Yes! These cardamom knots freeze great! Let the knots cool completely and then place them on a baking sheet in the freezer for 2 hours or until they are completely frozen. Then store them in a resealable Ziploc bag or airtight container for up to 2 months. Thaw them on the countertop or just warm them up directly in the microwave (1 minutes) or in an oven/toaster oven at 350°F for 10 to 15 minutes, or until warm.
