour. I followed the directions to a T and after 2 hours the mixture was very burned. I think with only 1 hour of boil time it would be perfect. May try again!
