4. Triple-cherry filling
You make triple-cherry filling with three kinds of cherry – preserved Morello cherries, Bing cherries and dried tart cherries. You can start by mixing your Morello cherries (with their syrup) and tart cherries with cinnamon, nutmeg and ¼ cup of cornstarch.
It needs to cook over low heat for a few minutes. Add the Bing cherries and cook the mixture for 5 more minutes. When the mixture thickens, your filling is ready for the pie.
