My new favorite use for leftover parmesan rinds is to make this quick parmesan powder which extends the parmesan flavor and can be used in dozens of delicious ways!
Ingredients
3-4Parmesan Rinds, leftover
Instructions
For each parmesan rind, use a paring knife to trim off any wax on the very exterior edge of the cheese. Try to keep as much cheese as possible. Cut the leftover rind in to 1 or 2 inch chunks.
Place rind chunks on a microwave safe plate and microwave on high for 2 minutes. Watch carefully. Depending on thickness, they might only need 90 seconds or a few extra seconds. Cheese pieces will puff slightly and then start to brown a bit. Make sure not to burn them.
When you remove the parmesan pieces, let them cool completely and then mash into a powder using a mortar and pestle or place them in a bag and smash them.
Store parmesan powder in an airtight container in the fridge for a few weeks.
