have had real U turn on the base dough
for those interested i will update spreadsheet added at the start of the post. there perhasps is not that much need as all anyone needs to know is amazingly here - a website i stumbled on called Forno Bravo.
http://www.fornobravo.com/#pizza_ovensseveral things conspired to force this re think.
firstly UB's "wet" - high hydration really does work for me - it produces far softer dough than otherwise possible. YES it's quite sticky and you do have to handle it differently.
i made a smaller amount of dough last weekend and picked up using the original spreadsheet values - i had not realised that i gradually upped the water amount to 65%. the cooked pizza dough was rubbish in comparison to what i normally make (using the revised hydration ie 65%).
the next day was Lucky enough to be in casa in liverpool - lovely dough. much much softer than i can produced. this got me thinking that i needed to use proper pizza dough. i got a bag of this "00" stuff (by mcdougalls) and have been putting the whole pizza base making through it's passes ever since.
anyhow in short water has to be 65% of the flour by weight. plain flour is still my preference. out goes the oil and the milk powder.
the forno bravo really does have all the info needed - even down to chucking the rolling pin out. the amount of salt they use is a tad high for me (i cut it by half).
