Ceviche made with fresh, raw tuna chunks. Great as an appetizer or side dish. I learned this one from my grandparents and found it to be a winner among my college buddies.
1. **Tuna Quality is Paramount:** Always use sashimi-grade tuna for ceviche. Its freshness is critical for both safety and the desired silky texture. Avoid previously frozen or lower-quality fish.2. **Mind the Marination:** The lemon juice 'cooks' the tuna through denaturation. While 2-3 hours is standard, keep a close eye on it; over-marinating can result in a rubbery texture. For a more delicate experience, a shorter 1-hour marination is often sufficient.3. **Flavor Balance:** The final taste test is key. Adjust lemon juice for brightness and soy sauce for umami and salinity. A touch of finely chopped cilantro or a drizzle of good quality extra virgin olive oil can elevate the flavors and presentation.
