uby Tandoh branded Matt Tebbutt a "git" in a row about lemon juice.
The former \'Great British Bake Off\' star - who appeared on the 2013 series - didn\'t take too kindly to the \'Saturday Kitchen\' host\'s playful jokes about his co-presenter Jack Monroe\'s love of bottled lemon juice on the BBC One cooking show.
She tweeted: "Why is Matt Tebbutt such a git.
"WHAT is the point in co-presenting a cooking show with @BootstrapCook for affordable and accessible recipes if you\'re gonna spend half the time ragging on bottled lemon juice and frozen spinach. honestly GROW UP. (sic)"
But the 46-year-old chef responded, defending his comments and asking if Ruby, 27, is "always" so cross.
He replied: "Wow! Are you always this angry? I didn\'t know about the vitamins in frozen spinach and the jif lemon juice was also a genuine question! (sic)"
Matt also suggested the baker should simply "watch something else" instead of tuning into his programme and getting wound up.
He added: "Can I suggest you watch something else rather than allow me to wind you up. ...life\'s too short ...which is more than apparent these days. (sic)"
However, Ruby wasn\'t letting the bitter lemon row end there, as she described his attitude as "flippant".
She wrote: "I was looking forward to seeing genuinely affordable and accessible food! i think you came off flippant.
"I\'m sure you didn\'t mean to but when the whole premise of the show is being flexible/cheap it matters if you\'re enthusiastic about the food or if you make it sound second-rate. (sic)"
