Introduction

PHOTO

Get ready to celebrate National Moldy Cheese Day on Oct. 9 and explore the tasty world of aged cheese! For centuries, cheese has been aged in order to bring out its flavors, textures and aromas. While some cheeses are only meant to be consumed fresh, others can be left for up to two years or more until they reach their peak flavor profile. On this day we honor these delicious cheeses that have been allowed time to develop a rind of mold on them - perfect for adding an extra layer of richness and complexity!

WHY THIS DAY MATTERS

Why We Love National Moldy Cheese Day

Moldy cheese is perfect for cooking

Moldy cheeses are amazing for adding depth and flavor to recipes like macaroni and cheese or pizza. The flavor of the mold will melt into whatever you're making, giving it a unique character no other ingredient can provide. They also add a powerful umami flavor which makes food more delicious!

Moldy cheese has a unique flavor

Moldy cheese is not your ordinary cheese - it has a distinct, earthy taste that can be surprisingly delicious. With its strong aroma and funkiness, moldy cheese packs a big flavor punch for only a small amount. Plus, because it's so pungent, you only need to use a little bit to give your dishes an intense flavor boost.

Moldy cheese has health benefits

Moldy cheeses are high in probiotics which can help the digestive system function properly, as well as support immunity and reduce inflammation. Eating these types of cheeses on a regular basis has been linked to improved skin health, increase in energy, and better overall health!
