No, the dry yeast for pizza and savoury pies cannot be frozen. The live yeast contained in the package, that gives a delicious taste to your pizza, homemade bread, savoury pies or croissants, cannot survive freezing temperatures. Therefore, if you freeze, the rising action would be ineffective and you would not have the opportunity to appreciate the texture and delicious flavour that the yeast for pizza and savoury pies gives your recipes.
