Finely chopped ginger and spring onion with salt, scalded with smoking oil — the sauce for white-cut chicken.
What makes it ginger and spring onion oil
Ginger and spring onion, chopped very fine.
Salt, and very hot neutral oil poured over so it sizzles.
Raw-tasting and bright, not fried brown.
Where it comes from
It's the dip served with baak chit gai — white-cut chicken, poached and served at room temperature — and it turns up spooned over noodles, rice and steamed fish too. The hot oil cooks the aromatics just enough to release them and no more.
