Active yeast, as if the fresh yeast and tiny particles are old. Yeast sold in food packages is preferred when preparing floury foods. With warm water or warm milk, the activation of the non-living is accelerated even more.
Saf Instant Yeast is one of the top selling yeasts worldwide. No need to "proof" or dissolve SAF; just add along with your other dry ingredients. Use in any recipe calling for active dry yeast: artisan loaves, pizza, sandwich bread, bagels, rolls, and more. No need to adjust the amount, use just as the recipe says.
