How do you know if you need to temper your chocolate?
If you are using real chocolate (couverture chocolate that contains cocoa butter) you will need to go through the tempering process in order for your chocolate to harden properly.
Tempering is required any time chocolate contains cocoa butter (no matter how high or low quality that chocolate is), however it’s important to keep in mind that if you’re going to go through the work of tempering your chocolate you should definitely make sure you’re using a superior quality chocolate. When you engage in the art of tempering you should be rewarded with the best possible results!
The delicious alternative to tempering chocolateWhen using compound chocolate, often referred to as coating chocolate, you do not temper because compound chocolate does not contain cocoa butter. Compound chocolate is often associated with a less than desirable taste and some pretty nasty ingredients. If you’d like to skip the tempering and use a compound chocolate, you can say goodbye to the typical waxy cardboard flavor and toxic ingredients found in many mass market compound chocolates and coatings with Chocoley’s Bada Bing Bada Boom Gourmet Compound Chocolate.
Before you read further, please note that you DON’T temper chocolate when you are baking or are going to consume the chocolate immediately, such as melting and pouring over ice cream. We suggest that for the very best results in making candies and other dipped items, you temper the chocolate – even if it’s going to be used within 24 hours – especially if you want the chocolate to set up perfectly, to have a snap and a sheen, and if you want to coax the most flavor from the chocolate. If these details are not important to you, then you can use the chocolate without tempering if it will be consumed within 24 hours.
Now, about tempering…
If you are a mathematician or scientist, you’ll find the subject about tempering chocolate to be a simple concept. For the rest of us, the details are dull, boring, and sound a lot like mumbo jumbo or a bunch of nonsense. I made it all the way through college only taking one biology class, so its taken me a while to really grasp the concept of why the process of tempering produces the results that it does. To make matters even more complicated, every book, article or website I have researched about tempering chocolate has different methods or techniques for achieving this much desired “tempered state.”
The good news is, I am going to attempt to simplify and explain tempering so that you can understand it. If you are one of those mathematician or scientists mentioned above or already know this stuff, you can skip down to the methods of tempering below.
Okay, so what does tempering chocolate achieve?
When you temper chocolate, you’ll produce a finished product with a professional sheen, snap and taste – and your creations will not bloom when kept at the proper temperatures. Tempering is the process that re-establishes the cocoa butter crystals that are in real chocolate (versus compound chocolate). So, what on earth does re-establishing cocoa butter crystals mean? Let’s think about liquids becoming solids. When water turns into ice, most of us think this “happens” because of temperature. In part, that’s true, but what really happens is that when the water temperature drops to 32°F, water molecules come together to form crystals, and all of those crystals attach themselves together to form a solid mass – ice. Just think about the shape of a snow flake. A snow flake is an individual ice crystal.
Chocolate, not unlike the description of water/ice, starts as a solid (when you get your hands on it), then you melt it, turning it into a liquid. Ultimately, you want it to turn back into a solid (unless your using it in a fountain or fondue…then you can ignore this stuff!) to create wonderful chocolate candy, molded items, dipped items, etc. But unlike water turning to ice, where nobody cares how or why it happens, we need to be concerned with how to properly harden the chocolate so that it has the best sheen, snap and taste and so that it doesn’t bloom or separate.
Wikipedia.com (the free encyclopedia) explains how the cocoa butter in chocolate can crystallize in six different forms. The primary purpose of tempering is to assure that only the best form is present. Below is the Wikipedia.com chart showing the six different crystal forms and their different properties, followed by an excellent explanation of what the tempering process is actually trying to achieve.
Crystal Melting Temperature Notes
I 17°C (63°F) Soft, crumbly, melts too easily.
II 21°C (70°F) Soft, crumbly, melts too easily.
III 26°C (78°F) Firm, poor snap, melts too easily.
IV 28°C (82°F) Firm, good snap, melts too easily.
V 34°C (94°F) Glossy, firm, best snap, melts near body temperature (37°C).
VI 36°C (97°F) Hard, takes weeks to form.
For the best possible finished product, proper tempering is all about forming the most of the type V crystals. This will provide the best appearance and mouth-feel and creates the most stable crystals so the texture and appearance will not degrade over time. To accomplish this, the temperature is carefully manipulated during the crystallization.
The chocolate is first heated to melt all six forms of crystals (heat dark chocolate to 120°F, milk chocolate to 115°F, and white chocolate to 110°F). Then the chocolate is cooled to allow crystal types IV and V to form (VI takes too long to form) (cool dark chocolate to 82°F, milk chocolate to 80°F, and white chocolate to 78°F). At this temperature, the chocolate is agitated to create many small crystal “seeds” which will serve as the nuclei to create small crystals in the chocolate. The chocolate is then heated to eliminate any type IV crystals, leaving just the type V (heat dark chocolate to 90°F, milk chocolate to 86°F, and white chocolate to 82°F). After this point, any excessive heating of the chocolate will destroy the temper and this process will have to be repeated.
Working the melted chocolate on a heat-absorbing surface, such as a stone slab, until thickening indicates the presence of sufficient crystal “seeds”. The chocolate is then gently warmed to working temperature.
Stirring solid chocolate into melted chocolate to “inoculate” the liquid chocolate with crystals (this method uses the already formed crystal of the solid chocolate to “seed” the melted chocolate).
Thank you, Wikipedia, for the above valuable information, but let’s take it a bit further and define, step-by-step HOW to temper chocolate.
With the help from the good folks at baking911.com, here is their expert step by step instructions for three different methods of tempering (temperatures have been adjusted to reflect the best temperatures to work with Chocoley’s couverture and ultra couverture chocolates):
Traditionally, chocolate is tempered by pouring some of it on a tempering stone and worked into a “mush” as it cools. It results in the most glossy, crisp chocolate that will set with the most reliability and is recommended for the most demanding chocolate work. Before using, make sure the surface is a cold, clean and dry. If necessary, cool it by wiping with cold water and then dry it thoroughly, as tiny beads of water left on surface will cause the chocolate to seize.
Stir constantly during the steps and avoid having moisture from coming in direct contact with the chocolate:
IT IS NOW TEMPERED. A simple method of checking if the chocolate is in temper, is to apply a small quantity of chocolate to a piece of paper or to the point of a knife. If the chocolate has been correctly tempered it will harden evenly and show a good gloss within five minutes. Or, spread a thin layer on a scrap of parchment, wait five minutes, and then try to peel the chocolate from the paper. If you can, and it’s not blotchy, you’re in business. If not, start the tempering process again. KEEP CHOCOLATE IN TEMPER: Ideal temperatures are: Dark 88-90°F, Milk 86-88 degrees F, and white 82-84°F. If the chocolate hardens, you must start the tempering process again.
Thank you Baking911.com for your expertise in this area. Unfortunately, every expert has their own opinion of the proper method and techniques for tempering. While they all seem to be relatively similar, they often state completely different melting, cooling and reheating temperatures. The things that seem to remain constant, regardless of the expert opinion is:
