Make the spicy sauce

• In a bowl, combine the gochugaru, soy sauce, sesame oil, grated garlic and sugar.
• Mix into a glossy chili sauce and let it sit for a moment so the flavors blend.

Prepare the tofu

• Drain the chilled silken tofu and place it in a serving bowl or on a plate.
• Slice it into large cubes or leave it whole.

Assemble and serve

• Spoon the spicy sauce generously over the cold tofu.
• Top with sliced scallions, toasted sesame seeds and chopped kimchi.
• Serve immediately while the tofu is still cold.
