Udon with Lime Ginger Soy Sauce (Cold)

Udon with Lime Ginger Soy Sauce (Cold)

Last Updated on February 14, 2021

Summer time in Florida can be brutally hot but it’s nothing compared to the summer heat in Japan. It is super humid and all you crave is cold dishes like this! It is oil-free (except the natural oil of avocado) dish and it doesn’t leave you with a heavy stomach.

The dish has udon noodle in soy sauce based sauce made with ginger and lime, topped with avocado, red onion, cherry tomatoes, cabbages, scallions, and cilantro. Lime and cilantro add a Southeast Asian flavor to the Japanese udon. By the way, for many Japanese, cilantro is a very acquired taste ingredient. Actually, we use to hate cilantro as well but now we put it just about anything! Honestly, being vegan opens up our mind to many unknown territories and ideas. Also, we love any sort of raw onion-like flavor; red onion, scallion, shallots, chives just to name a few, so we tend to use a lot of them (we must smell really bad…) If you are not a big fan of such strong flavors, use a moderate amount.

For the udon noodle, we like thick ones for the hearty and chewy texture. Unfortunately, this type of udon noodle is available only in the freezer section in Asian markets where we live. But it’s not all bad.  It’s actually a great time savor since it’s already cooked and frozen so it takes only 60-90 seconds to be done! Of course, you can use any other types of udon noodle for this dish.

The sauce requires no cooking! Just put all ingredients together and it tastes great! We have a slight different preference in saltiness of food. Good news is that you can adjust the saltiness of the sauce just by adding more/less water! If you are not much of a saucy-person and ended up not using all the sauce, you can save it and use it later for stir-fry veggies or noodle which is what we did. We made stir-fried udon noodle the next day.
