This is the second year that I've made maraschino cherries. Last year I heated some Luxardo Maraschino just to boiling, turned off the heat, and added the cherries (sour cherries). I gently stirred the cherries and then bottled the results, keeping them in the fridge. The cherries were delicious. After about a month the liqueur had taken on a beautiful red tinge. After 9 months or so the cherries had shrunk and darkened considerably, but were still tasty. At the one year mark the cherries were rather hard, but still decent with a slightly muted but still present cherry flavor. This year I took the liqueur from last year, heated to boiling again, and poached a new batch. They won't be ready for at least another week or so, but I snuck one and it was pretty good!
