What to do with those juices…
At lower temps, Sous Jus will range from pink to quite dark. As its temperature increases, it will become more cloudy and gray as I mentioned. Next time you finish a project, take a couple of extra minutes and try this:
- Pour the juice into a clear, microwaveable container–tall enough so that it won’t boil over.
- Place the container in the microwave and process until it just boils. You can use a pan, too, I just hate washing pans.
- Moisten a coffee filter/paper towel and place in a strainer. Moistening the filter prevents the liquid from clinging to the paper fabric. Pour the harvested juices through the strainer.
- Examine and smell the solids trapped by the filter. Congratulate yourself for deciding not to just grind them up and leave them in there.
- Discard the solids and use the clarified liquid. It will be strong in flavor and gelatin. If there was salt in the bag, it may be salty. This is further testimony to the fact that even though salt CAN penetrate the surface of the meat, it does not really have time to do so. Even under ideal conditions (40 F/4 C), salt can only travel about 1″ every 4 days as part of the traditional curing process. As the temperature increases, the meat exerts too much outward pressure for even the salt to enter.

A lot of devotees now speak of reducing the Sous Jus to utilize it in a sauce, just like you would a stock. Keep in mind that “reductions” are first made by ADDING water to extract flavor from bones, vegetables, etc. Then, that liquid is reduced to re-concentrate the flavors. This is not necessary with sous jus because the liquid was never added in the first place. The sous jus can be put to good use just the way it is. It keeps well in the fridge.
