Because I am so new to the chocolate world, I am overwhelmed by the number of chocolates available for use. I am looking at the Qzina catalogue and I can see at a glance semi-sweet chocolate couverture in the following percentages of chocolate: 49, 52, 54, 55, 56, 57, 58 and 62. And this is only the dark chocolate, of course. Please don't tell me that it is just a matter of choice. Choice based on what? I can't afford to experiment with that many 5 kilo blocks, financially and time both at this point. I took classes with a professional chocolatier who uses Callebaut 815 at 57% , but the Qzina rep said I should use Callebaut 811 at 52%. I asked why, but he hasn't answered me yet. I've asked twice now. I am small potatoes or callets, I guess. I called the company and there is a 1$ difference in a 5 kilo block. Some one throw me a rope, please. A chocolate rope, I hope.
