Ingredients

  • Pesto
  • ⅓ cup pine nuts ≈ 45 g
    Swaps for pine nuts

    Instead of nuts

    • Another nut: The same amount. Pecans are sweeter and softer, walnuts slightly bitter, almonds firmer and milder.
    • Toasted pumpkin or sunflower seeds: The same amount. Smaller and crunchier, with an earthy taste.
    • Leave them out, or use chocolate chips or toasted oats: The same amount (or none). Leaving nuts out doesn't change how a batter bakes.

  • 2 cloves garlic, peeled
    Swaps for garlic

    Instead of garlic

    • Garlic powder: ⅛ tsp for each clove. Mellower and sweeter, with no bite.
    • Jarred minced garlic: ½ tsp for each clove. Milder and slightly sour from the preserving liquid.

    More for garlic

  • 2 cups fresh basil leaves, packed
    Swaps for fresh basil leaves

    Instead of basil

    • Dried basil: 1 tsp dried for each 1 tbsp chopped fresh (a third as much). Flatter and more savory: dried basil loses its sweet, clove-like smell.
    • Spinach or arugula + parsley (for pesto): The same amount of greens. Greener and milder (arugula is peppery); still a good pesto.
    • Fresh mint or oregano: Half as much. Different but fresh; mint suits Thai dishes, oregano suits Italian.

    More for basil

  • ½ cup parmesan, finely grated ≈ 50 g
    Swaps for parmesan

    Instead of parmesan

    • Pecorino Romano: The same amount. Sharper and saltier (it is made from sheep's milk), so go easy on other salt.
    • Grana Padano: The same amount. Milder and a little softer, very close otherwise.
    • Nutritional yeast: 2 tbsp for each ¼ cup grated parmesan. Nutty and cheesy, but it doesn't melt or brown.

  • ½ cup extra-virgin olive oil
    Swaps for extra-virgin olive oil

    Instead of olive oil

    • Avocado oil or another neutral oil: The same amount. No olive flavor; avocado oil handles higher heat.
    • Butter: The same amount. Richer and nutty when browned.
    • A neutral oil + more seasoning: The same amount. Dressings lose the fruity, peppery note; a little extra lemon, garlic or mustard makes up for it.

    More for olive oil

  • 1 tbsp lemon juice
    Swaps for lemon juice

    Instead of lemon juice

    • Lime juice: The same amount. A different, more floral aroma; works almost everywhere.
    • Bottled lemon juice: The same amount. More sour and flatter; fine in cooking and baking, less bright in dressings and drinks.
    • White wine vinegar or white vinegar: Half as much. Sharper, with no citrus aroma.

    More for lemon juice

  • ¼ tsp kosher salt
    Swaps for kosher salt

    Instead of salt

    • Table salt or fine sea salt: About half as much as Diamond Crystal kosher, about ¾ as much as Morton kosher. The same saltiness when measured this way.
    • Salt by weight: 1 tsp is about 6 grams of table salt, 5 grams of Morton kosher, 3 grams of Diamond Crystal kosher. The most reliable way to swap, especially in baking and brines.

    More for salt

  • Pasta
  • 1 lb fusilli or penne
  • 1 tbsp kosher salt, for the pasta water

Steps

  1. Toast (how to toast) Toast Heat nuts, seeds, spices or bread crumbs in a dry pan or oven until fragrant and lightly browned. 1. Spread them in a dry skillet over medium-low heat, or on a sheet pan at 350°F.2. Shake the pan or stir often.3. Watch and smell: the moment they smell nutty, they are close.4. Tip them onto a plate right away; the hot pan keeps cooking them. Done when: They are fragrant and a shade darker. Small seeds take 1 to 3 minutes; nuts in the oven 5 to 10.

    the pine nuts in a dry skillet over medium-low heat, shaking the pan often, until golden. They burn quickly, so stay close.
    ⏱ Toast nuts: 3 min
  2. Tip the nuts onto a plate to cool.
  3. Bring a large pot of water to a
    boil (how to boil) Boil Heat liquid until big bubbles rise and break all over the surface. 1. Use a pot big enough that the water fills it no more than three quarters.2. Cover it to boil faster, over high heat.3. Salt pasta or vegetable water once it boils.4. Add the food, stir, and bring it back to a boil before you start timing. Done when: A rolling boil keeps bubbling hard even when you stir. Safety: Turn pot handles toward the back of the stove, and drain pasta into a colander in the sink, pouring away from you. Steam burns fast: lift lids and foil away from your face, tipping the far edge up first.How to boil water for pasta and vegetables: mistakes to avoid
    and add 1 tablespoon salt.
  4. Pulse the garlic and pine nuts in a food processor until finely chopped.
  5. Add the basil and parmesan and pulse until finely chopped, scraping down the bowl once.
  6. With the machine running, pour in the olive oil in a steady stream until the pesto is mostly smooth.
  7. Add the lemon juice and 1/4 teaspoon salt and pulse to mix.
  8. Cook the pasta until al dente.
    ⏱ Boil pasta: 10 min
  9. Scoop out 1 cup of the pasta water, then drain the pasta.
  10. Return the pasta to the empty pot off the heat. Add the pesto and 1/4 cup pasta water and toss until glossy, adding more water a splash at a time if it looks dry.
  11. Fold (how to fold) Fold Combine a light mixture (whipped cream, beaten whites) or chunky add-ins into a batter gently, so it stays airy. 1. Put the lighter mixture on top of the heavier one, or add the flour or chips.2. Cut a rubber spatula straight down through the middle to the bottom of the bowl.3. Sweep it across the bottom and up the side, then turn it over on top.4. Turn the bowl a quarter turn and repeat.5. Stop as soon as no streaks remain. Done when: There are no dry streaks or white blobs, and the mixture still looks light and puffy.

Tips

  • Toss the pesto with the pasta off the heat. Direct heat darkens the basil and makes the cheese clump.
  • Walnuts or almonds can stand in for pine nuts.
  • Parmesan is traditionally made with animal rennet. For a strictly vegetarian dish, choose a hard cheese labeled vegetarian.

Storage

Store extra pesto in a jar with a thin layer of oil on top, refrigerated up to 3 days, or freeze in an ice cube tray up to 3 months.

Whole packages, store brands, sales and regions all change the real cost: treat it as a ballpark.
