Honey and sucrose are not the same chemically and do not perform the same within a dough. Honey is a monosaccharide (reducing sugar) that is composed of 38.5% fructose, 31% glucose, and maltose (7.2%), sucrose (about 1%) and higher saccharides. Sucrose, or ordinary granulated table sugar, is a polysachharide that has to cleaved into the reducing sugars fructose and glurcose. Fructose is about 1.6 times sweeter than sucrose, but yeast, which consumes only reducing sugars, prefers sucrose over fructose and ferments the sugars faster when using sucrose over fructose, as the experiment described at http://www.uni-regensburg.de/Fakultaeten/nat_Fak_IV/Organische_Chemie/Didaktik/Keusch/D-fermentation_sugar-e.htm
shows. As a whole, honey has about the same relative sweetness as sucrose (http://en.wikipedia.org/wiki/Honey
), and, according to our resident technical guru, November, honey can replace sucrose in a recipe on an equal weight basis, as he once explained to me in Reply 9 at http://www.pizzamaking.com/forum/index.php/topic,6372.msg54612/topicseen.html#msg54612
. However, honey has about 17% water (http://nutritiondata.self.com/facts/sweets/5568/2
), and, as a result, Freddy may want to lower the formula hydration to take into account the water content of the honey.
There are over 300 kinds of honey in the U.S., and they come in different colors and flavor profiles. The color will have an effect on the final crust coloration. Also, honeys can be raw and unprocessed or they can be processed and lack some of the enzymes of raw honey, which can affect the dough's performance. This subject is discussed in a series of posts at the PMQ Think Tank starting with the post at http://thinktank.pmq.com/viewtopic.php?f=6&t=4669&hilit=#p26883
Since Freddy is in Hawaii, which has some wonderful raw white honeys, my best advice to him is to conduct some simple experiments in which he swaps out the sugar in his dough formulation with raw honey. He will learn a lot from the exercise and he will remember things better than simply relying on what people tell him is the answer to his question. Freddy used the term "exactly" in his original question. His tests using honey will be as exact as he is likely to get in a non-scientific, non-laboratory setting.
