[MUSIC] >> My name is Robyn Sue Fisher. And I'm the founder and chief ice cream maker at Smitten Ice Cream. Started off, actually, at the GSB when I dove into entrepreneurship. And took a bunch of classes in that space and decided to focus on something I loved and was passionate about, and that was ice cream. My goal was to take a product I love an... Read More
Key Insights
- Liquid nitrogen is negative 321 degrees Fahrenheit, allowing the ice cream mixture to freeze extremely cold and quickly. Fisher connected this temperature to smaller ice crystal formation, which could create a smoother texture while making individual servings to order.
- The Brrr machine emerged from two years of repeated experimentation in a basement shop. Fisher and an engineer tested different mixing devices until they produced the prototype of the machine later used to make ice cream at Smitten Ice Cream.
- The Brrr machine uses a double-helical mixer that scrapes its surfaces as it operates. This mechanical design helps create exceptionally small ice crystals, supporting the smooth texture that Fisher identified as central to improving the finished product.
- The machine's proprietary software controls viscosity and dosing while providing real-time feedback. It is designed to recognize when it has produced the desired scoop and then stop automatically, combining freezing science, mechanical mixing, and software control.
- Street selling provided a direct test of whether customers wanted the product. Fisher spent nine months serving ice cream in San Francisco streets, alleys, and parks before growing lines and daily sellouts generated enough momentum for a permanent shop.
- The first Smitten Ice Cream shop was constructed from a 40-foot recycled shipping container cut in half. One section became a small kitchen, while the other became an open retail bar where customers could watch four Brrr machines operate.
- A small menu allows Smitten Ice Cream to concentrate on doing one thing as well as possible. Fisher says this focus makes it possible to select the best ingredients and work toward making every flavor as perfect as the team can.
- Love for the work sustained Fisher through several years without significant success. Her entrepreneurial advice is to pursue something personally meaningful rather than merely a business idea, because genuine commitment helped her continue until success began in year four.

Questions & Answers
Q: How does liquid nitrogen make ice cream smoother?
Liquid nitrogen freezes the ice cream mixture at negative 321 degrees Fahrenheit. Fisher explains that colder freezing can produce smaller ice crystals, and smaller crystals can create a smoother texture. The extreme cold also makes it possible to prepare ice cream to order. At Smitten Ice Cream, this freezing method works together with specialized mixing equipment to produce each scoop.
Q: How did Robyn Sue Fisher develop the Brrr machine?
Fisher began experimenting with liquid nitrogen while attending Stanford Graduate School of Business, even sourcing a tank and making ice cream in her backyard. After school, she spent two years in a basement shop with an engineer, repeatedly making ice cream and testing different mixing devices. Their work eventually produced the prototype of the Brrr machine used at Smitten Ice Cream.
Q: What does the Brrr ice cream machine do?
The Brrr machine freezes fresh ice cream with liquid nitrogen while a double-helical mixer scrapes its surfaces to help create exceptionally small ice crystals. Proprietary software controls viscosity and dosing and gives real-time feedback during production. The machine recognizes when it has created the desired scoop and stops automatically, while customers can watch the process and surrounding nitrogen vapor.
Q: How did street selling help launch Smitten Ice Cream?
Fisher used a Radio Flyer wagon to carry a 40-pound stainless steel device and a tank of liquid nitrogen. For nine months, she sold ice cream in streets, alleys, and parks around San Francisco. The experiment let her determine whether the concept would work. Eventually, the business attracted repeated lines, sold out every day, and gained enough momentum to open its first shop.
Q: What is unusual about the first Smitten Ice Cream shop?
The Hayes Valley shop is built from a 40-foot recycled shipping container that was cut in half. One half serves as a tiny kitchen, and the other functions as an open retail bar. Four Brrr machines sit along the front bar, allowing customers to interact with the experience and watch their own ice cream being made in front of them.
Q: Why does Smitten Ice Cream keep its menu small?
Fisher believes it is extremely difficult to do two things better than anyone else, so the business concentrates on one product and tries to make it as well as possible. A small menu supports that focus by allowing the team to select the best ingredients and devote attention to making every flavor as close to perfect as it can be.
Q: Why did Robyn Sue Fisher choose ice cream as her business?
Fisher wanted to pursue something she loved and improve a product that already mattered to her. Ice cream had brought her family together and created delightful moments in the day. After working in consulting with biotech, health care, and large companies, she also wanted work that felt more personal and produced a direct human reaction from customers.
Q: What entrepreneurial advice does Robyn Sue Fisher give?
Fisher advises entrepreneurs to pursue something they love, not merely a business idea. She says she did not experience real success until year four and doubts she could have continued without caring deeply about the work. Her experience suggests that personal commitment can provide the persistence needed through experimentation, uncertain demand, street selling, and the long period before a business gains momentum.
