Faster sourdough starter is for the impatient ones! This incredibly thorough guide will have you on your way to a healthy sourdough starter that's ready to bake with in just 24 hours.
In a large, non-metallic container, mix 100g unbleached all purpose flour, 100g room temperature water, and 1/2 teaspoon of active dry yeast until completely combined. No need to proof the yeast.
Either cover the container with a clean kitchen towel or transfer it to a glass or plastic container with at least 3 times the volume of the starter – it will grow! Do not seal airtight – your starter needs to breath.
Set the starter in a warm spot, free of temperature swings, and drafts to ferment for 24 hours.
Day 2:
After 24 hours, stir down the bubbles and transfer 50 g of starter to a clean starter jar and feed it by mixing in 50 g warm water until mostly combined, then add 50 g unbleached all purpose flour and stir until completely combined.You can save any amount of starter you’d like, but just remember it must be fed 1:1:1 ratio of starter:water:flour to keep your starter at 100% hydration. discard all but 50 g of starter and feed it with 50 g room temperature water and 50 g unbleached all purpose flour. If you notice a layer of liquid (hooch) on the bottom of the jar, stir this in before discarding.
Once the fed starter is fed, bubbly, and doubled in volume it's ready to use! This will take about 6-12 hours depending on your kitchen and starter.
Day 3 + Onward:
Transfer 50 g of starter to a clean starter jar and feed it by mixing in 50 g warm water until mostly combined, then add 50 g unbleached all purpose flour and stir until completely combined.You can save any amount of starter you’d like, but just remember it must be fed 1:1:1 ratio of starter:water:flour to keep your starter at 100% hydration.

Notes
Feeding + Storage
frequent bakerKeep your starter at room temperature in a NON-airtight container. To keep it alive, you'll need to feed it every 24 -36 hours, depending on the rate of fermentation. infrequent baker:Keep your starter in a loosely covered container in the fridge. To keep a refrigerated starter alive, it must be removed from the fridge, allowed to warm up slightly before feeding, then returned to the fridge. To bake with a refrigerated starter, remove the starter from the fridge 12 hours before baking, feed it as normal and allow it to activate before using.
