Do you ever wonder what was going through the mind of the person who decided to make a sauce from fresh basil leaves? I guess I can see someone saying “you know? we keep tearing up these leaves and adding it to our pasta … and we always use garlic and Parmesan cheese … a good drizzle of olive oil never hurt”. But then … “Oh! and hey! let’s throw in some nuts!”
I still don’t get it. I do hope that one day I will be watching Food Network or looking through Cooking Light Magazine and that secret will be revealed to me. (Yes I did google it, but my first 10 attempts just kept telling me what goes into pesto, not why.)
I did learn that “pesto” is a shortened form of the Italian word “pestato” which means to crush or pound. It is derived from the Latin word “pestle” which leads us to a mortar and pestle which leads me to thoughts of guacamole! Huh. Two of my favorite green condiments.
Meanwhile … I am perfectly happy that someone else had that lightbulb moment: “PINE NUTS! That’s what this sauce needs!”
Although traditional pesto is made from basic ingredients (basil, olive oil, garlic, Parmesan cheese and pine nuts) plus a little salt and pepper, many variations have become popular. Parsley, cilantro, spinach, kale, arugula and many other “greens” have been substituted for or combined with the basil. The pine nuts have been replaced with walnuts, cashews, almonds, pepitas, and even pistachios. Some add jalapeno, asparagus or sun-dried tomatoes. Just type “pesto” in the search bar on Pinterest, and the possibilities will be revealed to you.
This pesto recipe is my favorite. It uses a mixture of spinach and basil for a milder flavor and adds in some lemon juice and zest. It makes about a cup and a half of pesto (12 oz).
Some people use pesto all the time and have absolutely no trouble using this much pesto before it starts to turn brown. Throwing away a half a jar of pesto (or anything else for that matter) really frustrates me. To solve this problem, I freeze the pesto in manageable portions (about two tablespoons). Want to add some to a sandwich? Take one out. Making lasagna or a pasta salad? Grab two or three. Need to boost the flavor of a soup? The solution is in the freezer. Discs will defrost in an hour or less and are always available.
Lay parchment paper or plastic wrap on a freezer-friendly baking sheet. Scoop 2 tablespoons of pesto on the parchment (like making cookies) and place baking sheet in the freezer for 2-3 hours. When discs are frozen, wrap each one in plastic wrap and place the discs in a resealable bag and return to the freezer.
How do I use these little packets of goodness?
- instead of traditional pizza sauce (spread a thin layer of it on the crust)
- on chicken breasts or vegetables for grilling
- as a sauce for pasta or pasta salad (incorporate a little of the leftover pasta water to give it a creamier consistency)
- stirred into the cheese mixture in lasagna (e.g. Lasagna Rollups) or cavatelli
- spread on the bread of a Panini or breakfast sandwich
- drizzled on fresh tomatoes and fresh mozzarella
- mixed with cheese to make these easy Avocado-Stuffed Tomatoes
My next experiment with pesto? Chilled Basil Tomato Red Pepper Soup
I’ll make sure to let you know how that one turns out. Or, if you beat me to it, let me know if it’s a keeper!
