Pesto is the simplest sauce in the world. All you need are fresh herbs, a little salt, and oil. Basil is traditional but you can use any seasonal herb. You can even use a mortar and pestle or lots of knife work instead of a blender or food processor.
And yet, there are secrets to making a bold, balanced pesto.
First, don't skimp on the fat. Oil creates a smooth texture while holding the color and flavor of the herbs. Use high quality oil because the flavor comes through the final product. Oil also tones down the strong flavor of the greens. To prevent freezer burn, top a container of pesto with a layer of oil before freezing.
Always add a little acid. A splash of lemon juice or vinegar balances the richness of the oil and preserves the color.
Experiment seasonally. Basil pesto is a classic in the summer but don't leave pesto behind in the other seasons. Play with spinach and kale in the fall and microgreens in the winter and spring.
