Instructions
Load the bowl: Add pistachios, basil, Parmesan, garlic, lemon zest, and salt to a food-processor bowl (or a large mortar).
Make the paste: Mortar: pound to a coarse paste, then work in the olive oil until glossy. Processor: run on low and drizzle in the olive oil until the pesto turns smooth, pausing once to scrape the sides.
Notes
Pistachios — Start with raw, unsalted kernels. For a deeper, toasted flavor, bake 8–10 min at 175 °C / 350 °F until fragrant, then cool before blitzing.
Basil — Weigh leaves after removing thick stems and spin-dry well; surface water thins the sauce.
Cheese — Parmigiano Reggiano aged ≥ 24 months gives the best flavor. Pecorino works if you like a sharper edge.
Olive oil — Choose a mild, fruity oil; very peppery oils can be too bitter.
Consistency tweaks — For pasta, whisk in 15–30 ml / 1–2 Tbsp cold water to loosen. Keep it thick for spreads or as a dip with crudités.
Processor vs. mortar — A mortar delivers a rustic, chunkier pesto; the food processor is faster and yields a smoother sauce.
Salt timing — Blend first, then taste; pistachios and cheese both contain natural salt, so you may need less than expected.
Fridge storage — Pack into a small jar, level the top, and cover with a 2 mm / ¹⁄₁₆ in olive-oil seal. Store at ≤ 4 °C / 40 °F and use within 3 days for peak color and flavor. Some cooks report acceptable quality up to a week if the oil film stays intact.
Freezer storage — Portion into silicone ice-cube trays, freeze solid, then bag the cubes. Quality holds for about 3 months at −18 °C / 0 °F. Thaw overnight in the fridge, or melt a cube straight into hot food.
Yield & scaling — This batch makes roughly 250 g / 1 cup—enough for 4 servings of pasta. Double or triple the recipe by maintaining the same ratios.
