Notes
For best results, cut fruit into uniform pieces for even cooking.
Let cool at least 15 minutes before serving to let the filling set.
Cover and refrigerate leftovers for 3-4 days.
Reheat individual portions in the microwave for 30-45 seconds.
Frozen rhubarb can be used without thawing; if using frozen strawberries, thaw and drain first.
