I found out about Bordier butter before my 2014 trip to Paris, and I sought it out as soon as I arrived. It’s not the easiest product to find, and it’s certainly among the more expensive butters on the French market, but it’s worth every minute and every penny it takes to get it on your plate. This video shows the manufacturing process, with emphasis on the “manu”; it’s all made by hand, and with a lot of love and respect for the process and ingredients. Fascinating video.
