Before we went on our trip, Eric's Dad sent us home with a big pile of fresh herbs from his garden. Knowing that we wouldn't have time to use or dry them before we left, I quickly Googled how to freeze herbs and found the idea of preserving them in olive oil over at The Kitchn.
I chopped the herbs and placed about 2 tsp. of each one in an ice cube tray. I poured enough oil over to cover the herbs and froze them for a few hours. Once they were solid, I popped them out of the ice cube trays and into labelled freezer bags.
