You can substitute a portion of the strawberries with other fruits to make different combinations. I made a second batch substituting two cups of rhubarb for two cups of the strawberries and it turned out fantastic!
Adapted from Back to Basics
Note: I only test the recipes on my site with the listed ingredients and measurements. If you would like to try a substitution, you are welcome to share what you used and how it turned out in the comments below. Thanks!
