Well, because I am impatient, the recipe I picked had me soaking the peel for only 7 days, then adding the simple syrup.
I soaked the peels for about 10 days (ooh, the patience)--the vodka was truly yellow. I am thinking it MUST taste of lemon. So today, I went for the alchemy part--where it would turn that milky yellow color of limoncello.
This is so easy it's criminal. BUT. Mine didn't turn milky. What?! Why?
The only thing I can think is that the recipe used Everclear (the nice name for grain alcohol) and I used the vodka...It tastes great, so I may pass out a bottle or two this Christmas. But I also plan to go get Everclear and make another batch. Just because I want that cloudy look.
