Olia Hercules' Watermelon Rind Jam

August 12, 2015

Author Notes: Yes, this is about making clever use of waste, as we're trying to do more and more these days. But it's also about seeing a new side of a fruit that provides a pretty straightforward experience most of the time. And not only does it have more depth and personality than you ever thought watermelon could, it's also the backbone to a better and lighter marmalade than most. Note: The limes will make this more fragrant, acidic, and bitter, but you can leave them out if you're looking for something more straightforward and sweet. Slightly adapted from Mamushka (Mitchell Beazley, 2015).Genius Recipes
