- 4 eggs, at room temperature
- 2 tbsp tamari
- 1 tbsp finely grated ginger
- 100 gm shiro (white) miso paste (¼ cup)
- 150 gm mixed mushrooms, such as oyster and shiitake, thickly sliced
- 50 gm enoki mushrooms
- 1 bunch (about 300gm) spinach, trimmed
- Furikake and shichimi togarashi (see note) and sesame leaves (optional), to serve
- 300 gm buckwheat flour, plus extra for dusting
- 100 gm plain flour (⅔ cup)
- 30 gm matcha powder, sieved
- 1For matcha noodles, combine flours, matcha and ½ tsp fine salt in a large bowl and mix to combine. Add 150ml water and mix with your fingertips. Gradually add another 150ml water, a little at a time, mixing until you have a soft but not sticky, dough (you may not need all the water). Turn out onto a surface lightly dusted with buckwheat flour and knead until smooth (4-5 minutes). Divide into 4 pieces and form each into a round. Roll each to a 2mm-thick rectangle, dusting generously with buckwheat flour as you go to prevent sticking. Lightly dust top of dough to prevent sticking, then fold in half and cut into 2mm-wide noodles with a very sharp knife. Or put through the tagliarini cutter on a pasta machine. Carefully unfold noodles and toss in buckwheat flour to prevent sticking.
- 2Cook eggs in a saucepan of boiling water for 7 minutes (for soft yolks), drain and run under cold water until cool enough to handle.
- 3Meanwhile, bring tamari, ginger and 1.5 litres water to a simmer in a saucepan. Whisk 250ml of the hot ginger liquid in a bowl with miso to combine, return to pan and simmer for flavours to combine (4-5 minutes; do not boil). Add mushrooms and spinach and simmer until spinach is just wilted (30 seconds to 1 minute).
- 4Blanch noodles in a large saucepan of boiling salted water until shiny and tender (30 seconds to 1 minute). Drain and divide among warmed serving bowls, then ladle broth, spinach and mushrooms over noodles. Crack eggs in half, scoop out of shells and add to bowls, scatter with furikake and shichimi togarashi and serve hot.
