What he said. It says right on the recipe and the kit should have come with the paradise. If not, get back with Forrest, I'm sure he'll square things with you.
Just did the All Grain version of this on Friday. The kit came with the paradise seeds. I was a bit confused on the lemon zest as it appeared you needed to add 2 tblsp at 15 minutes but the instructions also put lemon zest at 5 min but no amount. I just added the 2 tblsp at 15.....we'll see how it turns out....
The Jamil Show episode on wit had a recipe with zest, and the pretty much said as much zest as you can stand to gather. Seems like it takes a lot to give much flavor, but it is apparently very good.
