So I get down to Asda, and head up the breakfast cereals aisle, scanning the shopping list painstakingly prepared by Mrs O this morning.
Carrots (6) - check
Pot of bio-yoghurt - check
2 x Oatilicious loaves - check
Quark - ......... errr..... What?
What on earth is "quark"?
- a sub-atomic particle? What aisle is that in, computing equipment?
- a model of the Ferengi character from Star Trek: Deep Space 9?
- a refined Home Counties duck - ("quark, quark" rather than "quack, quack")?
Thankfully Mrs O is at hand, browsing the paperbacks in the Book aisle.
It's a sort of cheese, she says. And lo and behold, there it is, in the appropriate section.
So I think it's going to be quark on toast for an evening snack when we watch Wycliffe on ITV3 tonight ....
Have you ever heard of the stuff?
