Pacaya volcano in Guatemala is already erupting since February, putting local people and authorities on red alert.

The streams of molten lava seeping down the hill, however, have become David Garcia's kitchen.

Garcia, a 34-year-old accountant, feeds visitors and locals alike "Pacaya Pizza" baked on the smoldering volcanic lava to astounded tourists.

"Many people nowadays come to experience the sensation of eating pizza prepared on volcanic heat," Garcia said from a rocky spot that connects to the Pacaya crater and serves as his job and he has turned it into his workplace.

Garcia places the dough on a metal tray that can withstand temperatures of up to 1,000 degrees Celsius in his improvised kitchen, then he rubs it with tomato sauce, a hearty serving of cheese, and bits of meat.

Garcia puts the pizza on the lava while wearing safety clothes from head to toe.

"It's cooked, just let the cheese melt some more," he declares 10 minutes later.

As the cheese bubbles, one of the visitor's comments, "That pizza looks amazing!"

As per AFP, Garcia's kitchen is becoming a fascination for visitors who build up an appetite hiking the enormous volcano — one of three active volcanoes in Guatemala — located just 25 kilometres south of the capital.

In 2013, he began making pizzas in little caverns he discovered amidst the boulders on the mountainside.

"I didn't sell enough the first several days," Garcia, whose popularity has already increased throughout social media, said.

With Pacaya constantly spewing out molten rock, he began cooking the pizzas right on the spreading lava, some of which has reached near to population areas in recent weeks.

Given the plumes of volcanic ash thrown into the sky by the furious beast, which some local people pray to, imploring with it to stop, it's a potentially hazardous effort.

"Eating a pizza baked in the blaze of a volcano is mind-blowing and uncommon in the entire world," Felipe Aldana, a tourist sampling one of Garcia's specialties, remarked.

He discovered the pizza parlor on Facebook and thought, "I must have this experience."

"It's insane simply thinking about eating food cooked on lava, but it's something you can witness only here in Guatemala," said Kelt Van Meurs, a Dutch visitor.
