🧀 Ever wonder what rennet is and how it works? Gather ‘round the cheese vat, folks. This tiny-but-mighty enzyme blend is what transforms milk into curds—essentially sending it on its whey to become cheese. 🐄 ➡️ 🧀 Let's dive curd-first into: 🔍 What rennet actually is 🌿 Where it comes from (animal, microbial, and plant-based sources) 🔬 The science of how it sets milk 🧰 What to do when curds don’t behave Whether you’re team animal rennet or riding with the microbial crew, understanding this

Rennet is the enzyme that turns milk into cheese. Without it, milk doesn’t coagulate and cheese can’t form. Traditionally, rennet came from calf stomachs and was used that way for centuries. I still use veal calf rennet in my cheesemaking. Today, most cheese made in the U.S. uses FPC (fermentation-produced chymosin) instead. FPC is made with CRSPR tech by inserting the gene that produces chymosin into microorganisms (like yeast or fungi). Those microbes are then fermented, and the enzyme is puri
