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. Add Saf-instant yeast directly to the flour or at the start of the kneading process. Saf-levure should prior be reactivated by rehydration at a warm temperature. They all disperse easily and uniformly into the dough and gives optimum fermentation. Yeast is a living microorganism. This microscopic fungus is no larger than 6 to 8 thousands of a millimeter in size, yet has exceptional fermentation characteristics.
