You start with a concept of what your what to have when you're finished. OK you don't have the sexy image in the cook-book, nor I suppose do you really and truly have the list of ingredients, nor quantities... but that's beside the point and only true pedants would point that out (right?), but I maintain: you start with a concept of what you will have by the end, and then it's more of an instinctive feel for what goes in, always tasting, adjusting the seasoning, the flavours, and you leave it to cook a while before adjusting again. Or it comes out burned. Spoiled. Inedible/unreadable.
Well yesterday, I made three very nice cup-cakes of poems for the portfolio. I say yesterday but in truth two of them had been working their way out for a week or so - and only yesterday did I actually have the patience and the time to focus - and hey, whaddyaknow, another popped out at the same time.
So, I think I've eight good poems now - 12 to go.
