Use a vegetable peeler to peel Jerusalem artichokes or scrub well and leave the skin on for extra texture and nutrients. For a richer flavor, sauté with both butter and olive oil. To make the soup extra smooth, strain it after blending. Garnish with toasted pumpkin seeds or fresh herbs like chives or parsley. Variations include making it vegan by using vegan butter, adding coconut milk for creaminess, or seasoning with smoked paprika or fresh herbs.
