What is the difference between brie & cambaret?
Size,
The make is identical.
To add, member Ben posted a good link here (https://cheeseforum.org/forum/index.php/topic,4031.0.html), also gives some history on both and on selecting ideal ones in store.
Essentially they are the same idea. Camembert is the Normandie version of the much older and more established Brie from Île-de-France. Brie is made in large short wheels and are usually too large for an individual to purchase and consume so they are mostly sold as wedges. Camembert is a small tall wheel (barrel shaped) and is sold in entire wheels.
To add to what Iratherfly has already explained they are from different regions of France and there is almost1,000 years between their creations. Camembert first came about when a farm girl hid a monk from the Île-de-France region who was fleeing the French revolution at the time, to repay her he taught her how to make the rind of the Camembert (as per his experience making Brie), until then it was just a farmers cottage cheese hence the difference in traditional shape.
Love these stories. Why can't I get one of these for my own cheese?
You will; just have to wait 1000 years!
