I have several kilos of 100% Grenadian chocolate bars that are old. I enjoyed them when they were fresh but now they are dry and, although they still 'snap', somewhat crumbly. I would like to temper them and add cocoa butter to increase the creamy taste. Is there a limit to how much I can add? Will just tempering them restore to original consistency?

    I'm confused. You say 100% chocolate but you also say that you enjoyed them... In general, 100% chocolate is too bitter for eating out of hand as it has no sweetening (sugars). What do you mean by 100% chocolate? Can you post a link to the product or a photo of them?

    Edited out the "let the grand experiment begin!" at the end, because such mottos tend to have an insufferably foral scent to some here, which might downvote. Nov 12, 2017 at 22:56
  • @Catija I don't find it confusing. It is bitter, but people enjoy eating it nevertheless. So without any evidence to the contrary, I assume that the OP means exactly that, a chocolate bar made from 100% cocoa liquor, without any sugar added.

  • OP may meant “100% Granadian” chocolate-bars. Clarification would be warranted. Nov 13, 2017 at 0:36

Chocolate can age in different ways. The most common, and probably what happened to yours, is that it 'untempered' (blooming?). I believe simply melting in and properly tempering again will recover the brightness, texture, and flavor. If it doesn't, it might have oxidized and got rancid. This is very uncommon though since the cocoa fat is very stable and rich in antioxidants. It lasts more than two years usually.

Cocoa butter can surely be added to create a silkier and smoother texture. It is solid and stable at room temperature so in principle I don't see why there should be a limit. The science behind tempering is that of crystallization. Cocoa butter can crystallize in six different forms, each having very different physical properties (melting point, resistance to shear, etc). For this reason, it is good to keep in mind that the more butter you add, the trickier it can be to temper properly.

Personally, I find it easier to temper mixing with some already tempered chocolate, a method known as seeding. But in your case I don't know if it is worth it if this means mixing your 100% Grenadian (good stuff!) with some other commercial chocolate.

  • Yes, it is 100% chocolate and actually tastes quite sweet! I am quite sensitive to rancidity and it is not. There is a slight bloom on it. I will temper it once I get my molds in. Thanks one and all for your responses. Nov 13, 2017 at 18:52
