Basil is one of my favorite herbs. It has incredibly rich and spicy flavor and it can be used in many recipes. I grow it in my garden every year and at the end of the season I try to preserve as much of it as I can. Last year I found out that the best way to preserve it is by freezing it together with the ever flavorful parmesan cheese. This way the two absorb each other's flavor and you end up with a tasty ingredients for your culinary creation.
Pick the bigger and medium leaves that look healthy. This way the smaller leaves that are developing will have a chance to grow bigger. Wash them and prepare your parmesan - grate it if you have to. I buy my raw in Trader Joe's.
I use big yogurt cup for storage but you can use any other plastic container that will fit all your ingredients. Start with a layer of parmesan.
Then chop the basil leaves up into smaller pieces and place layer on top of the parmesan.
Repeat the layers till you use up all your basil...or run out of space.
Last, close up the cup and write the description. Don't forget the date, this will last in your freezer for about 6 months. I was using it longer and it was still fine.
You can use it as Pizza topping, or as an ingredient in your pasta sauce.
