RGJ;
The only stupid question is the one not asked, so I don’t ever remember hearing any “stupid” questions.
When we make reference to dough absorption we are referring to the amount of water added to the dough. When expressed as a percent, such as 50% absorption the anount of water added to the dough is equal to 50% of the total flour weight, hence we always express the dough absorption as a percent of the total wheat flour weight. If there is any corn flour or other flour in the formula it is always shown as an added ingredient. The oil content, while performing in a manner similar to that of water, is not included in the dough absorption percentage. The oil is always shown as an added ingredient independant of the water. With this said, it should be remembered that oil (not shortening) will soften the dough in a manner similar to water, so if a dough is formulated with a high level of oil, say 5 to 8% you might to take that into account when determining what your dough absorption might be. Shortening, being a semi-plastic/solid does not exert this same effect upon the dough. As for yeast substitution, Fresh yeast/compressed yeast/brick yeast/crumbled yeast/wet yeast (they are all the same product) is replaced with ADY (active dry yeast) at 50% of the compressed yeast level and it is replaced with IDY (instant dry yeast at 0.4% of the compressed yeast level. Cracker type crusts are typically made with very low yeast levels (just like crackers are) and in some cases they might not even contain any yeast at all, but instead baking powder is used instead of the yeast at the same level. Some have referred to this as a Lavash type of crust. These, in my opinion, are probably best prepared as a parbaked crust and then dressed and final baked to the order. Because these crusts tend to be a bit short on flavor my favorite way to prepare this type of crust is to roll it in some sesame seeds when opening the dough into pizza skins, as the crust is baked, the sesame seeds are toasted giving the crust a great flavor.
