For the parsley root mousse, peel the parsley roots and cut them into pieces.
Rub the thyme leaves from the stems and sauté with the parsley roots and onions in a little nut oil. Deglaze with white wine and reduce to about ¼.
Then pour in the soup, add 2-3 drops of bitter almond oil and cook until the parsley roots are soft.
Stir in cream and simmer for another 5 minutes. Puree finely with a hand blender, season with salt, pepper and lemon juice.
Finally, mix in butter and crème fraîche with a hand mixer; air should be mixed into the soup.
Toast the flaked almonds until lightly golden brown without adding any fat. Garnish the parsley root soup with almond flakes and baked peas.
