Beyonce's mother opens up about scary cooking accident

Tina Knowles is opening up about a scary cooking accident in her kitchen that left her needing a skin graft 20 years ago.

The mom-of-two, now 71, detailed the 2004 incident in her new memoir Matriarch, recalling that back then she was trying to keep up her mother's tradition of cooking large dinners every Sunday.

Tina was frying fish in a skillet while her husband at the time Mathew Knowles and stylist Ty Hunter were over in New York.

At the time she was on the phone with her pregnant daughter Solange, who was asking for instructions to cook chicken with a "cooking bag."

Upon hanging up the phone, Tina hit the sizzling skillet's handle, at which the contents splashed onto her.

The skillet fell off the stove towards Tina's stomach and pelvis, sending the "boiling lava" of oil down her left leg.

"The oil melted through the stretch of the jeans, then my skin, continuing down through my skin to the muscle," she recalled, being in so much pain she couldn't even scream.

Mathew, now 73, and Hunter were unable to hear her during the moment, because of which she couldn't get immediate help and stayed "trapped in the excruciating pain" with it reaching her bones. 

Eventually, Mathew found her and Hunter called 911. Tina lost the feeling in her fingers and was rushed to the hospital by EMTs. Doctors at the hospital informed the family that Tina's left leg would be smaller than her right.

Tina spent over a week in the hospital healing, undergoing a daily debridement (which removed dead and infected skin cells) before she was able to go in for her skin graft surgery.

She likened the debridement to being sent to "the torture chamber," where she experienced "showers of high-powered hoses held on the burnt skin to get the top layer off."

Tina recalled how her doctor "killed that surgery," moving skin from her hip to her thigh and grafting the wound.
