Mix the peppercorns together on a plate. Season the steaks with salt then press lightly into the peppercorns on both sides. Place on a hot grill. Cook for 6-8 minutes, turning once for medium-rare. Let rest 3 minutes before serving.
For the aioli: In a food processor, add roasted garlic cloves, dijon and yolks. While processor is on, drizzle in oil, slowly at first until it emulsifies then more quickly. Add juice, salt and pepper and pulse to incorporate. Check for seasoning. Store in fridge.
For the fries: Bake the potatoes until fully cooked (about 45 minutes at 350 degrees, knife should slide off potato when pricked). In a sauce pan, add cream and garlic and reduce by 50 per cent on low heat, about 15 to 20 minutes. With a hand blender, mix well and check for seasoning. When the potatoes can be handled, scoop out flesh into a bowl. Fold in the cream, scallions and butter and hand mash. You can use a mixer fitted with a paddle. Check for seasoning. Spread mash on 1/2 sheet tray, 1/2" thick. Cover with plastic, top with another tray and press firmly. Chill overnight in the fridge. You may freeze the mash in 4 hours. Slice rectangular 'fries' (3x1/2x1/2). Dredge in flour, egg then panko. Fry at 350 degrees until GB & D, about 5 minutes. Season with salt.
For the salad: On 4 large plates, spread out the tomato like carpaccio slices. Drizzle lightly with oil and vinegar and season with Salt and pepper.
Plating: On the above tomato plates, stack the fries up and place steak in front. Serve the aioli in a ramekin for both the steak and fries.
