Hey guys, I'm preparing to make my first non-ultra-budget-friendly homebrew and I decided to start off with a black cherry cider (following this recipe) which uses a 1:3 cherry juice to apple juice ratio and Safale S-04 dry ale yeast. Now unfortunately I ordered the yeast before realizing that cherries aren't really in season and after looking through literally every large supermarket chain and eshop I couldn't find any (that includes frozen and canned cherries). I'd like to stick to the recipe but I also don't just wanna sit on my bum waiting for the cherries to grow.
What fruit should be manageably easy to find and compatible with such a recipe? Thanks a lot in advance I really feel out of my depth here, hopefully this gets easier with practice.
