Sorry to introduce a sour note, but have you noticed, McVitie's is making an abomination which they call "McVities Digestives Caramels".
You know how crunchy and moreish a choccy digestive is? well, the manufacturer has inserted an innovative new layer of caramel-flavoured kevlar between the chocolate and the biscuit, making the thing about as edible as Cure-C-Cure patch.
Avoid, people: avoid.
Note to United Biscuits: if it ain't broke, don't fix it...
