Bánh rán: Hanoi's sesame balls, sweet and savoury
One dough, two completely different snacks — a savoury pork-filled ball and a sweet one with a hollow shell that rattles when you shake it. Plus how to tell a good fryer from a tired one.
Bánh rán is a sphere of glutinous rice dough, rolled in sesame seeds and deep-fried. That is the entire specification, and out of it Hanoi gets two snacks that have almost nothing in common.
They sit in the same tray, at the same stall, cost roughly the same, and if you order without knowing the difference you will get whichever the vendor reaches for first.
Bánh rán mặn — the savoury one
Inside: minced pork, glass noodle, wood-ear mushroom and shallot — essentially the filling of a nem rán, packed into a ball instead of a roll.
The shell is chewy rather than crisp; glutinous rice flour does not shatter the way wheat pastry does. The sesame crust gives it a thin layer of crunch and a toasted note. Biting in, you get a springy give, then the savoury filling.
Served with: the standard nước chấm — diluted fish sauce, sugar, lime, garlic, chilli, with green papaya slivers — and usually a plate of herbs.
How to eat it: halve it with chopsticks or teeth, dip the cut side, eat. Some stalls pre-cut. Wrapping in a lettuce leaf with perilla, as with bánh gối, works well and cuts the richness.
Price: 8,000–15,000 VND each. Order three.
Bánh rán ngọt — the sweet one
Inside: sweetened mung bean paste, sometimes scented with jasmine or grapefruit flower.
The shell is glazed rather than plain — fried, then rolled in a light sugar syrup that sets into a thin lacquer. Sweeter, stickier, and a different eating experience entirely.
Bánh rán lúc lắc
This is the one to ask for by name, and the reason is charming.
“Lúc lắc” means “rattling”. In the properly made version, the dough shell puffs and separates from the filling during frying, leaving a hollow gap. The mung bean ball sits loose inside the shell, and if you shake it gently next to your ear, it rattles.
That is the quality test, and it is a real one — the rattle means the dough was mixed and fried correctly. A solid, silent bánh rán ngọt is not wrong, just less skilfully made.
Say: “Có bánh rán lúc lắc không?” — do you have the rattling kind? Then shake one before you eat it. Vendors find this completely normal and will often shake one for you to demonstrate.
Price: 5,000–12,000 VND each.
Reading a fryer stall
Bánh rán comes from the same pavement wok as bánh gối, nem chua rán and spring rolls — the fryer corner, which gets its own treatment in the bánh gối article.
Three things to check before you sit down:
Is the oil moving? A wok with nothing in it and a full tray beside it means the shift is winding down. What is in that tray has been there a while.
What colour is the oil? Pale gold is good. Very dark brown means it has been used all day or longer, and everything coming out of it will taste of it.
How high is the tray? A stall selling well keeps a low tray, because things leave as fast as they arrive. A tray piled high at five in the afternoon is a stall with a demand problem.
If what you are handed is not hot, say “rán lại giúp em” — please re-fry it. This is a completely normal request and most vendors will do it without comment.
Where to look
The Old Quarter, from mid-afternoon. Alley entrances and corner stalls. The area around the cathedral has the highest concentration and the most visitors; the unnamed stalls three streets away are cheaper.
Near school gates, around 4 to 5pm citywide. Bánh rán is children’s after-school food as much as anything, and school-gate stalls have the fastest turnover in the city — which, by the tray test above, makes them reliably good.
Markets, in the morning, for the savoury version specifically.
When
Afternoon, roughly 2 to 7pm, peaking around four when school finishes.
Some market stalls sell bánh rán mặn from mid-morning. The sweet version is almost entirely an afternoon thing.
Ordering
“Cho em ba cái bánh rán mặn” — three savoury bánh rán. “Hai cái ngọt” — two sweet ones. “Có lúc lắc không?” — do you have the rattling kind? “Rán lại giúp em” — please re-fry these.
Ordering both kinds together is completely standard. The usual pattern is savoury first, sweet to finish, with iced tea throughout.
What a good order looks like
For two people at a fryer corner, around four in the afternoon:
- 4 × bánh rán mặn
- 2 × bánh rán lúc lắc
- 2 × trà đá (iced tea, usually 3,000–5,000 or free)
That is roughly 70,000 VND total, takes half an hour, and is the correct way to bridge lunch and dinner in this city.
If you only do one thing
Find a stall with moving oil and a low tray at four in the afternoon. Order savoury first, then ask for the rattling one.
Shake it before you eat it. If it rattles, you have found a good fryer, and you should remember where it is.
Next: duck and goose — bún măng vịt, bún ngan and the ginger sauce.
