This is why you should NEVER eat desserts from mason jars...

Mason jars are all the rage.

Whether it's as a crafty container to hold your breakfast or a fun and rustic way to serve cute desserts, it seems we can't get away from the glass vessels.

But the adorable mason jar you're using could land you in hospital.

According to the American Center for Home Food Preservation, baking bread or cakes in any canning jars that close with a canning lid "poses life threatening risks".

Why, you ask?

Because the ingredients in most dessert recipes can be low in acid, when the lid is sealed it creates the perfect environment for the growth of Clostridium botulinum bacteria. This can lead to botulism, a foodborne illness that can paralyse muscles.

Research has proven certain ingredients like fruit, zucchini, and water can make the risk of bacteria growth even higher.

However, the University Extension Food Specialists state that while you can see mason jar cakes in bakeries or stores, consumer products tend to go through safety tests, unlike DIY versions.

“When breads and cakes in jars are made for sale commercially by reputable companies, additives, preservatives and processing controls (that are) not available for home recipes are used. Safety tests would have been conducted for each specific recipe for commercial products,” they claim.

Looks like it may be time to kick the jars to the curb!
