Same-day sourdough with a yeast boost
Mix at 9 AM and slice at 6 PM. A starter + pinch of instant yeast loaf for the day you forgot to feed the starter the night before.
Some Saturdays you wake up, look in the fridge, and realize you forgot to feed the starter Friday night. Instead of giving up on bread, give the dough a small assist: starter for flavor, a pinch of instant yeast for speed. The loaf is ready by dinner and tastes 95% as sourdough as the 36-hour version.
Why this works
Sourdough flavor comes mostly from the long ferment, but a healthy chunk also comes from the starter itself. A small amount of instant yeast (1 g) shortens bulk fermentation from 5 hours to 2 hours without overwhelming the starter character. The trade-off is a slightly tighter crumb — perfectly acceptable for sandwiches, toast, and last-minute dinner bread.

Common questions
Baker notes
- Use discard if your starter is sluggish — it still adds plenty of flavor.
- Don't double the yeast. 1 g is enough; more and you lose the sourdough character entirely.
- This is the loaf for unexpected guests, not the loaf for market.
FAQ
Can I sell this as 'sourdough' at market?
Technically no in most states — true sourdough labels require leavening from starter only. Sell it as 'artisan bread' or 'sourdough-style' to stay clean.

Keep this recipe in your back pocket for the days the starter loses. Even forgotten-feed mornings deserve fresh bread.
