Can I make this soup ahead of time?
Yes. Prepare through step 10 (before adding the cheese), then cool and refrigerate. Reheat gently over low heat, add the panela cheese in step 13, and finish with cilantro. The cheese is best added just before serving to maintain texture.
What cheese can I use if I can't find queso panela?
Queso fresco, Oaxaca cheese, or mozzarella work as substitutes. Panela's mild flavor and high melting point are key; avoid aged or sharp cheeses that will overpower the poblano and tomato base.
Do I have to roast the poblano peppers?
Yes. Roasting until the skin blisters (step 1) is essential—it adds smoky depth and makes peeling easier. Skipping this step will significantly alter the soup's signature flavor.
How do I know when the potatoes are done?
Test with a fork (step 7). They should be tender enough to break easily but still hold their shape so they don't break apart in the broth.
Why do I rub the Mexican oregano between my hands before adding it?
Rubbing the dried oregano releases its essential oils and flavor, intensifying the herb's taste so it distributes more evenly throughout the soup (step 11).
