Vietnamese Corn Milk Recipe (Sua Bap)

The name - corn milk, may sound odd. Is it a typo? What is it? Corn milk - often called sữa bắp in Vietnam, is a creamy, refreshing, and slightly sweet beverage. It is incredibly tasty for something that employs just a handful of readily available ingredients (mostly corn and water!).

Sữa bắp is an enticing refresher that I’ve enjoyed in Vietnam and abroad. You may have spotted sữa bắp at casual joints, delis, and bakeries. I first noticed a sign for it at a tiny pho shop in Hanoi's Old Quarter. Corn milk and pho? Why not?

As with a lot of Vietnamese foods, corn milk is flexible. It can be vegan (or not), but it is definitely not a dairy substitute. Most Vietnamese language sữa bắp recipes call for using ‘American corn’ and praise it for good flavor, handsome color, and healthful benefits. They also include evaporated milk and sweetened condensed milk (SCM) for creamy sweetness.

With a bounty of sweet summertime corn in the States, I combine our maize with a touch of coconut milk (it’s a classic Viet pairing that’s dairy free too). Natural corn starches and sugars create a smooth, delicate sweet beverage; vanilla adds dimension. No sweetener is needed, though you could add SCM, if you like. There’s corn flavor in the silk, tender husks, and cobs so they are part of the cooking phase to create a drink that screams, “I’m corny!”

I'm sharing the corn milk recipe from my new book, Ever-Green Vietnamese, because I don't want you to miss out. We couldn’t photograph every recipe for the book and I don’t want you to overlook this gem.

Options for enjoying corn milk

Corn milk is usually served as is, with or without ice. But you could be offered as a light soup. Ever-Green Vietnamese recipe testers Nathan and Kate Schmidt added dark rum to create a cocktail. I've frozen it for ice pops too (see below).

Corn Milk Variations

Want an extra tropical take? Caroline (@carolinesaigon on Instagram), a Vietnam-based chef, recently told me that folks there are nowadays adding pandan juice to corn milk. The pandan leaves add a tropical grassy note and green hue. I tried it with frozen pandan leave and used a little too much so the resulting pandan corn milk tasted somewhat soapy. Pandan can overwhelm. But it was fragrant and handsome. In my recipe Note below, I offer you a range so you can choose.

Frozen pandan (lá dứa) for its availability at many Southeast Asian and Chinese markets. Sometimes it's available fresh. What is rozen mostly comes from Vietnam.

Can you use pandan extract? It's very convenient but the green co]or is very aggressive. It can color things Incredible Hulk-like green before there's enough pandan flavor. On the left, I used a toothpick tip's worth to color ¼ tsp of water. Dispense the extract gradually and with care.

Corn Milk Video Tips!

Bonus idea: Popsicles

When I make too much corn milk or just want a different way to experience it, I turn it into popsicles. You simply pour it into molds and freeze overnight. Here's a combo of corn, pandan, and even ones that combine pandan and corn. I use silicone popsicle molds for easy removal.

While corn is still in season, make sữa bắp!
