Common Mistakes to Avoid
Making Julia Child’s Creamy Potato Leek Soup can be easy, but a few common mistakes can affect the final result.
- Not cleaning leeks properly: Leeks can trap dirt and grit in their layers. Always slice and rinse them thoroughly under cold water to remove any hidden debris.
- Overcooking the leeks: Sautéing leeks too long can lead to caramelization instead of a soft texture. Cook them just until they are tender and translucent.
- Ignoring potato size uniformity: If your potato cubes are uneven, some may cook faster than others. Cut them into uniform 1/2 inch pieces for even cooking.
- Using too much cream: While cream adds richness, too much can overwhelm the soup. Stick to the recommended amount for a balanced flavor.
- Skipping the blending step: For that silky texture, blending is essential. Don’t skip it; an immersion blender makes this step easy and mess-free.
- Neglecting seasoning adjustments: Taste your soup before serving. Season with salt and pepper according to your preference for the best flavor.
