Selecting the Best Tuna
When choosing your tuna, visit a reputable fishmonger and ask for sushi-grade tuna. The freshness of the tuna is crucial to the success of this dish.

Preparing the Tuna
Start by slicing the tuna into thin pieces. This helps to achieve the right texture and allows the flavors to permeate each slice evenly.
Assembling the Crudo
Lay the tuna slices on a platter, drizzle with olive oil, and squeeze fresh lime juice over the top. Scatter finely sliced jalapeños across the tuna. Season with salt and pepper to taste. For added depth, consider a sprinkle of sesame seeds or a dash of soy sauce.

FAQ
Can I use frozen tuna for this recipe?
While fresh, sushi-grade tuna is recommended for the best flavor and texture, you can use high-quality frozen tuna if it’s all that’s available. Be sure to thaw it properly in the refrigerator and pat it dry before slicing. The texture may differ slightly, but it can still be a delicious option for this crudo.
How can I reduce the heat of the jalapeños?
To reduce the heat of jalapeños, you can remove the seeds and inner membranes, where most of the heat resides. Additionally, soaking sliced jalapeños in cold water for about 15 minutes can help mellow their spiciness. If you’re still concerned about heat, consider substituting with a milder pepper like a bell pepper.
