Okay kiddo, so a Shropshire Bulla is actually a type of cheese that comes from a place called Shropshire in England.
Now, making cheese is a bit like making a cake. You need some special ingredients like milk, rennet (a kind of enzyme), and salt.
Once you have all your ingredients, you mix them together and let it sit for a while. This is where the magic happens! The rennet helps the milk turn into curds (the solid part of the cheese) and whey (the liquid part).
After a while, the curds are taken out of the whey and put into a mold. The mold helps the cheese keep its shape.
Finally, the cheese is aged for a few months to give it a delicious flavor.
So, a Shropshire Bulla is a type of cheese that comes from Shropshire, England. It's made with milk, rennet, and salt, and aged for a few months. Yum!
