FAQ

Can I make the balsamic reduction ahead of time?

Yes, it keeps refrigerated for up to one week. Gently rewarm before using or use at room temperature for easier drizzling.

What if I don't have aged balsamic vinegar?

Regular balsamic works but may need longer cooking time to achieve the same thickness and concentrated flavor as aged varieties.

How long will assembled sandwiches keep?

Best eaten immediately as bread becomes soggy quickly. Maximum 30 minutes before quality deteriorates significantly.
