## How to Convert Between Yeast Types ### Conversion Ratios **Fresh Yeast : Active Dry : Instant = 3 : 1.2 : 1** Or equivalently: - Active Dry = Fresh x 0.4 - Instant = Fresh x 0.33 - Fresh = Instant x 3 ### Notes One packet of active dry yeast is 7 g (2.25 tsp). One packet of instant yeast is also 7 g.
计算示例
A recipe calls for 21 g fresh yeast. Convert to active dry and instant.
- 01Active dry: 21 x 0.4 = 8.4 g (about 2.8 tsp).
- 02Instant: 21 x 0.33 = 6.93 g (about 2.3 tsp).
- 03Use slightly more than 1 packet of either dry yeast.
常见问题
Does active dry yeast need to be dissolved first?
Traditionally yes, in warm water (105-110 F). However, modern active dry yeast can often be mixed directly into dry ingredients.
Can I use instant yeast instead of active dry?
Yes, use about 25% less instant yeast than active dry. Instant yeast can be mixed directly into flour without proofing in water.
How do I know if yeast is still active?
Dissolve in warm water with a pinch of sugar. If it foams within 10 minutes, it is still active.
