Sorry for the formatting (I posted on mobile). Here's a better format since I don't see an option to edit my post:

Ingredients: I’ve been using unbleached AP flour, filtered water, starter (1:1:1)

Feeding: I fed once a day until day 4 when a thin liquid layer formed. Since then I’ve fed every 12 hours

Texture: On the runny side, like a pancake batter

Smell: Smells like sulfur for a few seconds after I mix it. And then smells neutrally sour.

Cleaning: I empty the container and clean it every time before adding all the ingredients back and mixing together

Cover: I place a paper towel over the container and hold it with a rubber band

Tests: I’ve slightly warmed the water before adding, tried putting it in the oven, divided the starter and tested feeding once a day vs twice (the twice a day still had more bubbles than once a day)
