Digestives, Rich Tea, Ginger Nuts, Shorties and Custard Creams. Tend to dunk em all. I'm not a bit bothered about sludge in the bottom of my cup. Hobnobs need several dunks and tend not to leave sludge.
I do like the newfangled cookies too, and I do make them at home but they're not really dunk friendly.
Tim Tam biscuits (similar to Penguin ), are great with a brew. Bite off a bottom & top corner, hold the bottom corner in your coffee and suck your brew up through it like a straw.....Yum!!
