Let’s work through it

  1. To turn a 900 g dough formula into 1,350 g, divide 1,350 by 900 to get a factor of 1.5.
  2. Multiply every ingredient—including salt, starter and small additions—by 1.5. Round only after calculating.
  3. Check the sum of the new weights. Keep notes on rounding when a scale cannot measure fractions of a gram.
