The dissociation of a preparation


The dissociation of a preparation
It may have already happened to you: You prepare a sauce, a cream, a ganache etc. and then suddenly or almost, the whole thing dissociates, and from a smooth mixture that you were preparing with love, you end up with a horrible thing with a more or less solid part and another liquid part.

It's the dissociation, or as the french pastry chefs and cooks say, "it's tranché!".

The dissociation of a preparation
For example, here is a chocolate-hazelnut ganache that is tranché:

ganache qui a tranché


It doesn't show up very well in the (small) photo, but there's a thick chocolate-hazelnut pan base, and on top a layer of liquid fat.

What happened?


In the vast majority of cases, it's because in your mixture there is a fatty part and a watery part, the whole thing comes together in a delicate balance.
If this balance is broken because there is too much of one or the other, or a thermal shock, the whole which was homogeneous dissociates, it cuts!

This imbalance is often caused by the heating, perhaps excessive, of the preparation, and during this heating the water can evaporate and reduce, the fat not.
This is what happened with the ganache above, I didn't remove the simmering cream from the heat soon enough before adding the chocolate and hazelnut powder, sad result.
Another example, a bearnaise sauce or a hollandaise sauce that slices when it was almost finished, it's certainly because there was too much butter added and not enough water in the vinegar-wine-herb or lemon reduction.

And besides, it doesn't prevent this tragedy, there is little or no warning of disaster for an amateur, it is quite brutal.

What to do if it does?


1) Don't panic, don't despair, because it's very easy in this situation, so great is the disappointment, to swear a good big blow, to say to oneself that it's ruined, and to throw everything away...
2) Keep a critical eye: OK it's tranché, but what if it lacks water? Let's try to compensate it, and for that :

- Remove immediately from the heat or the water bath
- Add, very cold, a little bit of water (Béarnaise) or one of the components that brings it (cream for the ganache).
- Take the mixture back slowly, with a whisk, a spatula or a maryse to incorporate this addition (cross your fingers too, put all the chances on your side ;-).

3) If it still doesn't work, use the super power of cornstarch:

- Incorporate a mixture made of a tablespoon of water and a teaspoon of cornstarch in the preparation that you will put back on the fire and will whip until return of the initial texture.

eau + maïzena



You will have understood, there is no fatality in these small culinary dramas, it is just a bit of physics in your pan, it is necessary to try to be attentive enough during your preparation, to prevent rather than to cure.

To sum up: A preparation that goes off is most of the time an imbalance of water/fat, an imbalance that you can try to reduce or eliminate to regain the initial smoothness.

If you need to add a long-stemmed herb (tarragon, mint, verbena, thyme, etc.) to a recipe, you'll probably only need the leaves and not the stem, so you'll need to remove the leaves. Leaf removal means keeping only the beautiful leaves, and eliminating the ugly stems and leaves, but how do you do...

Parsley stems
Parsley, whether curly or flat, is a delicious ingredient in many recipes, where it is used both raw and cooked. When used raw, in a salad for example, where it always provides, alone or with other herbs, a remarkable freshness, only the leaves are kept. And when used cooked?

Often in a recipe, you have to "baste" vegetables, for example, before sending them to the oven. What the author means by this is that you need to put oil on top of the vegetables to cook them in the oven. Typically, we just quickly drizzle oil over the vegetables, hoping not to miss any, but...
