Reading the bitterness
「明日葉」 (ashitaba, Angelica keiskei) grows wild in the Izu Islands. A Cabinet Office record introducing island tourism and culture lists it as a regional specialty used in a wide range of dishes, including ohitashi (blanched greens) and tempura. The record concerns its use as an ingredient and says nothing about bitterness itself; within the material checked here, whether ashitaba is a bitter ingredient remains unsubstantiated.
The same official record names tempura as one dish made with ashitaba. It is a regional introduction, however, not a recipe giving detailed ingredient proportions or steps, nor a quantitative study of how often each dish is made or how bitter it is.
