Common Mistakes to Avoid
Making Lemon Lentil Soup is simple, but a few common mistakes can affect the outcome. Avoid these pitfalls for a delicious result.
- Using old lentils: Old lentils may not cook properly and can lead to a mushy texture. Always check the expiration date or use fresh lentils for the best results.
- Skipping the aromatics: Neglecting to sauté onions, garlic, and other aromatics diminishes flavor. Take time to cook them until fragrant before adding liquids.
- Not adjusting seasoning: Failing to taste and adjust seasoning can leave your soup bland. Always check the flavor before serving and add salt, pepper, or lemon juice as needed.
- Ignoring cooking times: Overcooking or undercooking lentils affects their texture. Follow cooking times closely and check for doneness regularly.
- Lacking creaminess: If you prefer a creamy soup but skip blending part of it, you might miss out on that texture. Blend some of the soup to achieve creaminess while keeping some chunks for substance.
