There are several types of dry yeast. Most often we see/use Active
Dry Yeast or Instant Yeast. Active dry yeast must be proofed in some
water before using. Instant yeast is added directly to the dry
ingredients without proofing. Instant yeast is much finer grained
than active dry yeast. You use less Instant Yeast than Active Dry
Yeast. You may use them interchangeably. For further information
check out either the Red Star Yeast or Fleischmann's Yeast sites.
