Soba is what the Japanese call buckwheat, and also refers to the thin, grayish noodles that, in my opinion, are one of the best things to come out of Japan. It is usually served with soba tsuyu - a sauce made with shoyu-based (soy) dashi broth with mirin (rice wine) - along with a variety of condiments.
I first tried soba on a trip to Tokyo, Japan back in 2007. Here's a Tumblr entry about it:
It was actually aboard Japan Airlines on my way to Tokyo in 2007. My flight tray came with a teeny bowl of soba noodles and a cute bottle of soba sauce. The rest of the meal consisted of shrimp salad, a bread roll, butter, Kikkoman sauce, beef with veggies, and an ube dessert. The soba noodles were truly the highlight of that meal. I couldn’t believe noodles could be so good plain! It wasn’t even proper soba at that since it was instant airplane soba. From that day on, soba became one of my favorite foods.Since then, I've been obsessed. Unfortunately, soba is hard to find in my home country, the Philippines. There are so many Japanese restaurants here in Manila, but only a select few offer it on the menu. Sure, it's probably available at the more high end Japanese places, but I don't want to have to do fine dining every time I want soba. What I'm saying is, it's here, but it's not readily accessible. This is why it's the first thing I check whenever I try a new Japanese restaurant. I'm always on the hunt for it, and I'm totally thrilled whenever I find a place that has it.
