The first step in tempering chocolate is heating the chocolate to 115°F (46°C) to melt all six forms of crystals. Chocolate scientists (what a job!) Please log in (or create a free account) to let us know how things went. It is the process of melting chocolate to a specific temperature to crystalize the fat in the cocoa butter. Chocolate is a combination of cacao, milk solids, sugar, and cocoa butter. The science behind nougat This website from the Exploratorium in San Francisco has information on various aspects of chocolate. The easiest way to temper chocolate is to use a tempering machine. During tempering, the cocoa butter in the chocolate takes on a stable crystalline form. Under‐tempering resulted in dissolution of a large number of small crystals, and rearrangement and recrystallization into a small number of larger fat crystals. Tempering the chocolate perfectly is the key to shiny, hard formed chocolate. Chocolate as we know it is made of cocoa solids, cocoa butter (fat), and flavourings/sweeteners. Or perhaps you want to coat some cake pops with it? Chocolate Tempering Method #1: The Stovetop or Microwave. I used a Kitchen Craft Digital Cooking Thermometer, which has a range of 0-200°C. Compared to a typical science class, please tell us how much you learned doing this project. Tempering is the process of precisely controlling the temperature of chocolate as it cools and hardens to achieve the best shine, color, snap, and texture. Stacks of various kinds of chocolate. It is the process of melting chocolate to a specific temperature to crystalize the fat in the cocoa butter. Unless you are a chef or have spent a few years at cooking school, you can be forgiven if you have no idea what tempering chocolate involves or why you would do it. The easiest way to temper chocolate is to use a tempering machine. Tempering Chocolate. Use care when working with hot chocolate. However, the temperature matters: heating chocolate only to around 63 degrees Fahrenheit (17 degrees Celsius) before cooling it results in a soft, crumbly product that melts easily. "Temper, Temper, Temper! The chocolate is now ready to be used for molding candies, coating, or dipping. The process of tempering chocolate involves three steps: heating the chocolate to to melt the fat crystals (all the crystals are destroyed), cooling the chocolate to bring the temperature down (new beta-crystals are formed), and then carefully reheating it again. When chocolate is in a solid brick form, the fat particles of the cocoa butter are in a crystalized hard form. For any other use, please contact Science Buddies. But behind the theatre, it’s all science. 2018-01-07. Cooling. Food Science: Why Temper Chocolate. This chocolate will have a dull, matt texture and a low melting point. Tempering Uncontrolled crystallization of cocoa butter typically results in crystals of varying size, some or … However, by heating your chocolate and then cooling it slowly to a specific temperature, you can ensure that your chocolate has a dense structure of beta crystals (that’s the fancy name for them) and a glossy, shiny finish that won’t melt when you touch it. When heat is applied, usually at 96ºF—the melting point for chocolate, which is a couple of degrees lower than body temperature (98ºF/37ºC)—the tempered crystals begin to detach from their bonds and disintegrate. Tempering chocolate consists of heating the chocolate to a certain temperature, cooling it to a certain temperature, and then heating it again to a certain temperature. Chocolate Science – Keeping your Temper. The Skill. Illustrated Tempering. Uncontrolled crystallization of cocoa butter typically results in crystals of varying size, some or all large enough to be clearly seen with the naked eye. Melt just until the chocolate is liquid and smooth (at 110°–115°F). Tempering chocolate consists of heating the chocolate to a certain temperature, cooling it to a certain temperature, and then heating it again to a certain temperature. Tempering Uncontrolled crystallization of cocoa butter typically results in crystals of varying size, some or … This video answers those questions and shows you how to temper chocolate using the seeding method. Day in and day out, I try and make chocolate making at home approachable. Step One. When tempering chocolate reaches 32.2 degrees Celsius, cool it down to 31.6 degrees Celsius by adding 28.35 g of the seeding chocolate. Tempering Chocolate. If the mass contains milk powder (which is often the case when making milk chocolate), heat will also encourage the Maillard reaction. How tempering chocolate hacks its crystalline structure. After the chocolate is fully set up, put them in the refrigerator 1/2 hour or longer, then unmold immediately. Tempering chocolate is a simple process that only requires a bit of time and a thermometer. Tempering the chocolate perfectly is the key to shiny, hard formed chocolate. If working with a microwave, heat the chocolate in short increments to avoid burning the chocolate. So, what on earth does re-establishing cocoa butter crystals mean? (n.d.). have discovered that there are six different stages of crystals depending on the temperature. It simplifies the science, eliminating any guesswork as it maintains the temperature for you. The key thing to know is that chocolate, like candy, is made up of crystals. Then you bring the temperature down to create uniform crystallization of the chocolate. Pour 80-85% of your chocolate onto your tempering surface. Tempering is a technique of controlled pre-crystallisation employed to induce the most stable solid form of cocoa butter, a polymorphic fat in finished chocolates. Make sure you keep the heat very low; if you use a pan, make sure it has a thick base. More in the Science Behind series: You can obtain each form by varying the fatty acid ratios and the temperature at which the chocolate is tempered (cooled). It is a science because the tempering is temperature dependent. Lemme get a little science-y for a minute. The complex science of tempering chocolate First, you’ll need to prepare utensils and ingredients that are ubiquitous in the kitchen: chocolates (any type – dark, semi-sweet, or white); a thermometer that can go as low as 80F, spatula, double boiler and cookie sheets/cutters or candy molds. And if you are all out of ideas for what to do with your beautifully tempered chocolate, check out Miss Hope’s Chocolate Box for some inspiration. Science Buddies Staff. The proportions required are normally around a quarter solid chocolate to three quarters melted chocolate. Tempering chocolate is the act of heating and cooling chocolate to specific temperatures to align fat molecules in cacao butter to the desired crystal structure (Form V) so that when it sets, the chocolate has desirable aesthetic properties and stable shelf-life.
