Chocolate and Water FAQ

Aside from wanting to know if there is a piece of equipment that can be used in lieu of the Melangers to refine chocolate, my most common question is about water and its place (or lack there of) in chocolate making. Usually this train of thought goes hand in hand with the Melanger question and goes something like this.

“If I use just a little bit of water, shouldn’t I be able to dissolve the sugar and mix it with the chocolate and then I don’t need the Melanger?”

Variations of this are “can I use honey, or agave syrup or something like that?”

My basic answer to these questions are “No, it just doesn’t quite work that way. If you add water to chocolate in general it will seize and you will end up with a thick fudge like chocolate product, but not really standard chocolate than can be tempered”. I have posed this question to a few other people just to make sure I was not missing something. So, here is a bit more of the specifics of why you really can’t add water to chocolate successfully.

If there was any practical way to get water into chocolate, it would be done commercially on a mass basis. Water is cheap and nutritionally perfect. Water in a chocolate system raises a lot of complex concerns:

1) Blending water and oil means you’re making an emulsion. This means the opacity of the chocolate and viscosity will be affected. Think about mayonnaise.

2) Cacao is a rich source of insoluble but water absorbent fibers (cellulose, primarily) which tends to cause the particles to draw in the water and swell up, further disrupting the texture. The cacao particles then tend to push away the cocoa butter.

3) Adding water means many new enzymes that were perhaps previously inactive due to lack of water can become active – remember, many enzymes work in non-aqueous systems with as little as 3-5% water. Adding a large amount of water (or water in the absence of sugar) could lead to issues with water activity and microbial concerns.

4) The presence of liquids will weaken or disrupt the tempering process and alter the texture of the cooled product. Depending on the amount and size of the water droplets, this can vary from making the chocolate softer to totally crumbly and impossible to temper to making ganache.

Adding emulsifiers can help blend the water with the oil better, keeping it in smaller particles. This helps reduce problems 2 and 4 a lot, but tends to cause an increase in the viscosity of the system, potentially worsening problem 1. For these purposes, lecithin is an alright emulsifier, PGPR works even better, and there are tons of there emulsifiers out there (mono & diglycerides, datem, etc. come to mind as solid water in oil emulsifiers). If you can add the liquid directly to the fat and emulsifier and blend agressively, sans cacao solids, it is better as you break the water up into smaller particles.

Using liquids that are mostly dissolved solids is also a good move, as they are slightly less lipophobic. This is where corn syrup, honey, etc. come in. The added viscosity also can tend to make the solution more stable, by interfering with surface tension and making it more difficult for droplets to re-agglomerate. Just think about trying tomix honey and butter versus water and butter.

But, bottom line, it IS possible to make a sort dark chocolate like substance using something like a thick agave syrup. You use a lot more cocoa butter and not too much agave syrup, and the end chocolate is softer and doesn’t develop a true temper/snap as you’d like… but it DOES work, and it sot of tempers. The same concept applies to any kind of similar syrup. The trick is careful incorporation, not using too much and understanding that the chocolate is going to be fundamentally different in nature. You also want to use plenty of lecithin here.

A few extra emulsifiers added could help yield a bit more stable product, but it’s not going to really perform any kind of magic. A few companies have been experimenting with ways to make 1 micron and lower sized micro-droplets of water into chocolate, but that water is entirely “locked away.” That means it is totally invisible in every way and offers no functional benefit except fat reduction. The commercialization is only starting on these technologies, and the cost may never be very low.

  1. Question about tempered chocolate using agave nectar sweetener.

    Hello John, I have been trying to figure out how to temper chocolate that has Agave as a sweetener. I went to a professional French pastry school where I learned how to make chocolate and when I ask them a question about using a liquid sweetener in chocolate and if it could then be tempered, they didn’t think it was possible. It appears that it is possible because of there are chocolate bars with agave which I have seen for sale online and they seem to be tempered. I haven’t contacted these companies because I doubt that they would give away their trade secrets, and would want me to buy their candy bars instead of making them myself, but I have my own ideas about the kind of chocolate that I want to make, which would be different than theirs. I have checked and there isn’t a crystallized form of Agave nectar. Might you know how I can temper chocolate sweetened with agave syrup and still have it come out being at a hard tempered state.

    I shouldn’t have sugar, which makes me ill, so I am trying to find an alternative that is healthy.

    Thanks very much for reading my e-mail, and if you don’t know the answer I’d appreciate it if you could lead me in the direction of somebody who you think does,

    Sincerely,

    Victoria Fuller

  2. Victoria,

    I have also seen these agave products and I don’t think they are actually tempered. To the best of my knowledge, there is no trade secret (then again, if it is secret, how would I know). They simply don’t bloom.

    I tend to agree with the assessment that you can’t temper with water present. It just doesn’t work. You might be able to use some of the suggestions above, and get a hard chocolate like product, but I am not sure just how worth the effort it is.

    I want to point out something that I hear a lot, and I think is worth thinking about. You don’t want ‘sugar’ because it makes you ill. Why I have to ask. ANY syrup has sugar. That is the definition of a syrup.

    Maybe you mean refined sugar. In that case, an organic unrefined sugar may be what you need. Just a thought.

  3. It could be that they used agave powder as any liquid/syrup can be spray dried to make a powder no ? Martin

  4. Hi Victor,
    I was wondering if you have had any success in figuring out how to temper chocolate sweetened with agave, as I’m on a similar mission myself! Any help would be greatly appreciated!

  5. hi Martin, there is a dried powder of agave but this is essentially inulin, which is not sweet at all.

    Hey Victoria: have you ever used coconut sugar? i find it amazingly healthy and very yummy…they also have it in a syrup form (a company called “coconut secret”).

    enjoy everyone!

  6. I found I can use dry Stevia powder and mix it into unsweetened chocolate and it works great. I make chocolate chips for snacking and also used it in a Chocolate meringue pie where I mix the filling with chocolate and whipped cream.

  7. hi
    this guy is saying :
    250 ML water
    90 Gr. dark chocolate
    i did not try iy
