Actually you're right, it was Robert Dyas - clearly considered more of a household product than a foodstuffIt's bloody lovely, been around a few months now, but it's availability seems to come and go. Robert Dyas, of all places, sell it! On the counter on the ground floor, £2.99 a bar or two for a fiver. It's the BESTEST choclit EVER.
It has great potential but it is rank. It's way too sweet and has a really horrible oily buttery aftertaste. I think it would work better with dark chocolate.
Actually I thought it was a bit too salty!! But agree probably better with dark chocolate old chap.
Was given a jar of Guinness-flavoured Marmite a year ago, they did a special run about 2008 and someone put a jar aside.
I can't stand Guinness but the Marmite with the flavour is delish.
