Pressured Cooked Citrus

I became inspired by the idea (which I learned at the FCI demonstration the other night) that pressure cooking garlic and horseradish takes away the volatile characters of these ingredients while making them both tender and delectable.  I began wondering what else would benefit from pressure cooking.  I jumped immediately to citrus fruits.  What if we could utilize an entire citrus fruit without any bitter pithy qualities?  I also wondered if we could then serve whole cooked tender citrus fruits?  Well, you can.  I started with a batch of clementines cooked in elderflower water.  I cooked them for fifteen minutes and the fruit and rind was tender and firm, like eating a yogurt.  Pretty wild.  Actually, fifteen minutes was a bit long for the clementines, the peels split a bit, though as a puree this pure essence of clementine is remarkable.  I actually turned the puree into a jelly, it seems I am on a jelly kick right now.  I have yet to figure out what the jelly is for, I am currently working on optimum gelling ratios and their applications, the clementine jelly is one of the results.
