Split a sourdough build into its flour, water and starter parts.
The ratio relates the water and carried starter to a single unit of flour, so a 1:1:1 build is simple to scale. Feed ratio controls how acidic a starter turns; stiffer, larger-feeding styles keep it milder between bakes.
Sourdough Feeding Ratio
Feed hydration = water / flour; ratio = 1 : water/flour : starter/flour
