If you do any baking using yeast and haven’t tried this, you definitely should. SAF Red Instant Yeast can be used in any recipe in place of active dry yeast and it eliminates the need for proofing or dissolving. The substitution ratio is 1:1 so you don’t have to make any adjustments in measurements. It’s simply stirred into the dry ingredients of the recipe. I keep it in a canister in my refrigerator (for up to 6 months) and it has never failed me. And even if you only bake yeast recipes occasionally, it can be stored in your freezer for a year or more. Good stuff.
