Homemade waffle cones

I bought once some waffle cones from the supermarket in order to serve my ice-cream. First time, they served me well, but next time, my children asked only for the waffle cones to eat them as simple biscuits. I arrived in this way to buy them quite regularly. They were light, sweet and crunchy, no wonder that they were so much loved by my children.
That situation challenged me to make my own waffle cones. In fact they are just simple dry waffles rolled in a cone shape to hold the ice-cream.
With my dry waffle iron I baked the waffles. With a special wood cone, I rolled them up. I had to be very quick as they were drying very fast after removing them from the iron. But I learnt to make them very easily.
Guess what? They didn't arrive to be filled with ice-cream as they were eaten by my kids before. Now I need to do another batch....
