Grilled Canadian Geoduck with satay garlic butter and “battera-style” avocado sushi

“Battera-style” Avocado Sushi: If you have a battera mould, layer in a layer of sushi rice, spread some mayonnaise on the rice, arrange a layer of sliced avocado on top, season with some salt and pepper, then add another layer of rice and press until well-packed. Cut the sushi into squares or rounds, place on serving plates and garnish with a sprinkle of nori and toasted sesame seeds on top and decorate with some radish sprouts. If you don’t have a battera mould, line a small straight-sided ramekin with a sheet of cling film large enough to cover the top of the ramekin once it is filled. Fill the bottom of the ramekin with a ½-inch/1-cm layer of seasoned sushi rice, pressing down gently and evenly all around. Spread some mayonnaise on the rice and layer in slices of avocado. Season with salt and pepper. Top with another layer of rice. Fold the cling film over to cover the layers of rice and avocado like wrapping a parcel. Press the “rice cake” with the bottom of a smaller ramekin until the layers are tightly packed. Invert the ramekin to de-mold the sushi gently. Remove and discard the cling film and plate as above. Repeat for each portion. Satay Garlic Butter: Combine butter, satay paste, garlic and cooking wine in a glass bowl and heat in microwave oven for about 30 seconds or until warm. Mix well. Or place ingredients in a small saucepan, stir and heat until warm. To Assemble: Heat a grill or a grill pan over medium high heat. Place the skewers of geoduck on the grill and press down lightly with a spatula for about 15 to 20 seconds. Using a basting brush, baste the skewers evenly with the melted satay butter. Turn skewers over, baste and cook the other side for 30 seconds. Transfer skewers to garnished serving plates and serve immediately.
