My left over hunk of starter weights 463g after I have fed the starter and returned it to the container in the fridge. The question is how much flour and water is in the 463g of starter. I need to know this information before I can use it in any recipe. My starter has a hydration of 75% which means of the 463g there is 75% water compared to 100% flour.
The hydration of my starter my be different then your starter so you need to know what the hydration of your starter is. Many folks have a starter with equal amounts of water and flour which makes your starter hydration 100%. If that is the case you will take your amount of starter in grams and divide it by 2 instead of 1.75 like I do because my starter is at 75% hydration.
463g starter divided by 1.75 = 265g (flour in the starter)
463g starter minus 265g flour = 198g (water in the starter)
So now I know my piece of 463g of Desum Sourdough Starter has 265g of flour and 198g of water. What ever recipe I make I need to remember I have already 265g of flour and 198g of water. Just deduct those amounts from the flour and the liquid in the recipe and you are good.
