Remove tough muscle from side of each scallop if necessary and halve any large scallops. On a sheet
of waxed paper combine flour, salt, cumin and cayenne and dip flat sides of each scallop into mixture to
coat, knocking off excess. In a skillet heat butter and olive oil over moderately high heat until foam
subsides and sautè scallops, flat sides down, until golden and just cooked through, about 2 minutes on
each flat side. Remove skillet from heat and cool scallops slightly.
In a large bowl whisk together lemon juice, extra-virgin olive oil, mustard, and salt and pepper, to taste,
until emulsified. Peel and pit avocado and cut into 1/2-inch-thick wedges. Cut wedges in 1/2 crosswise
and add to dressing. Add scallops with any liquid remaining in skillet, tatsoi, and Praline and gently toss
to coat.
For the praline:
In a bowl stir together pecans, salt, and cayenne. In a dry small heavy skillet or saucepan cook sugar
over moderate heat, stirring with a fork, until melted and cook, without stirring, swirling skillet or pan,
until a golden caramel. Add pecan mixture and stir to coat nuts with caramel. Spoon praline onto a
sheet of foil and cool. Transfer praline to a cutting board and chop fine. Praline can be made 3 days
ahead and kept in an airtight container.
