4. What’s a coagulant?
A bacteria or enzyme that helps to change “liquid” cheese to a solid state
Originally found in plants
Butterworts, artichokes, etc.
Also found in the fourth stomach of “milk-fed” cows
In 16th Century Scotland, farmers would clean the fourth stomach carefully and hang it to dry for a day, then soak it in a salt solution and add it directly to cheese

5. Salt in cheese? Mmm…mmm…
Amount depends on type of cheese
Hard pressed:
Added to stop acid production from bacteria
Brine-salted cheese:
Cheese is added to a salt/water bath strong enough to float the cheese, causing it to absorb the salt
Soft cheese:
Helps add a rind to cheese

10. Cheese Racing
A game invented in the United Kingdom in answer to this question:
What happens when you throw a piece of individually wrapped cheese on a BBQ grill without removing the plastic?
The Answer:
The plastic apparently does not melt although the cheese does. The plastic wrapper inflates and finally pops, after the cheese inside has completely incinerated.
