A dear friend sent me a packet of confectionery eyeballs in the mail the other day.
I was seriously impressed by the detail in them: the difference in texture between the iris/lens/cornea etc (which is quite firm, even the shape of this part is quite accurate) and vitreous humour (which is slightly more squishy), and blood vessels. Clearly these guys have gone to a lot of effort to achieve anatomical accuracy while still keeping it a fun confectionery, which I totally respect. They taste great too: the vitreous humour has a very fluffy texture, very sweet, while the iris is firmer and very tangy, like lemon.
