Can I make this sauce ahead of time?
Yes, prepare it up to 5 days in advance and store in an airtight container in the refrigerator. Reheat gently over low heat or serve chilled.
What can I substitute for peach and apricot preserves?
Use all peach, all apricot, or swap in pineapple preserves. Jam works as a substitute but will yield a slightly thicker sauce.
How thick should the finished sauce be?
The sauce should coat the back of a spoon. If too thin, simmer longer; if too thick, whisk in a tablespoon of water at a time.
Is this sauce gluten-free?
Check your preserves and soy sauce labels, as some brands contain gluten. Most light corn syrup and other base ingredients are naturally gluten-free.
