NASA grows green chiles in space, but it hasn’t figured out how to roast them

Open flames are a no-no on the International Space Station

Green chile is in space, but it will take more time for science to catch up to roasting the pepper so it can give its best-quality taste.

“We only have a warming oven onboard that goes to about 180 degrees Fahrenheit, so we could make them warm, but we couldn’t really roast them. So we elected to just eat them raw,” NASA astronaut Megan McArthur said in an interview with Source NM and other outlets from space. “We all tasted them both, the red and the green. And they have a nice spiciness to them, a little bit of a lingering burn. Some found that more troublesome than others.”

This week NASA’s SpaceX Crew-2 astronauts had a taco party complete with space-grown chile, using the seeds of an Española Valley variety. A celebratory moment for space science and the residents of Earth from the chile mothership in New Mexico.

But as McArthur admitted live from the space station, the chile was not roasted, and as every quality New Mexican knows, these peppers must be cooked and peeled before eating.

Take it from the New Mexico State University Chile Pepper Institute:

“The most important step in processing green chile is removing the outer skin, which is necessary before further cooking or canning,” according to the experts. “Be sure the heat source is very hot. Turn chiles frequently to prevent scorching and ensure even blistering. Once the skins are evenly blistered, remove chiles from heat and spread out on a flat surface in a single layer to cool before peeling.”

(And wear gardening gloves or something when you do it. And don’t rub your eyes until you wash your hands a bunch. It can get pretty bad.)

Of course, this all changes in space, where open flames are not to be introduced.

NASA scientists said they did have a microwave on the ISS that could reach temperatures at about 180 degrees. Sadly, that’s well below the threshold to ignite the capsaicin in the peppers that activate the best flavor, let alone shed the skin for tastier consumption.

Experts at NMSU suggest peppers should be cooked at a temperature of at least 450 degrees.

Despite the rawness of their chile, astronauts on the ISS said they enjoyed their taco meal with the space spice.

“We did all enjoy them. And the tacos were very tasty. It’s really nice to have something that smells so fresh, and then has the nice crunch of a fresh vegetable as well,” McArthur said. “So it was a real treat for us.”

The NASA astronauts will return to earth early next week. However the toilet on their ship back home is not working.

(NASA would not confirm if that malfunction had anything to do with the green chile.)

Maybe someone can bust out some roasting drums on the landing pad so the astronauts can be greeted with that smell wafting around New Mexico from farm stands and grocery store parking lots when the year’s harvest comes in.
