We here report on the macro- and microscopic changes occurring
when sugar or fat levels of the sugar-snap cookie recipe are altered.
The macroscopic changes concern the dimensions of the baked cookies,
i.e. their diameter and height, their texture, i.e. the surface cracking
pattern, and their mechanical properties, i.e. break strength, whereas
the microscopic changes deal with the internal structure of the cookies.
Parameters used to describe the internal structure include porosity,
mean cell size, mean cell wall thickness and their distributions, and
the degree of an isotropy. Furthermore, the relationship between the
changes in these parameters and the varying mechanical properties,
i.e. cookie break strength, was studied.
