Yes, LB--but, unfortunately, the flavor of the peel will be gone as well. Actually, it begins to dissipate several hours after falling from the tree. I've studied it, as I have made Limoncello for the last several years. I would imagine youo would get a better rind with freeze dried; but not so sure. Try your luck at it Sailor--I'm sure it will be wonderful!
I made a 2 gallon batch, and used about 2 tblsp. ginger--it does smell great. The key lime seasoning had some pepper and other herbs as well, so I'm not certain of all the ingredients working together. Like the idea of candied rind--wish I had thought of it while the lemons were still in bloom here.
