# Just as it is forbidden to knead two ingredients together so too it is forbidden to pour one onto the other so that they will mix automatically. Therefore it is forbidden to pour water onto flour or flour onto water on Shabbat. <ref> In Gemara Shabbat (18a) there is a dispute whether one is liable for violating Losh by simply pouring liquid into flour or only if one both pours in the water and mixes it. The majority of the Rishonim hold that one isn't biblically liable until one has both poured in water and mixed it into dough (Mishna Brurah 321:50), nonetheless, Mishna Brurah 321:57 (quoting the Magan Avraham) there is a rabbinic prohibition even for just pouring liquid into flour or the opposite. This is also the ruling of Shemirat Shabbat KeHilchata 8:5, 39 Melachos (by Rabbi Ribiat, vol 1, pg 531), and Menuchat Ahava 9:1. </ref>

==Making egg salad==
# To avoid all issues it’s preferable to make egg salad before Shabbat. However, if one didn’t, one may do so on Shabbat in the following manner: One may peel the eggs right before the meal and then mash them even with the prongs of a fork. Then peel the onions right before the meal and cut them in slightly large pieces and then mix it. The minhag is to mix in oil without any variations, however, it’s proper to make above variations (in order of putting in ingredients and way of mixing). <Ref>Shemirat Shabbat KeHilchata (in new editions 8:28) </ref>
## One mix in cooked potatoes using the handle of a fork, or if the potatoes are very soft because of the cooking one may mix it with the prongs of the fork. <Ref>Shemirat Shabbat KeHilchata (in new editions 8:28) </ref>
## If egg shell got mixed into the salad one may only remove it together with a bit of other food, but preferably one shouldn’t remove the egg shell but just eat around it. <Ref>Shemirat Shabbat KeHilchata (in new editions 8:28) </ref>
