1 tsp instant yeast = 1 tsp baking powder + 1/2 tsp baking sodaChemical leavening agents that provide immediate rise without fermentation. Perfect for quick breads and when you don't have time for yeast rising.
Best for:
Chemical leavening, no rising time needed
Sourdough Starter
1/2 cup starter per 1 tsp instant yeastWild yeast and bacteria culture that provides natural leavening and tangy flavor. Requires longer rising time (4-8 hours) but adds complex flavor.
Best for:
Natural leavening, requires longer rising time
Self-Rising Flour
Replace all-purpose flour with self-rising flourFlour pre-mixed with baking powder and salt for instant leavening. No yeast needed, but results in different texture than yeast bread.
Best for:
Pre-mixed with leavening agents, no yeast needed
Beer
Replace liquid with room temperature beerBeer contains natural yeast that can provide leavening. Use room temperature beer and expect a longer rising time.
Best for:
Natural yeast from beer provides leavening
Rapid Rise Yeast
1:1Rapid rise yeast is very similar to instant yeast and can be used as a direct substitute. It has slightly larger granules but works the same way.
Best for:
Similar to instant yeast, can be used interchangeably
