I make all kinds of pesto, and love to play around with the flavors. Basically what I do is make a standard pesto recipe.....but add or substitute. To the basic recipe you can certainly add fresh garlic, however much you want. I also add fresh lemon juice and/or zest. Sometimes I make parsley, cilantro, or arugula pesto using the same measurements for regular. I favor adding less oil than called for. I use all sorts of nuts, pecans, pistachios, macadamia, almonds. I have even added Serrano peppers, jalapeño, or roasted sweet Italian to cilantro, or parsley pesto. Just play with it. You will soon get your favorites. Taste as you go, you can always add more flavor. Oh, and I play around with different oils too, walnut, almond, pistachio, and so on. I freeze my pesto in ice cube trays, then put the cubes in Food Saver bags. Be sure to label your flavors on the bag. I forgot to do that one year and had a hard time pulling the right pesto for the recipe I was making.
