Tempering for chocolate is a process that has been shrouded in mystery for many years, with only a select few understanding the intricacies involved. However, with the rise of artisanal chocolatiers and home chocolate makers, the art of tempering has become more accessible and widely practiced. In this article, we will delve into the world of tempering for chocolate, exploring its history, science, and practical applications.
A Brief History of Tempering for Chocolate
Tempering for chocolate has its roots in the early days of chocolate production. The ancient Mesoamericans were known to have tempered chocolate, using a combination of heat and cooling to create a smooth, glossy finish. However, it wasn’t until the late 19th century that tempering became a widely accepted practice in the chocolate industry.
The development of the conching machine by Rudolf Lindt in 1879 revolutionized the chocolate-making process, allowing for the mass production of high-quality chocolate. However, it was the introduction of the tempering machine in the early 20th century that truly transformed the industry. This machine enabled chocolatiers to temper large quantities of chocolate quickly and efficiently, paving the way for the widespread production of tempered chocolate.
The Science Behind Tempering for Chocolate
Tempering for chocolate is a complex process that involves the manipulation of the crystal structure of cocoa butter. Cocoa butter is the main component of chocolate, making up around 30-40% of its total weight. It is a polymorphic substance, meaning that it can exist in multiple crystal forms.
There are six different crystal forms that cocoa butter can take, each with its own unique characteristics. The most desirable crystal form is the beta crystal, which is responsible for the smooth, glossy finish and snappy texture of tempered chocolate.
The tempering process involves heating and cooling the chocolate to create a stable crystal structure. This is achieved by heating the chocolate to around 105°F (40°C), which melts the crystals and creates a uniform liquid. The chocolate is then cooled to around 82°F (28°C), which allows the crystals to start forming again.
The key to tempering is to create a seed crystal that will guide the formation of the beta crystals. This is achieved by introducing a small amount of already-tempered chocolate into the melted chocolate. The seed crystal will then grow and multiply, creating a stable crystal structure that will give the chocolate its desired texture and appearance.

What is tempering in chocolate, and why is it important?
Tempering in chocolate is a process of heating and cooling chocolate to create a stable crystal structure that gives the chocolate a smooth, glossy appearance and a satisfying snap when broken. This process is crucial because it affects the texture, appearance, and overall quality of the chocolate. Tempered chocolate is more resistant to blooming, which is the formation of a white, chalky coating on the surface of the chocolate due to the migration of cocoa butter to the surface.
When chocolate is tempered correctly, it has a more appealing appearance and a better mouthfeel. Tempering also helps to create a more stable chocolate that can withstand changes in temperature and humidity, making it ideal for use in chocolate decorations, coatings, and other applications. In contrast, untempered chocolate can appear dull and streaky, and it may melt or become discolored when exposed to heat or moisture.
What are the different types of crystals in chocolate, and how do they affect tempering?
Chocolate contains six different types of crystals, each with its own unique characteristics and properties. The most desirable crystal form is the beta crystal, which is responsible for the smooth, glossy appearance and snappy texture of tempered chocolate. The other crystal forms, including alpha, gamma, delta, epsilon, and beta prime, are less desirable and can result in a dull, streaky, or soft texture.
The type of crystal that forms in chocolate depends on the temperature and cooling rate of the chocolate. To create beta crystals, the chocolate must be heated to a temperature of around 105°F (40°C) to melt all the crystals, and then cooled to around 82°F (28°C) to allow the beta crystals to form. If the chocolate is cooled too quickly or at too low a temperature, the less desirable crystal forms may predominate, resulting in a poorly tempered chocolate.
What is the ideal temperature range for tempering chocolate?
The ideal temperature range for tempering chocolate depends on the type of chocolate being used. For dark chocolate, the ideal temperature range is between 88°F (31°C) and 90°F (32°C), while for milk chocolate, the ideal temperature range is between 86°F (30°C) and 88°F (31°C). White chocolate, which does not contain any cocoa solids, has a slightly different tempering range, typically between 82°F (28°C) and 86°F (30°C).
It’s essential to note that the temperature range for tempering chocolate can vary depending on the specific chocolate being used and the desired texture and appearance. Some chocolatiers may prefer to work with a slightly higher or lower temperature range to achieve a specific effect. However, in general, the temperature ranges mentioned above are considered to be the ideal ranges for tempering chocolate.
How do I temper chocolate using the tabling method?
The tabling method is a traditional technique for tempering chocolate that involves pouring the melted chocolate onto a cool surface, such as a marble or granite countertop, and allowing it to cool and set. To temper chocolate using the tabling method, start by melting the chocolate to a temperature of around 105°F (40°C). Then, pour the melted chocolate onto the cool surface and allow it to cool to around 82°F (28°C). Use a spatula or offset spatula to spread the chocolate out into a thin layer and to break up any air pockets that may form.
As the chocolate cools, it will start to set and form a crystal structure. Use the spatula to scrape the chocolate back into a pile and to re-melt any chocolate that has set too quickly. Repeat this process several times, until the chocolate has reached the desired temperature and texture. Once the chocolate is tempered, it can be used for dipping, coating, or molding.
What is seeding, and how does it affect tempering?
Seeding is a technique used to introduce a small amount of already-tempered chocolate into a larger amount of melted chocolate to help initiate the tempering process. The tempered chocolate acts as a “seed” that helps to promote the formation of beta crystals in the melted chocolate. Seeding can be an effective way to temper chocolate, especially when working with large quantities or when the chocolate is particularly stubborn.
To seed chocolate, simply add a small amount of already-tempered chocolate to the melted chocolate and stir gently to combine. The tempered chocolate will help to initiate the tempering process, and the melted chocolate will begin to set and form a crystal structure. Seeding can be used in conjunction with other tempering techniques, such as tabling or machine tempering, to help achieve the desired texture and appearance.
How do I know if my chocolate is tempered correctly?
There are several ways to determine if your chocolate is tempered correctly. One of the most common methods is to perform a “temper test,” which involves dipping a small amount of the tempered chocolate into cold water and observing its behavior. If the chocolate is tempered correctly, it will set quickly and retain its shape, with a smooth, glossy appearance. If the chocolate is not tempered correctly, it may melt or become discolored when exposed to the cold water.
Another way to determine if your chocolate is tempered correctly is to observe its texture and appearance. Tempered chocolate should have a smooth, even texture and a satisfying snap when broken. If the chocolate appears dull, streaky, or soft, it may not be tempered correctly. Finally, you can also use a thermometer to check the temperature of the chocolate, which should be within the ideal range for the type of chocolate being used.
Can I temper chocolate in a machine, or do I need to do it by hand?
Yes, it is possible to temper chocolate in a machine, and many professional chocolatiers and chocolate manufacturers use machine tempering as part of their production process. Machine tempering involves using a specialized machine that heats and cools the chocolate to the ideal temperature range for tempering. The machine can be programmed to repeat the tempering cycle multiple times, ensuring that the chocolate is tempered consistently and accurately.
However, machine tempering is not always necessary, and many chocolatiers prefer to temper their chocolate by hand using techniques such as tabling or seeding. Hand tempering allows for more control over the tempering process and can result in a more nuanced and complex flavor profile. Additionally, hand tempering can be a more cost-effective option for small-scale chocolate production or for chocolatiers who are just starting out.
