Making a big batch of homemade pesto and pouring it into an ice cube tray to freeze is super handy! Once the sauce is frozen, remove the cubes from the tray and store them in a ziploc bag in your freezer. Frozen pesto can be a life saver as well as a huge improvement to many dishes. From sandwiches to pasta or chicken dishes, simply grab a cube of pesto, melt into your dish and voila, you have added a fancy homemade touch to your meal in no time.
