How to Make It
In a small bowl, combine the yuzu kosho with the ginger, garlic, lemongrass, cilantro and olive oil. Spread half of the pesto on the shrimp and let stand for 10 minutes.
Light a grill or preheat a grill pan. Grill the shrimp over high heat, turning once, until lightly charred and cooked through, about 4 minutes. Transfer the shrimp to plates and serve with the remaining pesto.
Yuzu kosho is available at Japanese markets and from chefshop.com.
