Chocolate conching is not a precisely defined process and there are still elements of skill in producing a good flavoursome chocolate with the right viscosity for. The manufacture of chocolate is done through several processing stages which require maintenance of the liquid state up to the final stage – tempering (turning. The process of conching is unique to the chocolate industry and critical to the production of fine chocolate. Yet it remains an arcane mystery to.

Though he was initially distraught at the waste of energy and machine wear and tear, he quickly realized he had made a major breakthrough. Use a large, very sharp, straight-edged knife, cutting down with the full length of the blade, to cut the block into 24 bars.

In addition to the above basic instructions, there is also the Chocolate Melanger Instructions and tips which give a bit more detail on how to use and not abuse the Melanger.

Lindt’s original conche consisted of a granite roller and granite trough; such a configuration is now called a “long conche” and can take more than a day to process a tonne of chocolate. The temperature of the conche is controlled and varies for different types of chocolate. With modern equipment, there have been a number of conching advancements, notably high shear conches.

Refining and Conching

The name arises from the shape of the vessels initially used which resembled fonching shells. Allow to stand at room temperature until glaze is set.

The process of conching is unique to the chocolate industry and critical to the production of fine chocolate. Beat eggs with a fork until blended. Given that chocolate contains at least a few hundred flavor components, not all of which are known or understood well, he may have a point. And there are present-day manufacturers who have done away with the conching process altogether, substituting instead an emulsification process that uses a machine resembling an eggbeater.


Poole has an interesting background, one that includes working for the largest caterer in Slovenia as well as a stint as Pastry Chef on the American Orient Express, a luxury private train. Take the cover off for better heat transfer and so you don’t melt it. Rodolphe Lindt invented the “conche” in Berne, Switzerland in It is thought that one of the actions of this roller was to slowly grind the chocolate underneath it, completing the refining process.

Conching not only breaks down the particulate matter of cacao into bits so tiny your palate cannot detect them it also enrobes every little morsel in a perfect coating of cocoa butter. Remember that when we eat chocolate we are consuming the seed of a fruit. Under about 10 microns the chocolate can get gummy. All I can do is give you certain guidelines. That we have figured out how to make such a delicious treat out of them is one of the amazing parts of chocolate alchemy.

Meanwhile, place the shallow pan with the almonds in it into the heated oven.

The final liquid phase allows minor adjustment to the viscosity of the finished product by addition chocolste fats and emulsifiersdepending on the intended use of the chocolate. The power required to turn the conche shafts increases at this step. Immediately scatter miniature marshmallows all over the top of the brownie layer.

Conching and Refining — Chocolate Alchemy

But conching has its limits. There are numerous designs of conches. I turn mine off at night, put the bowl into a pre-heated oven about F, with the oven then turned off and let it set overnight. After the first hour though, the chocolate becomes more liquid like and the whole thing generates enough heat by friction that additional heat is not really needed. These solids are also very intensely flavoured with notes of bitter tannins, green vegetation, acetic acid and volatile elements which can taste like vinegar and nail polish remover.


Search for something else: This information was accurate when it was published. In the pasty phase more of the particles are coated with the fats from the cocoa.

Measure the marshmallows I use a 4 cup liquid measure for thatthen cover tightly with plastic wrap and let stand at room temperature until needed covering them prevents them from drying out. Oh, and I just saw they say it is “light weight” – don’t you believe them – this thing is a heavy duty monster – and that is choolate

Allow to stand on cooling rack until cooled completely. The process takes its name from conch shells, which the receptacles resembled in shape.

Remove to cooling rack, but leave oven on. There is no need to pre-grind your sugar. The early conches called longitudinal conches consisted of a granite roller that moved back and forth, pushing the chocolate in a trough. The three principles of vhocolate refining are heat, motion and time and a conching maching provides all three via a series of paddles or rotors which keep the chocolate molten and always moving over a heated base.

Finally, the bowl is held together my an epoxy that has a maximum temperature chocilate of about F.
