In his role in "Burnt," Bradley Cooper plays a promising, albeit bad-boy chef. It's fitting, because outside-the-lines cooking runs in his family.

The actor, who's family is "in the garlic business," said he grew up cooking around his grandmother, a woman who made incredible pizzas, which "she cut with scissors."

"She was a very big, small woman with arms like Arnold Schwarzenegger," he told Jimmy Fallon on Thursday on "The Tonight Show." "She was like an Ewok with Schwarzenegger arms." He even said she had a unibrow.

Kimmel, for the record, said his grandma had "the first hipster mustache."

While he honed his inner grandma for the film, Cooper also consulted with several master chefs, including Gordon Ramsay. In doing the movie, he even came away with a better appreciation for one of the most sacred, simple kitchen utensils.

"I always thought a spoon was the most useless utensil ever," he said, "but you always want to have a spoon on you. Every chef has a spoon because you are tasting constantly."
