These sweet treats are used as a delightful layer in our Black Forest Cake Shake.
Combine sugar and cherry juice in a small saucepan. Add salt and bring to a boil, stirring to dissolve the sugar. Simmer 1 minute. Add cherries and simmer 1 minute. Remove from heat and stir in Kirsch. Let cool completely before storing in an airtight container. Chill for up to 1 week.
We used jarred sour cherries for this recipe, but fresh sour cherries would work just as well. Remove their pits first, then simmer briefly in a simple syrup (equal parts water and sugar) before stirring in the cherry liquor.
