Common Mistakes to Avoid
Making roasted tomato soup may seem simple, but it’s easy to overlook key steps. Here are some common mistakes to keep in mind.
- Skipping the roasting: Not roasting your tomatoes can lead to a bland flavor. Always roast them until they char slightly to enhance their sweetness.
- Ignoring seasoning: Under-seasoning can make your soup taste flat. Taste as you go and adjust with salt, pepper, or even a bit of sugar if needed.
- Overlooking the broth choice: Using low-quality broth can impact the overall taste of your soup. Opt for homemade or high-quality vegetable or chicken broth for the best flavor.
- Not blending enough: Failing to fully blend the soup results in a chunky texture instead of a creamy consistency. Blend until completely smooth for a luxurious mouthfeel.
- Using stale bread for toasts: Old bread won’t give you the crispy texture you want. Use fresh baguette slices for the best results.
