Correct guesses will enter a draw for each of the mystery flavours in the What’s That Flavour? campaign and three lucky winners will walk away with a £50,000 prize each if they correctly identify them.
TV presenter and former England striker Gary Lineker, who stars in a supporting television advertisement, said he thinks he knows the correct three answers, but he is not allowed to enter the competition.
“It’s definitely not as easy as it sounds so I hope the nation has some fun testing their taste-buds,” he said.
The flavours will be revealed on 9 March.
