In a bowl, place egg yolks, sugar, and miso paste
Mix well until the ingredients all combine and sauce becomes creamy. Set aside to use later
In a pan, cook bacon pieces. Wipe off excess oil if needed.
Cook udon according to package instructions. I am using frozen udon, heated it up in the microwave for 2 minutes.
Add in cooked udon noodles with the bacon and mix well to combine
Turn off heat and add in cheese, miso mixture, and water.
Combine well until the udon and sauce emulsifies
Plate and add on toppings of choice
Serve while hot and enjoy
