How to Make It
In a medium saucepan, melt 2 tablespoons of the butter. Add the rice and cook over moderate heat, stirring for 3 minutes. Add 1/2 cup of the red wine and cook, stirring, until nearly evaporated, about 5 minutes. Add the stock and a pinch of salt and bring to a boil. Cover and cook over moderately low heat until the liquid is absorbed and the rice is tender, about 35 minutes.
Meanwhile, in a large skillet, melt the remaining 2 tablespoons of butter. Add the plums and cook over moderately high heat, stirring occasionally, until lightly browned, about 4 minutes. Add the remaining 1/2 cup of wine and the sugar and bring to a boil. Cover partially and cook over moderate heat until the plums are soft and the liquid is thick, about 4 minutes. Remove from the heat and stir in the shiso.
Preheat a grill. Rub the steaks with the olive oil and season generously with salt and pepper. Grill the steaks over a hot fire for about 15 minutes, turning occasionally, until an instant-read thermometer inserted in the center of a steak registers 125° for medium-rare meat. Let the steaks rest for 5 minutes, then snip off the strings. Transfer the steaks to plates and serve with the black rice and plum compote.
Chinese black rice is available at Asian markets or specialty stores.
