Cryostat

Remember the Seinfeld episode where Kramer gets a meat slicer and slices everything? I learnt to use the equivalent in the lab today. Although this one costs more than Seinfeld's Saab, the meat is... not edible, and slices are measured in microns. I am extremely tempted to section something edible though. I can do it while nobody's looking. Anyone care to suggest some food item, the size of a pea, and that may have interesting internal structure? I'll try to post an image if it works!
