It seems that 84% sucrose solution in water has ior about 1.5 (whereas 
water is 1.33), so solid sugar might be around 1.5 to 1.56.

Now the problem might be the laminated sugar on sweets: you might have 
to model an opaque core within a surrounding sugar coating.  And here 
come the problem of coincident inner surface (not a problem, just no 
inner surface for the coating)

the coating might be about a millimetre deep. Remember to increase 
max_trace_level.

I wonder if the Subsurface scattering can be used to model that instead.
