I developed this recipe years ago but never wrote it down. I didn’t need to — I use it so often, I know it by heart. But now it is time to share it, and I hope you enjoy it as much as I do. It makes a wonderful accent to many of the panini recipes in this book.

NotesStore in an airtight container in the refrigerator for up to 1 week. Reheat in the microwave on High power for 45 to 60 seconds before using.

I like using red onions, but you can also use sweet white onions.
