From bean to bar: Marou makes pure unadulterated chocolate

from bean to bar marou makes pure unadulterated chocolate marou1
After Samual Maruta and Vincent Mourou-Rochebois met in Vietnam in 2010, the two discovered they shared an interest in chocolate. “I told Sam wanted to check out the cacao farms in the countryside and he said, “Let’s do it” and pulled out his map,” recalls Mourou-Rochebois. The pair rode their motorbikes sixty miles from Ho Chi Minh City to the province of Bà Rịa–Vũng Tàu, where they spotted a sign for a cacao farm.

“When we approached it, we saw cacao beans drying out in the sun,” Mourou-Rochebois recalls. “We bought two kilos of beans from the farmer.” On their way back to Ho Chi Minh City, Maruta suggested they start a company. Mourou-Rochebois laughingly asked, “What, making chocolate?” And Maruta replied, “Why not?”

The duo opened their chocolate company Marou on the outskirts of Ho Chi Min City, selling their chocolate bars only in Vietnam for the first six month. Now Marou chocolate can be found around the world. “We’re the first artisanal, bean-to-bar company in Vietnam,” Maruta says. Both founders talked to  The Manual about their ‘Aha’ moment, Marou’s unique packaging and the importance of working directly with the cacao farmers in Vietnam.

When did you realize you could make your chocolate company come to fruition?

V: After our first test with cacao. We put the beans in the oven, took the skins off after roasting and made this thick mass. Then we stuck it in the fridge for 20 minutes, cut it up and tasted it. We looked at each other without saying anything and realized we had something. It wasn’t amazing chocolate but it had potential.

Where did you go from there?

V: in Vietnam, there are no machines for making chocolate and we realized we needed a certain machine to move forward: a wet grinder that a nearby Indian restaurant used for dosas, a dough made from lentil beans and chickpeas. We went to Singapore to get the machine and brought it back. That was a quantum leap in our chocolate making development. We could grind the beans down to something very fine–it started melting in the mouth. It started to look and feel like chocolate.

Did you run into any roadblocks when starting Marou?

S: For the first six months we worked out of my house. But we had big ideas and big plans.

V: We tried to get our business license and open up in the center of Ho Chi Minh City–a shop up front and a workshop in the back where people could see how it’s made. That was part of our dream. But the authorities wouldn’t allow us.  So we decided to go elsewhere and make chocolate and we found the place where we are now, on the fringe of the city. And it ended up being the right thing for us.

S: We’re growing. We’re taking on a hundred extra square meters to expand our factory. It’s satisfying to look back on how we’ve gone from nothing to something in just a little over two years.

Marou currently offers five chocolate bars–how are they each distinct?

V: The chocolate reflect each of the five provinces we work with. Each province has different soil configurations and micro-climates. Then the farmers add a touch as well. Just the way they handle the beans and dry them also affects the taste.

S: The most distinctive is the Bà Rịa, the red one. People who eat our chocolates say it’s special and unlike any other chocolate out there. And professional chocolate makers always order that one.

V: The soil there is very unique. It’s a red soil, so the chocolate has a little bit of a red tint. And it’s funny, it’s made with the beans from the first farmer we met. We’re still working with that farmer. We got lucky because he grows not only good beans but unique ones.

How many cacao farms do you work with and where are they located?

V: We work with about 10 farms. And the farmers have about  2 or 3 acres of land. Our closest farm is 60 miles from our factory.

S: We’ve ridden bicycles to our farmers–it’s that close. All of the farms are in provinces in the south of Vietnam. It’s tropical and hot all year round, which is the perfect condition for cocoa.

What are the reactions of the cacao farmers to your chocolate?

S: In the beginning, they looked at us in a funny way. The chocolate they know has a lot of sugar in it. So I think they believe we’re slightly deranged to like such bitter chocolate [laughing].

V: Also, other buyers in Vietnam don’t even taste or select their beans. They just buy bags and throw them onto a truck. But since we know that chocolate is only good as the beans, we spend a lot of times in the farms. Farmers present us with bags of about 50 to 70 pounds of beans, and then we sit and taste them. It’s time-consuming and they probably thought we were crazy at first. But now, they kind of get it. They understand what we’re looking for.

Your chocolates come in striking, vibrant wrappers–who designed them?

S: A company called Rice Creative, a two-man team who started their business the same time we were starting. We were their first clients so we stuck together.

V: It took about 7 months to get wrappers that reflected our brand identity and incorporated a sense of  place. We wanted to take people on journey as soon as they opened it. And the wrappers quickly got us a lot of attention. Distributors all over were curious enough to request samples. They told us: “If the chocolate is as nice as the wrapper, we’ll definitely buy from you.”

Lastlay, can you name all the ingredients in your chocolates?

S: Cacao and cane sugar. That’s it. There are no additives.

V: It’s really just about the cacao that we find from the farm. We don’t add vanilla, which is added to about 90% of dark chocolate on the market. In the beginning, we tested our chocolate with vanilla and realized we didn’t need it–our cacao is just good as it is.

Among Marou’s 12-member staff is Arnaud Normand, a chocolate maker who flew from France to learn about Marou’s bean-to-bar method. As Marou’s chocolate chef, Normand heads research and development for the company. Here’s his recipe for a flourless chocolate cake using Marou chocolate.

The 10 best canned sardines to elevate your summer cooking
Canned sardines are a great way to make a good recipe great

Luckily for sardines, bigger isn’t always better. These tiny but mighty fish are packed with nutritional goodness and full of complex flavor. Unlike anchovies, their teeny counterparts, sardines have a far milder, rounder, less "fishy" flavor. Briny and complex, these little guys pack a delicious punch of salty, savory bite when used in a dish properly. The best canned sardines are even incredible alone, or when simply topped on toast, served with lemon and fresh herbs.

Additionally, sardines in a can are a sustainable source of protein for pescatarians, keto fans, and foodies looking for a punchy new ingredient. They’re rich in calcium, iron, vitamins, and omega-3 fatty acids. But, unlike larger species, sardines don’t contain high levels of contaminants like mercury that could compromise your health.

The 10 best recipe apps to channel your inner chef
Looking for a great home-cooked meal? Download these recipe apps, and you'll be cooking it up in no time
Man using smartphone while preparing food in the kitchen

We now spend a lot of time on our cell phones searching for recipes. Our new normal has led us to get in touch with our inner chefs. We also learned that searching for recipes via the web on your mobile device can be a laborious task in and of itself. And nine times out of 10, when you find a recipe that looks good, you're directed to a food blog where you have to scroll through pages of the author's story about the dish's history, where they got the ingredients, what the food means to them, and other SEO filler. Not to mention the pop-up ads!

If you haven't realized it by now, this is where recipe apps come in very handy. In some instances, you'll have to endure ads (mostly in free apps), but in most cases, recipe apps are direct and to the point. They take you to the recipe, with a clear list of ingredients and how to prepare them. They have a photo with the finished product (which you hope you can match), and that's it. Some apps even have set-by-set video instructions to walk you through the cooking process. Unlike food blogs, you can choose to click on additional content. Plus, depending on the app, they have many other valuable features. Some apps are dedicated to your dietary restrictions (plant-based/vegan, keto, etc.).

Friends playing drinking card game

Everyone loves a good drinking game, this much is true. The very best of them tend to be drinking card games. Makes sense, who wouldn't want to revisit those old college memories of playing King's Cup? Or learn a new game by gathering (safely) with friends to play a drinking card game or two? With a bit of ingenuity, some of these games could even be played virtually; for example, you could designate a dealer in each house to make sure all the cards line up and are the same for each player. Sure, it's a little more complicated, but a good game with your buddies is worth it.

We've got the rules for some of our favorite drinking card games, below, along with some more elaborate ones you can buy online. Cheers!
