Make the onsen egg: Use a 4:1 ratio of boiling hot water to room temperature water. Gently nestle your room temperature egg into the water, lid it, and let it rest for 13-15 minutes. Finish with a refreshing cold water bath.
Make the sauce: In a small bowl, combine the garlic,sugar, oyster sauce, soy sauce, water, sesame seeds, and chilli oil. Stir well until everything is evenly mixed.
Prepare the tofu base: Carefully remove the silken tofu from its packaging and place it on a serving plate. Drain any excess liquid. Top with chopped spring onion and coriander.
Assemble: Crack the onsen egg gently over the tofu.Then, pour the sauce over everything. (If you’re unsure whether the onsen egg is cooked to your liking, crack the egg into a small bowl first before plating.)
Serve & enjoy: This dish is best enjoyed cold or at room temperature as a refreshing, savoury starter or side.
