Increase hydration in a no-knead sourdough bread
I have the food52 no-Knead sourdough bread recipe, and the reviewer said they increased the hydration by 25% and added malt. I have the malt but am new to this and don't know how to increase the hydration by 25%. 480 grams flour, 100 grams sourdough starter; I put the same amounts of starter, flour, and water in mine daily. And 303 grams of water. Any help would be greatly appreciated.
