Can I make the soup ahead of time?
Yes. Prepare the soup through step 8 and refrigerate for up to 3 days. Reheat gently over low heat, stirring occasionally. Sear the shrimp and make tortilla chips fresh before serving.
What if I don't have an immersion blender?
Carefully transfer the soup in batches to a regular blender, blend until smooth, then return to the pot. Work in smaller batches to avoid overflow.
Can I substitute the Oaxaca cheese?
Yes. Use fresh mozzarella or quesillo as a direct swap for similar stretch and melting. Asadero cheese also works well in Mexican-inspired soups.
How do I know when the shrimp is cooked through?
Sear 1–2 minutes per side until the shrimp turns opaque and pink throughout. Do not overcook or they will become tough.
Can I use regular tortillas instead of flour tortillas for chips?
Corn tortillas work but will be more brittle. Cut and bake at 400°F for 12 minutes with a flip halfway through, same as flour tortillas.
