Cantonese Walnut Shrimp (He Tao Xia) — Honey Walnut Glaze

Overview

He tao xia (核桃虾) originated in Hong Kong in the 1980s and became the signature dish of Chinese-American restaurant culture. Prawns are velveted and deep-fried, then tossed in a creamy sweet mayonnaise sauce, served alongside honey-candied walnuts. The dish bridges Cantonese technique (velveting, deep-frying) with Western mayo. Its simplicity belies the precision required.

Flavour Context

Sweet, creamy, nutty; prawn sweetness enhanced by velveting; candied walnut provides caramel crunch; a rich, indulgent dish

Key Principles

{"Walnuts boiled briefly in water to remove bitterness, then candied in honey or sugar syrup","Prawns velveted: egg white, cornstarch, salt — 30 minutes minimum","Deep-fry prawns at 180°C until just golden — overcooking makes them rubbery","Mayo sauce: Japanese Kewpie mayo, condensed milk, lemon juice in 3:1:0.5 ratio","Toss prawns in sauce immediately before serving — sauce should coat but not pool"}

Pro Tips

{"Broccoli or honeydew melon served alongside provides freshness","Some HK restaurants add a thin batter to prawns for more crunch before frying","The condensed milk is non-negotiable — it is what distinguishes this sauce from plain mayo"}

Common Mistakes

{"Candied walnuts added too early — they soften in the sauce","Sauce too thick — should coat lightly, not clump","Overcooking prawns — they should be barely cooked, translucent at centre"}
