  • 1 pound Spaghetti (dry)

  • 2 cups Fresh Basil Leaves (loosely packed)
  • 0.25 cup Walnuts (lightly toasted)
  • 0.25 cup Almonds (lightly toasted, roughly chopped)

  • 1 tablespoon Mirin (real Japanese mirin; if unavailable, use sake or dry sherry)
  • 1 teaspoon Kosher Salt (plus extra for pasta water)
  • 1 pinch White Pepper (freshly ground if possible)

Instructions

  1. Boil the Pasta

Critical Success Points

  • Properly salt the pasta water to flavor the noodles.
  • Blend the pesto just until smooth; over‑processing can make it gummy.
  • Emulsify the pesto with starchy pasta water to achieve a glossy coating.

Safety Warnings

  • Handle hot boiling water with care to avoid burns.
  • Use a sharp knife when trimming scallions; keep fingers tucked.

technical
Q

Can I make Japanese Miso Pesto ahead of time and how should I store it?

technical
Q
