ChefDaddy helped me with a recipe for English muffins. It requires fresh yeast. I assume this is the yeast my mother used to use that was in small cub

Yes, fresh yeast. Some say it taste better than active dry yeast and some say it's not true. Let yourself be the judge! I personally think it has a better outcome flavor wise. And yes, Moms who baked before active dry yeast was was popular used fresh yeast. Although, I hear it can be hard to find.
