Choosing ingredients for pizza dough is less about finding one universal ingredient and more about matching the fermentation method to your routine. Do you want a sourdough starter with a tangy direction, or packaged yeast that fits a more direct baking process? That choice affects pizza dough proofing, activation time, recipe support, and pantry format. This pizza flour, yeast & fermentation comparison separates the two sourdough starters from the two dry-yeast choices, then matches each to a practical use case.
Quick take
The main split is straightforward: Sally and Rebecca are sourdough starters, while Instant Self-Rising Dry Yeast and Active Dry Yeast are packaged dry formats. Sally brings a San Francisco identity and recipe files; Rebecca combines heritage wording with an activation guide. Instant Self-Rising Dry Yeast is the direct-mix route, while Active Dry Yeast is labeled for pizza and breads in an active-dry format. For a tangy sourdough direction, start with one of the first two; for less preparation before mixing, start with the instant yeast.

Product notes
San Francisco Sourdough Pizza Dough Yeast Starter, Sally

San Francisco Sourdough Pizza Dough Yeast Starter, Sally is a dried starter tied to San Francisco, with double pulverization for quick activation and 10 recipe files covering pizza dough, pretzels, sourdough bread, and more. Choose it when a named sourdough route and recipe support matter more than a packet-only workflow. The limitation is preparation: dried starter needs activation, so it does not match the direct-mix approach described for Instant Self-Rising Dry Yeast. It is a fermentation choice rather than pizza flour, making it suited to a dough project built around starter work.
Sourdough Pizza Starter Heritage San Francisco - Live 200+yrs Old

Sourdough Pizza Starter Heritage San Francisco - Live 200+yrs Old centers on Rebecca, described as a starter nurtured for over 200 years. It includes a step-by-step activation guide and recipes, and the product details call out sour flavor, tang, and big holes. Choose it for a guided heritage-starter experience with an explicitly San Francisco identity. Its limitation is the culture format: it is not a dry-yeast packet for direct mixing, so it suits a different workflow from Instant Self-Rising Dry Yeast. The live 200+yrs old wording is the defining point, not a flour specification.
Instant Self-Rising Dry Yeast - 12 Pack

Instant Self-Rising Dry Yeast - 12 Pack is the clearest fit for a direct-mix workflow. The fine granules can go straight into ingredients without pre-hydration, and the first rise can be skipped; pizza dough is one of the named uses. Choose it for quick preparation across pizza, bread, cake, bagel, and croissant projects. The limitation is the format and price: a 12-pack may not suit someone seeking a small trial, and it is the highest-priced choice in the comparison. It is therefore a dry-yeast pick, not a sourdough-starter pick.
Active Dry Yeast 3.5oz Italian Gluten-Free

Active Dry Yeast 3.5oz Italian Gluten-Free is aimed at baking pizza and breads, with a stated long shelf life, consistent performance, and fermentative power intended to endure. Its 3.5 oz item weight and gluten-free wording give the pantry format a clear shape. Choose it when active dry yeast fits your routine and those labeled details matter. The limitation is process matching: it is active dry rather than the instant format that goes straight into ingredients and skips the first rise. At $18.90, its 3.5 oz format also represents a different quantity choice from the 12-pack.
