How to Make It
In a small saucepan, combine the Cabernet and port and bring to a boil. Simmer over moderate heat until reduced to 2 tablespoons, about 15 minutes. Let cool slightly.
Set a medium metal bowl over a pot of simmering water. Put the egg yolks in the bowl and whisk over low heat until thick, about 2 minutes. Very gradually, whisk in the melted butter and whisk constantly until thick and creamy, 4 to 5 minutes. Whisk in the wine reduction and lemon juice in a thin stream and season with salt and pepper. Keep the hollandaise sauce warm over very low heat, stirring occasionally.
Heat a grill pan. Brush the steaks lightly with olive oil and season with salt and pepper. Grill the steaks over high heat, turning once or twice, until medium-rare, about 8 minutes. Let the steaks rest for 10 minutes.
Meanwhile, bring 2 large, deep skillets of water to a simmer. Crack 6 eggs into each skillet and simmer over moderately low heat until the whites are set and the yolks are runny, about 4 minutes. Using a slotted spoon, transfer the poached eggs to a plate; blot dry with paper towels.
Arrange 2 English muffin halves on each plate. Thinly slice the steaks, arrange the meat on the muffins and season lightly with salt and pepper. Top with the poached eggs. Spoon the hollandaise on top and serve right away.
