Step-by-Step Guide

1. Prepare the Potato Purée (Key for smooth texture)

① Cook & Strain

  • Peel and slice potatoes, boil until tender (~15 mins). Reserve 70g starchy water.

  • Press through a fine sieve while hot—no lumps allowed!

2. Emulsify the Base

① Combine & Heat

  • In a saucepan, whisk together:
    ▶ 250g potato purée
    ▶ 70g potato water
    ▶ 100g cream
    ▶ 20g olive oil
    ▶ 1g salt

  • Warm gently to 65°C/150°F (do not boil), stirring until glossy.

3. Charge & Stabilize

① Load the Siphon

  • Pour mixture into siphon, seal, and charge with 1-2 N₂O cartridges.

  • Shake vertically 5 times to integrate gas.

② Hold for Service

  • Keep in a 60°C water bath (foam will stay stable for 2 hours).

  • Dispense with a downward push for tight, cloud-like texture.


Chef’s Notes

✔ Why potato water? The starch enhances foam stability.
✔ Siphon hack: For extra volume, use 2 chargers and chill 10 mins before reheating.
✔ Pairings: Ideal with:

  • Truffle-infused mushroom soup

  • Seared scallops

  • Sous-vide beef tenderloin
