Refreshing Cold Soba Noodles with Lime Zest

In this dish, the earthy profile of classic Zaru Soba meets the bright acidity of lime. While Japanese cuisine traditionally uses yuzu or sudachi, lime makes an excellent substitute, adding freshness to the deep, salty umami of the soy sauce. The heat of wasabi clears the sinuses and highlights the aromas.

Instructions

1

Boil the soba noodles in water for 3-4 minutes (or per package instructions).

Tip: Soba is ready when the center is no longer hard but still has a bite.
2

Drain and wash thoroughly under cold water, scrubbing gently as if washing clothes.

Tip: Cooling 'shocks' the noodles and seals the surface so they don't get soggy.
3

Make the dressing: mix the soy sauce, mirin, water, and freshly squeezed lime juice.

Tip: Balance between the acid (lime) and salt (soy) is key—taste as you go!
4

Slice the green onions into rings and toast the sesame seeds in a dry pan for a few seconds.

Tip: Toasting releases the oils in the seeds, resulting in a more intense aroma.
5

Serve the noodles drizzled with the sauce (or on the side), sprinkled with onions and sesame seeds. Add a pea-sized amount of wasabi on the side.

Tip: In summer, serve over ice cubes to keep the noodles cold.

Recipe FAQ
