It has been proven that biscuits taste more biscuity when they are dunked in your favourite hot beverage, tea, coffee, cocoa, (maybe not bovril or that kind of drink!) apparently it releases more biscuit aromas. I think it makes them easier to eat too!
Some biscuits like ginger nuts don’t soften as much as ones like rich tea biscuits. The worst thing that can happen is that the biscuit/ cookie falls apart and bits fall into your drink. You can either fish the bits out with a spoon or wait till you have finished drinking and then scoop it out. Have a go if you haven’t dunked before… Enjoy!
