The Basics of Melting Chocolate

Whether you’re a professional baker or a chocolate enthusiast, understanding the science behind chocolate melting and tempering is essential for creating delectable treats. Melting chocolate involves raising its temperature to convert it from a solid to a liquid state. This can be done using various methods such as the double boiler method, microwave, or Bain-Marie technique.

Why Does Chocolate Melt?

Chocolate is made up of three main components: cocoa solids, cocoa butter, and sugar. Cocoa butter is a unique fat that has a melting point just below body temperature, around 93°F (34°C). This means that chocolate can melt in your mouth, giving it that smooth and creamy texture we all love.

The Tempering Process

Tempering is a crucial step in working with chocolate to achieve a glossy and stable finish. When chocolate is melted and cooled down, the cocoa butter can crystallize in different forms. There are six types of cocoa butter crystals, but only one is desirable for high-quality chocolate: the beta crystal.

During the tempering process, the chocolate is heated, cooled, and then gently reheated to encourage the formation of stable beta crystals. This ensures that the chocolate has a smooth texture, a shiny appearance, and a satisfying snap when broken. Tempered chocolate also has a longer shelf life and is less likely to develop a dull or grainy surface.

The Science Behind Tempering

Tempering relies on controlling the temperature of the chocolate to encourage the formation of beta crystals while keeping other unwanted crystal forms at bay. This is achieved by following a specific temperature curve. The three stages of tempering are:

  • Heating: The chocolate is heated to around 115°F (46°C) to melt all existing cocoa butter crystals.
  • Cooling: The chocolate is then cooled to around 82°F (28°C) to promote the formation of beta crystals.
  • Reheating: Lastly, the chocolate is gently reheated to around 88°F (31°C) to stabilize the beta crystals and melt any unstable crystals.
  • By precisely managing these temperatures, you can achieve perfectly tempered chocolate that is glossy, smooth, and has a desirable texture.

    The Importance of Tempering

    Tempering is crucial for a variety of chocolate applications, including coating, molding, and creating delicate decorations. Here’s why tempering is so important:

  • Appearance: Properly tempered chocolate has a glossy surface, making it visually appealing and enticing.
  • Texture: Tempered chocolate has a smooth and velvety texture, which enhances the overall eating experience.
  • Shelf Life: Un-tempered chocolate can develop a white, grainy surface known as “bloom” due to the separation of cocoa butter. Tempered chocolate has a longer shelf life and stays fresher for a longer period.
  • Melting Point: Tempered chocolate has a higher melting point, allowing it to maintain its shape and texture at room temperature, making it more suitable for decorations and coatings.
  • Troubleshooting Chocolate Tempering

    Tempering chocolate can be a delicate process, and things don’t always go as planned. Here are some common issues and their possible solutions:


    If your tempered chocolate develops a white, powdery surface, it’s likely experiencing bloom. Bloom can occur due to temperature fluctuations or improper cooling. To fix it, gently reheat the chocolate, ensuring not to exceed 88°F (31°C), and then cool it again following the tempering curve.


    If your chocolate becomes thick and lumpy when melting, it has seized. Seizing can happen if a tiny amount of water comes into contact with the chocolate. To salvage the seized chocolate, try adding a small amount of vegetable oil or cocoa butter and gently heat it until smooth.

    Dull Finish

    If your tempered chocolate lacks shine and has a dull appearance, it may not have been adequately heated during the tempering process. To achieve a glossy finish, ensure you are reaching the correct temperature during reheating and give the chocolate a good stir to encourage the formation of beta crystals.
