• 1/2 tablespoon dry thyme
• 2 tablespoons garlic powder
• 1 cup panko

Roast garlic: Heat oven to 350 degrees. Slice off top of garlic head to expose cloves. Place on piece of foil. Drizzle with olive oil and wrap tightly. Roast until cloves are lightly browned and tender, about 30 minutes.

Keep oven heated at 350 degrees. Remove garlic from skin. Mash, then mix paste with butter. Set aside.

Brush tilapia with garlic butter and coat with herb mixture. Bake 10 minutes per half-inch thickness. Serves 1.

Vinaigrette: Make a lemongrass-basil oil by steeping a stalk of lemongrass and 1/2 cup tightly packed basil in 1-1/2 cups vegetable oil for 2 hours on low heat. Remove lemongrass and basil and blend oil with 1 diced sweet onion, 1/4 cup vinegar, 2 cups basil leaves, 2 tablespoons each honey and mustard, and 3 tablespoons each sugar and lemon juice. Season with salt and pepper; stir in 1-1/2 tablespoons sesame seeds. Serve with fish.
