Sorry, but there's no substitute for yeast. If a recipe calls for instant yeast when you have fresh yeast (sold in blocks), use twice the as much. If a recipe calls for fresh yeast when you have instant yeast, use half the amount. You add the yeast to warm water with a little bit of sugar, stir it and wait until it rises. Make sure that the water's lukewarm (believe it's 105 to 110 degrees). Any colder and it won't work (also won't rise if you forget the sugar). If the water's over 115 degrees, then you've killed the yeast. After the yeast rises, add flour, salt, and any other ingredients.
