📝 About This Recipe

This avant-garde palate cleanser marries the ancient tradition of Japanese tea ceremonies with the theatrical chill of modern molecular gastronomy. Each bite features a flash-frozen, ultra-crisp outer shell that shatters upon contact to reveal a silky, weightless lime and matcha heart. It is a sensory journey of temperature and texture, offering a vibrant acidity balanced by the earthy, umami-rich notes of premium green tea.

🥗 Ingredients

The Green Tea Infusion

  • 2 teaspoons Ceremonial Grade Matcha Powder (sifted to remove lumps)
  • 100 ml Whole Milk (high quality)
  • 50 grams Granulated Sugar

The Lime Base

  • 60 ml Fresh Lime Juice (strained of pulp)
  • 1 tablespoon Lime Zest (microplaned finely)
  • 250 ml Heavy Cream (chilled)
  • 2 large Egg Whites (at room temperature)

The Cryogenic Element

  • 3-5 liters Liquid Nitrogen (handled with extreme safety precautions/cryo-gloves)

Garnish and Finish

  • 1 sheet Edible Gold Leaf (for a touch of luxury)
  • 6 pieces Dehydrated Lime Slices (wafer thin)
  • 1 pinch Maldon Sea Salt (to brighten the flavors)

👨‍🍳 Instructions

  1. 1

    In a small saucepan, gently heat the milk and granulated sugar over medium heat until the sugar is fully dissolved. Do not let it boil.

  2. 2

    Whisk the sifted matcha powder into the warm milk vigorously until no clumps remain and the liquid is a vibrant, uniform green. Set aside to cool completely.

  3. 3

    Once the matcha base is cool, stir in the fresh lime juice and finely grated lime zest, ensuring the acidity is well-integrated.

  4. 4

    In a separate chilled bowl, whip the heavy cream to soft peaks. Be careful not to over-whip; you want a velvety texture, not butter.

  5. 5

    In another clean bowl, whisk the egg whites until they form stiff, glossy peaks. This provides the aeration necessary for the 'mousse' effect.

  6. 6

    Gently fold the matcha-lime mixture into the whipped cream using a silicone spatula. Use a light hand to maintain the volume.

  7. 7

    Carefully fold the egg whites into the cream mixture in three additions. The final mousse should be airy and light green.

  8. 8

    Transfer the mousse into a high-quality whipping siphon (ISI bottle). Charge it with two N2O (nitrous oxide) chargers, shaking vigorously after each charge.

  9. 9

    Refrigerate the siphon for at least 30 minutes to stabilize the foam and chill the fats.

  10. 10

    Prepare your cryogenic station: Pour the liquid nitrogen into a vacuum-insulated stainless steel bowl or a specialized Dewar.

  11. 11

    Dispense a small 'golf ball' sized sphere of mousse directly from the siphon into the liquid nitrogen. It will sizzle and boil rapidly.

  12. 12

    Using a slotted stainless steel spoon, gently rotate the mousse sphere in the nitrogen for 15-20 seconds. You are looking for a frozen exterior while maintaining a soft, creamy center.

  13. 13

    Remove the sphere and place it on a chilled serving plate. Let it 'temper' for 10 seconds so it doesn't stick to the guest's tongue.

  14. 14

    Quickly garnish with a tiny fragment of gold leaf, a dehydrated lime slice, and a microscopic pinch of Maldon salt.

  15. 15

    Serve immediately. Instruct the guest to eat the entire sphere in one bite to experience the 'dragon's breath' effect and the textural contrast.

💡 Chef's Tips

Always use ceremonial grade matcha; culinary grade can be too bitter for this delicate mousse. Ensure your siphon is well-chilled, as the fat in the cream needs to be cold to hold the aeration. Safety first: Always wear goggles and cryo-gloves when handling liquid nitrogen to prevent cold burns. If the mousse sticks to the spoon, dip the spoon in the nitrogen first to 'prime' it. Do not over-freeze the spheres; if they stay in too long, the center will turn into an ice block rather than a mousse.

🍽️ Serving Suggestions

Pair with a chilled glass of Junmai Daiginjo Sake to complement the umami notes. Serve as an 'intermezzo' or palate cleanser between a seafood course and a heavy meat course. Accompany with a light ginger-infused sparkling water. A small side of fresh raspberries can provide a beautiful color contrast and extra tartness.
