How to Make It
Bring milk to a simmer over medium heat in a medium, heavy saucepan. Add fish; cover and simmer for 5 minutes or until fish flakes easily when tested with a fork. Drain well. Combine fish, 1/4 cup panko, and next 8 ingredients (through 1 garlic clove); stir in 1 tablespoon juice. Divide fish mixture into 8 equal portions, shaping each into a 1/2-inch-thick patty. Dredge patties in remaining 1/4 cup panko, pressing to coat.
Heat 1 tablespoon olive oil in a large nonstick skillet over medium-high heat. Add 4 patties to pan, and cook for 4 minutes on each side or until golden. Remove from pan, and drain on paper towels. Repeat procedure with remaining olive oil and patties. Drizzle with remaining 1 tablespoon juice.
To prepare sauce, combine canola mayonnaise and remaining ingredients. Serve sauce with cakes.
