Japanese cucumbers are the best tasting, non-burp inducing cucumbers on the planet. They are slim and very dark green, with very few bumps on the skin. In Japanese, they are called kyuuri, or きゅうり。(Please let me know if I wrote that incorrectly, nihon no tomodachi.)
What I didn't know is that Japanese cucumbers, when fresh, have a delightful little magic to them. My good friend Tamie-san told me she was watching a cooking show on NHK that said when cucumbers are extremely fresh, you can break them in half by hand and then stick the cucumber back together. Doesn't that sound like a fun thing to try with your kids?
