Reading the bitterness

The Ministry of Education, Culture, Sports, Science and Technology's food composition database records yamaudo as the stem of the outdoor-cultivated form of Aralia cordata. In Niigata Prefecture's introduction to Aga Town's 「山うどの油炒め」 (in translation: "stir-fried yamaudo with oil"), distinctive fragrance and bitterness, and a crisp texture, are given as the dish's defining character. The bitterness referred to here is not an intensity measured numerically, but a taste term used in an official cooking introduction.

Niigata Prefecture's recipe for 4 servings peels 800 g of yamaudo, cuts it into 5 mm-thick strips, and soaks it in water. This is stir-fried in oil and seasoned with sugar, soy sauce, miso, and shichimi pepper. There is also a caution that over-frying removes the crisp texture, making this a construction that retains texture while going through water-soaking and heating. The water-soaking and stir-frying times are not shown.
