Introduction: The Alchemy of Fish and Citrus
As a former biomedical researcher turned culinary school instructor, I am always fascinated by the scientific processes that occur in the kitchen. One dish that truly showcases the magic of chemistry is ceviche. Originating in South America, this dish involves marinating raw fish in citrus juices, which actually “cooks” the fish through a process called denaturation. Let’s dive into the chemistry of ceviche and explore the intricate dance of acid-base reactions in fish.
Ingredients
- 1 lb fresh white fish (such as halibut or sea bass), diced into small cubes
- 1 cup fresh lime juice
- 1/2 cup fresh lemon juice
- 1/2 red onion, thinly sliced
- 1 jalapeno, seeded and minced
- 1/4 cup chopped cilantro
- Salt and pepper to taste
Instructions
- In a non-reactive bowl, combine the diced fish, lime juice, and lemon juice. Make sure the fish is fully submerged in the citrus juice, as it is the acid that “cooks” the fish.
- Cover the bowl and refrigerate for at least 30 minutes, stirring occasionally to ensure even “cooking”. The fish is ready when it turns opaque and firms up.
- Once the fish is “cooked” to your liking, drain off most of the citrus juice. Add the red onion, jalapeno, cilantro, salt, and pepper. Gently toss to combine.
- Let the ceviche marinate in the fridge for another 15 minutes to allow the flavors to meld together.
- Serve the ceviche chilled, garnished with extra cilantro. Enjoy this refreshing and flavorful dish!
