Scallop Tostadas Recipe

Mash the avocado in a small bowl with tomato, red onion, cilantro, lime juice, salt, and pepper to taste.

Season scallops with salt and black pepper. Add the butter and oil to a 12-inch skillet on high heat.  Once the butter begins to smoke, gently add the scallops, making sure they are not touching each other.

Sear the scallops for 1½ minutes on each side. The scallops should have a ¼-inch golden crust on each side while still being translucent in the center.

Spoon the guacamole onto the tostada, top with scallops, and drizzle with sour cream.
