Clean and trim your mushroom, saving the trimmings. Break into 4 pieces and set aside. 

Wash the trimmings under water until very clean. Discard any that won’t come clean. 

Bring 6 cups of water to a simmer in a medium pot.

Add cleaned mushroom trimmings, ginger and peeled garlic cloves. 

Keep on a low simmer while you complete the rest of the recipe. 

Fill a large pot with water 3/4 full and bring to a boil on another burner. This will be for the eggs and noodles. 

Meanwhile, heat the oil in a frying pan over medium high heat, then add the mushrooms.

Let the mushrooms expel all of their water and keep cooking, pressing down with a spatula every once in a while until it begins to brown. Season generously with salt and pepper, then flip the mushrooms and sear on the other side. Both sides should be beautifully golden brown, this should take 10-15 minutes. 

Once done, set aside. 

Meanwhile, when the pot of water comes to a full boil, add the room temperature eggs, gently with a spoon. 

Set a timer for 6 minutes and 30 seconds exactly. 

When the timer goes off, remove the eggs from the boiling water with a slotted spoon and add them to a bowl of cold water or run them under cold water in the sink until they cool. Don’t discard the boiling water as you will be using it for the noodles, just turn the heat down to low. 

Peel the cooled eggs, then carefully slice in half. Try not to let the yolk run away on you. 

Set aside for the time being. 

Prepare all of your vegetables, leaving them in handy piles or in small bowls (this is called a mise en place) so they’ll be ready to add to the soup at the last instant. 

Remove the ginger, mushroom scraps, and garlic from the broth with a slotted spoon. 

Add the soy sauce, mirin, and sugar to the broth and stir to combine. Keep the broth on low so it doesn’t cool down.

Make sure all of the above steps are complete and everything is ready to go.

Bring the pot of water back to a boil and add soba noodles and a large pinch of salt. 

Cook according to package directions, or until al dente. Drain. 

Split the noodles evenly between 4 bowls. Ladle the hot broth over the noodles, leaving some space at the top of the bowl for you toppings.

Artfully arrange 1/2 an egg, 1 piece of mushroom, some sliced radishes and beets, sliced chili, and sliced green onions on top of the bowl. Sprinkle with chili flakes or shichimi and serve with a spoon and chop sticks. Enjoy!
