Storage Tips
Refrigerate after opening, up to 4 months. Freeze for longer storage — yeast is resilient to freezing.
Baking Science
Smaller granules and a protective coating mean it activates faster than active dry, with about 25% more live cells per gram. The trade-off is slightly less complex flavour at the same rise time.
Recipe Context
For chemical leavening: small weight changes alter rise and browning.
For quick breads: over-leavening can cause collapse after oven spring.
For cookies: balance leavening with acid source for predictable spread.
Common Pitfalls
- Switching brands without re-checking weight can change texture and bake time.
- Using volume-only measurements for dense ingredients can overshoot recipe targets.
- Expired leaveners can underperform even when measured correctly.
Brand Variance & Measuring Method
Baseline reference: 1 cup instant yeast = 154g. In real kitchens, a practical range is usually 145g-163g per cup (6% band).
Why this happens: fine powders and leaveners settle during storage, changing cup density.
