For the broth add the dashi to the boiling water in a pan. Bring to a gentle simmer
In a bowl mix together the miso paste, soy sauce, tahini, ginger and garlic. When combined, add a few large spoonfuls of the dashi from the pan, whisk until smooth and then tip the whole lot back into the pan. Taste and adjust the seasoning adding more soy if it needs a bit more. Add the noodles to the broth, the pakchoi, the mange tout and cook for a few minutes to soften and for the noodles to cook.
For the tofu gently pull it into small chunks with your hands (this just gives the tofu pieces a unique shape and texture that holds onto the sauce really well). Place the chunks in a bowl, and sprinkle with cornstarch and give it a few gentle tosses to coat.
In a nonstick pan over medium high heat, heat the olive oil and then add the tofu pieces. Leave for a few minutes to get really nice and brown and crispy. Flip until it’s all browned and crispy.
Finally, add the soy sauce, garlic, sugar and mirin to the tofu and allow to bubble for a few minutes until it reduces and goes lovely and sticky.
To serve, separate the noodles into two bowls and pour over the liquid. Add the sticky tofu and all the toppings, my favourite being the softly boiled egg, and enjoy!
