For me I am sure the most economical approach would be for me just to purchase chocolate. Back in the day I used to order a 5 lb block from Sears catalog each Christmas along with their 5 lb Masterpiece fruitcake. If I were to seek an online source for chocolate what should I look for and what would represent a good price?
Well, the bars I bought before I got my machine were 3 oz. Theo Organic Mint. They were $1.99 on sale / $2.49 regular for a long time before Obamaflation. Now they are $3.65 regular.
I just ran the numbers from my supplier for a straight up 100% Cacao bar... To make a 1KG batch is about 75% of a 3 LB bag of Cacao Nibs that are $21.99 on subscribe and save.
That comes out to $16.16 per 1KG batch
1KG is 35.27 Oz...
35.27 Oz / 3 Oz bar.. 11.75 Bars
That comes out to $1.37 Bar for 100%
I didn't add the required Cacao Butter because adding 50g of that drops the Cacao Nibs by 50g. It would probably be the same cost if not a miniscule difference, but the point is if I make enough, which I will, it will pay off the machine that costs $300 or $400 since I'm now saving approx. $2.28 per bar...
There's variables because I don't usually do the bars, I do the chunks of my recipe with cashews and raisins and dates etc... I'm just going off the straight up Cacao cost I would incur if I was buying 100% Bakers Chocolate or whatever separately. So, if I make 175 bars using said calculations, that pays for the $400 machine.
I think I'm probably half way there.
Whether you want to get into making it with a machine with the Nibs, or you just want to use Cacao Powder on the stove and mix it with Coconut Oil and a sweetener / Peanut Butter or whatever, the best source I have found is a family owned company called Terrasoul... They are great now, hopefully they won't sellout...
