Pesto is one of my favorite ingredients. You can use it to make so many simple flavorful meals. This summer, I grew my first herb garden and I had a huge basal patch. I made pesto , but there was no way that I could use all of that pesto right away. So, what did I do? I froze it in individual portions, so all you do is take your fresh pesto and spoon it into a clean ice cube tray into little individual compartments. You leave a little bit of room for expansion and just fill them all up. It's that simple. And what you do is just cover it and pop it in your freezer for a while until it's nice and firm. And then what I like to do is take the pesto from the frozen state and you might need to use a little spatula or a table knife and it comes out in this nice little hard pieces and you can just pop it into your plastic bag and then I put it back in the freezer and it's ready to go. So, next time you want that fresh summery pesto flavor, just look in your freezer.
