Is meat cooked in a sous vide considered “tzli kedar” which many people do not eat at the seder?
The reason why we don’t eat tzli kadar is because of the way it is cooked, since it is cooked without water from the outside seeping thru it and cooking it. Numerous poskim, including R’ Y. Zilberstein, R’ H. Shachter shlit”a and others say not to use it for the seder for this reason. Since it is really cooking in it’s own juice it is like tzli kadar.
Have a good Yom Tov
