there’s a knack to pouring Guinness. doing it properly requires a double pour, and takes a couple of minutes to settle. the first 3/4 of the pour goes in to the glass at a 45 degree angle. then you set it aside while it settles — the Guinness cascade. it is wonderfully fascinating to watch. once the black stuff settles, the remainder is poured slowly until the head forms a slight dome over the top of the glass (or at least it should … i had a pint or two that didn’t quite suffice).
and despite being dark, a pint of Guinness has fewer calories than skim milk or orange juice. the Guinness diet works for me!
