There are so many ways to make chocolates. It depends on which form you gonna start making chocolates.
If it's from dark chocolate form, you will just use a double boilers method. But if you gonna do from raw cocoa nuts you will need Chocolate processing machines like chocolate melanger or food processor.
My suggestion: By processing Choco nuts into the chocolate melanger is the best way to make chocolates for home or commercial purposes.
This way, you will get nice, smooth, and buttery chocolate like a pro.
For this, you should buy good quality chocolate melangers or nut butter grinder like Premier Chocolate Melanger, Electra 11 Chocolate Melanger, Santha Chocolate Melanger, Spectra Chocolate Melanger, Spectra 11 Chocolate Melanger, Chocolate Melanger With Speed Controller, Electra 40 Cocoa Nut Butter Grinder with the controller, Electra 100 Cocoa Nut Butter Grinder with Controller, Santha Stylo Chocolate Melanger, and Santha 20 Chocolate Melanger with the controller.
There are even more chocolate making machines are available in the market. They effectively convert the whole chocolate beans into fine powder or a smoother buttery paste. Check this link chocolatemelangeur.com for much more chocolate making machines.
