Mushroom Foam

This earthy and aromatic mushroom foam is the perfect toping to wow your guests at your next dinner party. Foam magic is is the secret, creating a lacy foam that packs a punch of flavors.

Difficulty

Easy

Ingredients

  • 1532g (3 lb 6 oz) Assorted Mushrooms (Crimini, Button, Oyster, Shiitake, Portobello)
  • 1 sprig Thyme
  • 1 sprig Rosemary
  • 1 sprig Sage
  • 20g (1 Tbsp + 1 tsp) Salt (for Mushroom Jus)
  • 6g (2 Tbsp) Foam Magic

Equipment

  • Large 250 Micron Superbag
  • Heavy Bottom Pot
  • Measuring Cup

Timing

Active Time: 5 Minutes
Total Time: 50 Minutes

Yield

600g-1000g of Mushroom Jus

  • Prepare Mushrooms

    If you have any mushrooms that are especially dirty use a pastry brush to dust off any dirt. Do not wash mushrooms as they quickly become waterlogged.

     
    Place the mushrooms in a food processor and pulse 3 times. Do not over mix these as it is unnecessary. The mushrooms should resemble a rough chop.
  • Heat and Cover

    In a heavy bottom stock pot place all the mushrooms (stems and all), thyme, rosemary, sage, and 20g of salt.

    Cover and place over low heat.
     
    The mushrooms will quickly start to release their liquid. You do not need any oil for this, the salt and heat will do all the work.
     
    Allow the mixture to cook over low heat for 30 minutes. Stir every 5 minutes to check the progress of the mushroom jus.
  • Pour and Strain Mushroom Jus

    Pour the mushrooms into a large 250 micron superbag. Allow it to strain for 20 minutes when it cools.
     
    Squeeze the bag to draw as much liquid out of the mushrooms as possible.
     
    Measure 600g (21oz) of strained mushroom jus and allow it to cool to room temperature, about 30 minutes.
  • Create Mushroom Foam

    Whisk together the mushroom jus, foam magic.
     
    Place the mixture in a 2 quart container and use the magic air maker to create foam. Refrigerate until needed.
  • Serve

    It’s a good idea to serve the foam table side or right before serving as any fat can pop the bubbles in the foam.
     
    This sauce pares great with our Spring Pea Risotto recipe. Over time the foam should melt into the risotto.
