In using compressed yeast you may use double or even tripple the quantity of yeast given in your recipe in order to shorten time of fermentation.Be sure not to let your dough get too light at any stage of the procedure.

(In other words, don't let the dough go for too long a rise. If you use this procedure and watch your dough texture/height, there is no reason why this should not work, and want the joy of doing it yourself.)
