Honey has only a fraction of the heat capacity that water has.  At 20C, only
about .54 compared to 4+.  Honey holds heat about the same as wood (Cp value
0.43). 

I don't understand the units Randy (or how water could have eight times the heat capacity of honey in any units.
From this site:
http://www.bee-hexagon.net/files/file/fileE/Honey/4PhysicalPropertiesHoney.pdf
(which is a really excellent reference, "The Book of Honey")
Thermal properties
For the design of honey processing plants its thermal properties have to be taken into account. The heat
absorbing capacity, i.e. specific heat, varies from 0.56 to 0.73 cal/g/0C according to its composition and state
of crystallisation. The thermal conductivity varies from 118 to 143 x 10-~ cal/cm2/sec/0C (White, 1975a).
One can therefore calculate the amount of heat, cooling and mixing necessary to treat a certain amount of
honey, i.e. before and after filtration or pasteurisation. The relatively low heat conductivity, combined with
high viscosity leads to rapid overheating from point-heat sources (see liquefaction)

So, from that reference, honey has 56 to 73 % of the thermal capacity of water (which is a nice 1 cal/g/degree
by definition in the rational metric system).
