They were enjoying burgers and cocktails when Molly began to play with the leftovers on her plate at the pub in Holloway Road.
Using the straw from her drink, she shaped the ketchup, mayonnaise, brown sauce and mustard to produce a copy of the classic work of art.
She also produced another portrait of her idol, Mexican artist Frida Kahlo, using leftover limes, tomatoes and lettuce leaves.
Molly, who studied at the Royal Drawing School for nearly 10 years, said: “It was just a whim – I was having fun with my friends in a pub and thought it would be funny for the waiters to see that when they came to collect the plates.”
Molly’s friends drew the attention of the chefs, who proceeded to take pictures of her artwork, which quickly gained notoriety and was picked up by the media..
The story of her food artwork was covered by The Sun, LADbible and an Indonesian website called detikfood, as well as featuring across social media.
She added: “Frida Kahlo is a face I’m very familiar with because I paint her a lot and I thought that would be a fun one for me. Frida Kahlo is definitely one of my favourite painters. I know that the Mona Lisa is such an icon and because Da Vinci is such an old master, I thought it would be funny if it were re-done out of ketchup.”
Molly was a Key Stage 4 student at CONEL where she won a seasonal greetings card competition in December 2015 and received an Excellence Award in 2016 for her achievements at the college.
At the time, she said: “I found all my teachers to be very qualified in their subjects and really enjoyed my lessons and coming into college every day. They gave me great one to one support when I was stuck and were absolutely brilliant. Overall, my time at CONEL was a fantastic experience.”
