Lemons Lemons are one of my favorite flavor enhancers but you need to be careful of the white pith. If you cook the pith, it turns very bitter. Cooking the rind or pulp is fine but never use the pith or seeds. I remember discovering this disturbing fact cooking chicken piccata for the first time. I thought I could enhance the flavor by cooking lemon slices in the sauce but instead I got a bitter taste I couldn't correct with sugar.
If you love Grapefruit Sculpin from Ballast Point then you definitely have to try Watermelon Dorado. You absolutely taste the watermelon up front but it's not a sugary processed watermelon. The back end is the double IPA bitterness you like in a well designed IPA like Dorado. It's really a great pairing, likely to become a standard like Grapefruit Sculpin! I was a little skeptical, thinking it was a gimmick that wouldn't last. However, I'm still enjoying it even after my fourth one over a couple weeks time.
