I bought this pastry at a restaurant today so I could photograph it. My wife gets to eat it tomorrow.
Setup
The tabletop is parchment paper that had been browned in the oven as if it had been used to make the pastry. A small continuous-light lamp is fitted with a diffusion sock slightly above the scene on the left side. Its diffusion sock and extremely close proximity to the subject create the softest possible shadows. A white reflector on the right side lifts the shadow tones on that side. A polarizer minimizes the glare and post-processing eliminates the remaining glare.
