"The most sophisticated of the galactic elite crave the most exotic delicacies and few come more exotic or delicious than diamond cheese. This cheese made only on a small agrarian world on the outer rim contains naturally occurring crystals and is so rare the top 1% wish they could afford it."
I want a cheese which has diamonds or some other crystals that form in it as part of the maturing process, in total it would be about 5-10 percent crystal by volume. These crystals must be like hard stones, harder than salt crystals. Hard enough to break your teeth.
The crystals can't be put in and the cheese can only be made using the kind of technology that was traditionally used to make cheese on earth. As a result putting the cheese under incredible pressure is out of the question, but using copper like for blue cheese is OK.
The cheese is made by milk from a regular cow. However as the cows are from another planet there is for them to have more of a particular chemical from food if it can act as a catalyst or something like that.
Some cheeses have crystalline structures such as Parmesan cheese crystals, but obviously these don't turn into actual stones.
It is possible that some sort of basic electrical generator could be used as part of the making process and this affects the structure of some sort of naturally occurring graphene molecules, but it seems unlikely these would turn into diamonds/Swarovski crystals etc.
It might be possible for cheese to be left for a very long time but then I don't know how to prevent the cheese from just rotting.
How do I get these diamonds in the cheese?
