סימן צח סעיף כב
מֻתָּר לִמְלוֹחַ בָּשָׂר לְהַכְשִׁירוֹ מִדָּמוֹ, אֲפִלּוּ הָיָה אֶפְשָׁר לְמָלְחוֹ מֵאֶתְמוֹל. וְדַוְקָא אִם יֵשׁ בּוֹ לְצֹרֶךְ הַיּוֹם. וָאִם יֵשׁ לוֹ בָּשָׂר יוֹתֵר וְהוּא מִתְיָרֵא שֶׁלֹּא יִתְקַלְקֵל מֻתָּר לִמְלוֹחַ הַכֹּל בְּיַחַד אֲפִלּוּ הַרְבֵּה. גַּם מַה שֶּׁאֵינוֹ לְצֹרֶךְ הַיּוֹם, דְּהַכֹּל חֲדָּא טִרְחָא הִיא, אֲבָל בָּשָׂר שֶׁכְּבָר נִמְלַח מִדָּמוֹ, וְכֵן דָּגִים שֶׁהָיָה אֶפְשָׁר לְמָלְחָן בְּעֶרֶב יוֹם טוֹב, אָסוּר לְמָלְחָן בְּיוֹם טוֹב (ת"ק).
It is permited to salt meat to draw off the blood,63See Chapter 36 for details. even if it could have been salted the day before Yom Tov,64Ramah 500:5. Because after the kashering process, the meat must be kept salted in order to keep it from spoiling, and this is detrimental to its taste.(Shulchan Aruch Harav) This is true when it is warm and you have no access to refrigeration. provided you need it for that day. If you have more meat (than you need) and fear it might spoil, you may salt all the meat together,65See Shulchan Aruch 500:5. no matter how much there is, and even that which is not needed for today, for it involves the same labor.66Rashi. We maintain that you have to salt both sides of the meat, so there is a little more labor when there is more meat. Even so, since the prohibition involved is not de’oraisa, the Sages were lenient, if there is concern that the meat will spoil. (Mishnah Berurah 500:22, Shulchan Aruch Harav) But meat that has already been salted and its blood (drawn off),67Magein Avraham. Because it is obvious that you are not salting it to eat it now, for then you would cook it and you wouldn’t re-salt it. But you may resalt it on the second night of Yom Tov, for it could be you want it for the Yom Tov morning meal. The first night of Yom Tov, you may not re-salt it because you should have done it before Yom Tov. (see Machatzis Hashekel 500:17) and fish that could have been salted68Small fish that spoil after a while, when salted, may be salted on Yom Tov. (Mishnah Berurah 500:26, poskim) Even fish that do not get spoiled in salt may be salted on Yom Tov if they were cut open before Yom Tov. (Machatzis Hashekel 500:11) on erev Yom Tov, is forbidden to be salted on Yom Tov.
