When preparing onion grass for preservation via quick freezing, what should be done with the minced material before transferring it to a sealed freezer bag?
Lay the minced grass thinly on a parchment-lined baking sheet until frozen solid.
The technique for flash-freezing minced onion grass is designed to preserve its texture and volatile flavors while preventing the individual pieces from agglomerating into a solid block inside the storage bag. To achieve this, the finely minced grass blades (and optional bulbs) must first be spread out thinly and evenly across a baking sheet that has been lined with parchment paper. This setup allows for rapid, uniform freezing of each piece individually until they are completely frozen solid. Only after this flash-freezing process is complete should the frozen pieces be transferred into a sealed freezer bag for long-term storage, ensuring the flavor compounds remain accessible for future cooking.
