Depends on what I can get but my favorite is sour cherries, Missy
If I use sweet cherries I drastically reduce the sugar amount and add more lemon.
You probably know this- but there are two ways of making a nice cherry pie- one using the "raw" fruit as I wrote about about and how you made yesterday and then the other way where you cook the filling before you put it in the shell. It looks more like the canned-type filling after cooking but is still fresh-tasting. If you cook the filling, try using about 4 c water with the cherries, bring to a boil then turn down and simmer about 10 minutes. Pour off (but keep) all but about a cup of the liquid then dissolve the tapioca (or corn starch) in a little water then mix in- add sugar, cinnamon, whatever other stuff you like. Candied ginger would be good in a cherry pie too- then cook it a bit more to get the tapioca taste out (and thicken it) and pour into the shell.
There is also an old-fashioned Sour Cream Cherry Pie recipe that has you make a graham cracker shell (shortbread crust is good too), chill it then fill with a mixture of 3 beaten eggs, cooked cherry pie filling that includes the sugar and tapioca, spices and some sour cream. You bake this mixture without a top crust. Decadent but pretty good.
My sneaky advice is to make a pie when the DH is off doing something....then you can put whatever you want in it- LOL
