Amazing! I used what I had: 2 Meyer lemons + zest, 2 backyard lemons, and one tiny Valencia orange to balance the backyard lemons. I subbed 1/4c Xylitol. And I did not have thickeners other than cornstarch so broke form and used 3 tsp of that. I used a 2 cup Pyrex measuring cup in a pot of boiling water instead of cooking the mixture directly on the flame and the result was silky smooth and delectable!
