Wait what risotto?
I started raiding my Dad's whisky library when I realised that he had a range of different flavours, been doing some whisky cocktails -
we were right, the Old Fashioned was made weirdly at the cocktail bar at PAX, Using just a single big ice ball is useless for an Old Fashioned as the majority of preparation is stirring in a splash of blended whisky and a bit of ice at a time, the diluting, stirring and chilling effect is where the nuance lies with this drink.
On the other hand a shaken drink like a Penicillin really needs the big iceball or cube to serve with at the end. The great kick to this is putting a teaspoon of peaty whisky on top, that first sip destroys you with the ginger, honey, lemon and smoky whisky flavour.
One of the best for a hot day / afternoon / evening.
