Notes:

• Don’t skip the browning step—it’s crucial for developing deep mushroom flavor
• Make sure soup is completely cool before adding yogurt to prevent curdling
• Blend thoroughly for the smoothest texture—at least 2 minutes
• Full-fat Greek yogurt works best and won’t curdle as easily as low-fat versions
• Taste and adjust seasoning after chilling as flavors can mute when cold

Storage Tips:

• Keeps in refrigerator for up to 4 days covered
• Stir gently before serving as it may separate slightly while sitting
• Don’t freeze—the yogurt will separate and texture will be ruined
• Serve in chilled bowls for the best presentation and temperature contrast
