Chilled umeboshi somen is my favorite summer recipe! It's a cool bowl of somen noodles topped with tangy, salty-sour umeboshi, and comes together in under 10 minutes!
Prepare the Umeboshi: Remove the pits from the umeboshi and mash them into a paste.
Cook Somen Noodles: Boil plenty of water (not listed in the ingredients) in a medium saucepan, add the somen noodles, and cook according to the package instructions (usually 1–2 minutes). Stir the noodles with chopsticks to separate them while cooking. Drain the noodles in a strainer and rinse under cold running water to cool and remove excess starch.
Prepare the Mentusyu: Dilute the mentsuyu with cold water according to the instructions on the bottle (ratios vary by brand).
Serve: Arrange the chilled somen noodles in a bowl. Top with mashed umeboshi and a sprinkle of katsuobushi. Drizzle the diluted mentsuyu over the top and enjoy!
Notes
Boil with plenty of water to keep noodles from sticking.
Rinse under cold water right after boiling to stop cooking and remove starch; this makes them firm and chewy.
