How to Fix (And Prevent) Chocolate Bloom: 6 Tricks to Get Rid of That White Chalky Stuff on Your Chocolate Bars

Chocolate bloom, the white coating on chocolate, occurs due to temperature or humidity changes and comes in two types: fat and sugar bloom. Bloomed chocolate is safe to eat but may have altered texture. You can fix it by melting and tempering, and use it in recipes. To prevent bloom, store chocolate in a cool, dry place with stable temperature, avoid refrigeration, and keep it well-wrapped.

We all have those moments when we save our favorite chocolate bars for a special occasion or as a little treat, only to find them covered in a chalky white substance when we finally open them. Has our chocolate gone bad? Can we save it? Let's dive into the world of chocolate bloom to find out.

What is Chocolate Bloom and Why Does It Happen?

Chocolate bloom is the white, powdery coating that sometimes appears on the surface of chocolate. It comes in two main types: fat bloom and sugar bloom. Fat bloom occurs when the fat in the chocolate separates and rises to the surface, often due to improper storage or temperature changes. Sugar bloom, on the other hand, happens when moisture comes into contact with the chocolate, dissolving the sugar and then leaving a crystalline residue as it dries. Both types of bloom are caused by changes in temperature and humidity, which affect the structure and appearance of the chocolate.


Is Bloomed Chocolate Safe to Eat?

Yes, bloomed chocolate is safe to eat. The white coating may look unappetizing, but it doesn't mean the chocolate has gone bad. However, the texture and taste may be slightly altered. Fat bloom can make the chocolate feel grainy, while sugar bloom can create a gritty texture. Despite these changes, the chocolate remains edible and can still be enjoyed, although it might not be as smooth or creamy as when it was fresh.

How to Fix Chocolate Bloom: 2 Methods

Fortunately, bloomed chocolate can be fixed. Melting the chocolate can help restore its smooth texture. Here's how you can do it:

  • Break the chocolate into small pieces and melt it slowly using a double boiler or a microwave in short intervals, stirring frequently to ensure even melting.
  • If you want to achieve a glossy finish and snap, temper the chocolate. This involves heating and cooling the chocolate to specific temperatures to stabilize the cocoa butter crystals. Tempering can be done using the seeding method, where you add small pieces of un-melted chocolate to the melted chocolate to cool it down and encourage proper crystal formation.

Bloomed chocolate can also be safely used in recipes where appearance isn't as crucial, such as in brownies, cookies, or melted into sauces. The bloom won't affect the flavor in these applications, and the chocolate will still provide the desired richness and depth.


How to Prevent Chocolate From Blooming: 4 Tricks to Keep In Mind

To keep your chocolate as good as the day you bought it, proper storage is key. Here are some tips to prevent chocolate bloom:

  • Store chocolate in a cool, dry place with a stable temperature, ideally between 60-70°F (15-21°C). Avoid places with fluctuating temperatures, such as near ovens or windows.
  • Keep chocolate away from moisture. Store it in an airtight container to prevent sugar bloom caused by humidity.
  • Unless absolutely necessary, avoid storing chocolate in the refrigerator. The cold temperature and condensation when taken out can cause sugar bloom.
  • Ensure the chocolate is well-wrapped to protect it from environmental changes. Use the original packaging or an airtight container for best results.
