Basil King is a hawker stall at 302 Choa Chu Kang Ave 4 in Choa Chu Kang, Singapore 680302, and its 4.9 Google rating from 505 reviews makes it one of the neighbourhood's better-loved stalls. Stalls built on Thai-style basil cooking live and die by two things: the herb and the wok. The basil that matters is holy basil, which gives a peppery, clove-like edge rather than the sweetness of a supermarket bunch, and a good stall tosses its meat over fierce heat so it arrives glossy, lightly charred and properly fiery. Cooked to order is the sign to look for — if the wok roars when you order, you are in the right queue. Regulars dodge the noon rush and judge a stall by its fried egg: lacy, crisp-edged, yolk just set. For a quick, fiery lunch in Choa Chu Kang, a stall with a following like this one is reason enough to wander down Ave 4.
