”彈牙” 英文點講?

I am not sure whether using Al dente would be confusing.
So, better commenting with delicious and flexible(柔韌的;有彈性的) together

”彈牙” 英文 Al Dente.....原來是意大利人形容意粉煮得爽口彈牙、有趙頭, 今日英語世界的飲食界(廚師)都採用了這外來語, 作為廚藝的專有名詞!
讀作(阿+L DENtay)

彈牙其實是廣東話獨有﹐如要用英文表達﹐可以說﹕

The texture of the fish ball is very elastic (or bouncy).

至於 chewy﹐其實是相反﹐是很 "un"﹐解作不易嘴嚼。

Grain of fish egg good ball tooth

我會話 : "Those are some chewy fish-balls!!"
Hope it helps
