This pig's bacon was delicious. But she’s alive and well.

I’m eating Dawn the Yorkshire pig and she’s quite tasty. But don’t worry. She’s doing perfectly fine, traipsing around a sanctuary in upstate New York. (Word is that she appreciates belly rubs and sunshine.) I’m in San Francisco, at an Italian joint just south of Golden Gate Park, enjoying meatballs and bacon not made of meat in the traditional sense but of plants mixed with “cultivated” pork fat. Dawn, you see, donated a small sample of fat, which a company called Mission Barns got to proliferate in devices called bioreactors by providing nutrients like carbohydrates, amino acids, and vitamins — essentially replicating the conditions in her body. Because so much of the flavor of pork and other meats comes from the animal’s fat, Mission Barns can create products like sausages and salami with plants but make them taste darn near like sausages and salami.

I’ve been struggling to describe the experience, because cultivated meat short-circuits my brain — my mouth thinks I’m eating a real pork meatball, but my brain knows that it’s fundamentally different and that Dawn (that’s her pictured above) didn’t have to die for it. This is the best I’ve come up with: It’s Diet Meat. Just as Diet Coke is an approximation of the real thing, so too are cultivated meatballs. They simply taste a bit less meaty, at least to my tongue. Which is understandable, as the only animal product in this food is the bioreactor-grown fat.

Cultivated pork is the newest entrant in the effort to rethink meat. For years, plant-based offerings have been mimicking burgers, chicken, and fish with ever-more convincing blends of proteins and fats. Mission Barns is one of a handful of startups taking the next step: growing real animal fat outside the animal, then marrying it with plants to create hybrids that look, cook, and taste more like what consumers have always eaten, easing the environmental and ethical costs of industrial livestock. The company says it’s starting with pork because it’s a large market and products like bacon are fat-rich, but its technology is “cell-agnostic,” meaning it could create beef and chicken, too.
