it's a matter of teaspoons/gram conversion + dry/fresh and i've found conflicting info online.
cheers
would anyone have first hand experience of how to convert measurments of dry yeast to grams of fresh compressed yeast (what they sell in migros, coop).
Can't help with the conversion but, I know the coop (at least) sells dry yeast. It is normally where the flour and baking ingredients are. It is called Trockenhefe. I don't know if you are looking for that or not.
To convert recipes to use dry yeast, use 40% of the weight of fresh yeast - in other words, use 20 gr. dry yeast in place of 50 gr. fresh yeast (.4 X 50 gr.).
To convert recipes to use fresh yeast, divide the weight of dry yeast by 40% - so, use 100 gr. fresh yeast in place of 40 gr. dry yeast (.4/40 gr.). One other important factor is the liquid. Dry yeast must be dissolved in 4 times its weight of water. That means, if you are replacing 40 gr. of dry yeast, then reduce the water in the recipe by 160 gr.
Hope this helps...
