Pesto Pearls

Herbaceous and savoury, pesto pearls burst with basil, garlic, and Parmesan flavour — a modern garnish for pasta, mozzarella, and grilled vegetables.

Ingredients

  • ¼ cup (60mL) pesto sauce (smooth, strained)
  • ¾ cup (180mL) cold water
  • 1 tbsp (15mL) lemon juice (to brighten)
  • ½ tsp (2g) sodium alginate
  • 1½ tsp (6g) calcium chloride
  • 2 cups (500mL) ice-cold water (for bath)

Instructions

  1. Prepare Base
    • Blend pesto with cold water and lemon juice until smooth. Strain through a fine sieve or cheesecloth to remove solids.
  2. Add Alginate
    • With blender on low, sprinkle in sodium alginate. Blend 1 minute until fully dissolved.
  3. Rest
    • Let mixture sit for 30–45 minutes to reduce bubbles.
  4. Strain
    • Push through a fine mesh sieve into The Spherificator®.
  5. Prepare Bath
    • Dissolve calcium chloride in ice-cold water.
  6. Form Pearls
    • Drop into bath and cure for 45–60 seconds.
  7. Finish
    • Rinse gently and chill. Use fresh or within 6 hours.

Expert Tips

Flavor Variations
  • Nutty: Add extra pine nut water or almond milk for smoother texture.
  • Spicy: Blend in arugula or a dash of chili oil.
Color Tips
  • Vibrant green: Blanch basil before making pesto.
  • Glossy pearls: Strain thoroughly and chill before forming.
Troubleshooting
  • If gritty: Re-strain and use only fine, smooth pesto.
