The 9th of October is Mouldy Cheese Day.
It’s a celebration of cheese that’s supposed to have mould in or on it. Though sometimes, admittedly, it’s a challenge to know if you are supposed to eat the mouldy rind or not!
White mould cheeses such as brie and Camembert typically have a mild flavour, while green or blue mould cheeses such as gorgonzola or Stilton have a sharper, more pronounced flavour.
Did you know, there’s even a mouldy cheese related to the famous Maytag family? Yep, that’s right, Maytag Blue Cheese.
Some people not in-the-know think that today’s the day to root through your fridge for cheese that’s gone mouldy — and throw it out. Jokes aside, many people don’t know when it is and isn’t safe to just remove the mould from cheese that isn’t supposed to be mouldy, and eat the remaining cheese. We’ve listed some information resources below to help you find out.
So go grab your crackers and your chutneys to make up a cheese tray that can stand up to the more pronounced tastes of mouldy cheeses, and let’s celebrate them bringing such a range of flavours to our palates.
