If you’re looking for dessert on the richer side, something deep fried never fails to deliver. This sesame balls recipe (Vietnamese bánh cam) delivers with a crispy golden glutinous rice outer shell, filled with sweet mung beans, and covered in white sesame seeds.
My grandmother was a child raising machine. As if raising nine of her own kids wasn’t enough of a challenge, she had her hands in raising almost all of the grand-kids too. Between cleaning up our messes and playing referee to our disputes, it seemed like she never skipped a beat in the kitchen.
In the very rare cases something wasn’t bubbling on the stove, grandma sometimes fed us a pulverized mix of roasted sesame seeds and salt (muối mè) over rice. Sounds like peasant food, right? Tasty peasant food. This is when I probably had my first taste of sesame seeds.
Does anyone really know where sesame seends come from (Any Mitch Hedberg fans?)? These crunchy little teardrop-shaped seeds cover the snack we’re going to be making today–bánh cam (sesame balls).
The name bánh cam literally means “orange cake” because these balls simply resemble oranges, not because there are any actual oranges in it.
There’s wonderful harmony in bánh cam. The outer shell is a warm golden brown color covered in white sesame seeds. The exterior has a satisfying crispiness to it from frying. On the other side of that surface is a lightly chewy or springy glutinous rice dough and a sweet ball of mung bean. Fans of bánh cam can get pretty picky about this balance between the crisp and chew.
Although they look very similar, there are differences between bánh cam from the South and bánh ran from the North. Both styles can be found throughout the country though. My parents recount the differences in these fried desserts back home:
North Vietnam – Bánh Rán
Northerners call it bánh ran, or “fried cake”. These are made with a Jasmine flower essence for a nice aroma. A sugary drizzle on these fried goodies can be found on them depending on the vendor.
Another difference in the north is that when they are covered in sugar, the dough is made only with sweet rice flour and no rice flour, sesame seeds, or potatoes.
South Vietnam – Bánh Cam
In this post, I make it in the Southern style. There is no essence of flower added to this. The most popular flavor added to the mung bean filling is with drops of vanilla extract.
Only in the South will you find freshly shredded coconut in the filling too, but that will vary by vendor. If you add coconut to your recipe, do yourself a favor and use only freshly grated coconut!
Shaped By Necessity
In many cases, money determines how things pan out. We add potatoes to prevent bánh cam from exploding in the fryer. Since potatoes were scarce (expensive) in Vietnam so sweet potatoes were used instead. This increased the sweetness allowing the cook to save money by cutting back on sugar too.
For the mung bean filling, my parents swear no cooks or snackers cared for some detail such as if the ball of mung bean shakes inside or not. There’s more air inside when you make the filling smaller and it’s highly likely cooks did that to stretch their daily supply.
Preparing the mung beans
Soak the dried mung beans. There’s two ways to hydrate them. The faster way: add hot water to soak them on the kitchen counter, drain then replace the hot water twice over the course of two hours.
The slower and easier way: add hot water to the beans, let it cool, the transfer to the fridge overnight.
Then when hydrated, drain and cook. Steaming is the simplest way to cook them because you just let it sit on medium heat, and don’t have to worry about stirring, or how much water you’ve added.
You can cook this on the stove, or in a rice cooker, just as you’d cook rice but it can be more finnicky to do it right, and you may lose a lot of beans sticking to the pot.
They’re done when no longer crunchy, and easily mash between your fingers, about 30 minutes.
How To Serve
These were usually sold by vendors as a snack. Locals rarely could afford more than one of these. They were maybe the size of a small orange–large enough to satisfy a dessert craving.
It’s fun to flatten bánh cam into a disk before taking a bite, but I also like making them into little bite-sized poppers too. These are excellent served with coffee or tea.
It took a lot of recipe tinkering with mom to get to this recipe. The adjustments were made to get a better crisp in the shell, and to develop a deeper brown color. The amounts of sugar are made so it’s not too sweet.
Filling ingredients – Adjusting sugar for the filling is easy, but it may change the texture and color if you adjust too much for the outer dough. I tried the mung bean filling with vanilla too, but prefer it without.
Shell ingredients – I have also tried using boiled potato instead of flakes, and it didn’t turn out as well. It probably has to do with getting the water levels right, but there was much better success for me with potato flakes. There are some legit local vendors who make it with boiled potatoes and their bánh cam is excellent.
Prepping ahead & storage – Before rolling and frying, the dough keeps in the fridge for a few days just fine. If you don’t eat too many of these at a time, it’s better to fry up fresh batches. After you fry these sesame balls, they do keep okay for a day or two. To reheat them, pop ’em in a toaster oven, or re-fry them in oil.
What are sesame balls made of?
Vietnamese bánh cam is a mix of a glutinous rice flour, regular rice flour, and a wheat flour crispy outer layer with a soft and sweet mochi-like mung bean center.
What do sesame balls taste like?
Sesame balls have a crispy and roasted sesame exterior and it gives you a sweet mung bean flavor when you bite down.
Chinese Sesame Balls?
The Chinese version of these sesame balls look very similar. I see these most of the time on dim sum carts. The filling is usually a red bean paste, black bean paste, taro, or lotus seed. The recipes I see there typically use more water in the filling so it’s more of a paste.
When you bite into the sesame ball you’ll usually find it more smashed and stuck to the wall of the outer shell compared to the consistency we go for in this recipe. The drier target of this recipe usually has the filling maintain it’s shape and sometimes you can hear it shaking around inside.
Outer Shell (Vỏ)
- 4 oz glutinous rice flour
- 0.75 oz rice flour
- 0.75 oz all-purpose wheat flour
- 5 tbsp potato flakes from boxed mashed potatoes works too!
- 1.6 oz sugar
- 1/2 cup warm water plus ~8 tsp later to reach desired consistency
- 1/2 tsp salt
- 1.5 tsp baking powder
- 4 oz dried mung beans
- 0.75 oz sugar (roughly 4 tsp)
- 1/4 tsp salt optional
- A dash of vanilla extract optional
- A neutral cooking oil for frying
Filling prep option 1 (Overnight, less effort)
- Rinse the mung beans under running water and drain, just like how you'd wash rice.
- Soak the mung beans option 1. Add enough hot water to go 1/2" beyond the level of mung beans, let it cool and transfer to the fridge overnight.
- Soak the mung beans option 2. Add enough hot water to go 1/2" beyond the level of mung beans, then drain when its no longer hot and replace with hot water twice over the course of two hours.
- Cook the mung beans. Using a steamer on medium heat is the easiest way to reach perfect doneness. You can also make it in a rice cooker with slightly more water than you would use to make rice, but you will lose some sticking to the pot. The beans are done when no longer crunchy, have softened and are ready to mash.
- Mash after it's cooked and add water to desired consistency. The goal is to have a paste similar to thick, slightly dry mashed potatoes.
Outer Shell (Vỏ)
- Mix 1/2 of the water in a big bowl. Add sugar, salt and mix to dissolve.
- Add remaining ingredients and mix (you can use a food processor if you want).
- The dough should be slightly dry and have a play-dough consistency. Rest 2-8 hours. It will be slightly rise and hydrate after resting, making it easier to work with.
Forming The Bánh Cam
- Flatten out a disk of the dough and add a ball of mung bean filling. The dough to filling ratio is up to you! I like about 1" in diameter, but you can make them bigger. Keep in mind they will slightly expand during cooking.
- Try not to leave any air pockets inside, since the dough will already be expanding and adding air to the center. Close off the ball so there aren't any cracks.
- Slightly roll in your hands to make a ball shape and then roll in a bowl of sesame seeds to coat thoroughly. Set aside for frying.
- Deep fry the bánh cam at around 285F. It should take about 11 minutes per batch. You may need to stir them a bit for an even fry.
