Lisa Schroeder has been a chocoholic her entire life.

"I've loved M&Ms since I was a little girl so I've been destined to be a chocolate taster at Mars," Schroeder said in an interview with CNBC's "Power Lunch."

As a 15-year veteran at Mars Chocolate North America, Schroeder leads taste panels of 10 to 15 people.

"The things that we are looking for when we're tasting chocolate are the flavors of chocolate essence, caramelized sugar, we think about the texture and how it feels in the mouth and how it tastes," she said.

The taste panelists also do something else—they spit.

"When you are tasting candy all day long, you spit out because all good things in moderation… it's always a good idea to expectorate," Schroeder said.

So how does one become a chocolate taster? The first requirement is to love chocolate but that's just one criterion.

"You have to go through six months of training to learn how to evaluate chocolate and learn how to talk about its texture, its flavor, aromatics, how things smell, and we're also looking for people who know how to describe what they are experiencing," she said.

While Schroeder enjoys being in the office, her most exciting days on the job are not actually on the job. "When I see products that we have tasted and helped develop in panel like our Dove fruits…and you see those products and you know you had a part in bringing them to consumers for them to enjoy, that's really special," she said.

When asked if she could imagine doing anything else, Schroeder shook her head.

"I have the job that everybody wishes they had. So what could be better?"
