What Does Bread Made From 4,500-Year-Old Yeast Taste Like?

Turns out, pretty good.

Seamus Blackley is best known as one of the creators of the Xbox, but now he's putting his smarts to use elsewhere.

An Egyptologist and avid baker, Blackley recently wed his passions in a particularly unique way, baking bread from 4,500-year-old yeast meticulously extracted from ancient Egyptian ceramic pots.

"I'm a nerd," Blackley told Inside Edition with a laugh. 

His goal? To bake something that would closely resemble what the ancient Egyptians would have eaten. 

"These were formidable people," Blackley said. "They really loved food. There must have been something very special about their bread and we're trying to recapture it."

And for those of you worrying whether the bread is safe, Blackley has a message for you.

"When you bake something at 500 degrees for 40 minutes, nothing in it survives," said Blackley. "This is sterilized."

Inside Edition's Chief Correspondent Jim Moret visited Blackley in his kitchen to give the bread a try. 

"This is terrific," Moret said. "It's really good."
