FAQ

Can I use only one type of berry instead of mixed?

Yes, you can use any single berry type. Adjust sugar slightly based on the natural sweetness of your chosen berry, with strawberries needing less and cranberries needing more.

What if my syrup is too thick or too thin?

If too thick, stir in a tablespoon of hot water. If too thin, mix another teaspoon of cornstarch with cold water and boil for another minute.

How long will this syrup keep in the refrigerator?

Properly stored in a sealed container, the syrup will keep for up to 2 weeks. The natural fruit sugars and acidity help preserve it safely.
