מי פירות בלא מים אין מחמיצין כלל ומותר לאכול בפסח מצה שנילושה במי פירות אפילו שהתה כל היום אבל אין יוצא בה ידי חובתו מפני שהיא מצה עשירה וקרא כתיב לחם עוני:

THE LAWS OF WETHER FRUIT JUICES LEAVEN; 7 SECTIONS Fruit juice without water does not leaven at all and is permitted to eat on Pesach Matzah which was kneaded with fruit juice, even if [the dough] was idle all the day. However, one may not fulfill his obligation with it, because of its Matzah Ashirah, and the verse states "lechem onee".

Fruit juice with water accelerates leavening more than other dough, therefore one should not knead with them and if kneads with them he should bake it immediately.

It is permitted to knead with wine even though it's impossible that there wasn't a drop of water which fell into it at the time of pressing. Even initially, it is normal to put water at the time of pressing in order to permit [impurities] via connecting flow. Nevertheless, we are not concerned about this since afterward, the water is neutralized in the [proprotion to the] wine prior to kneading the dough.

Egg liquid and all other liquids are generalized with fruit juice. REMA: and in these countries [Ashkenaz] it is not practiced to knead in fruit juice and even to batter the Matzot is only practiced after they are baked and still hot. One should not deviate from this when not a time of need. The needs of the sick or elderly are [examples] of this.

[When] kneading dough in fruit juice, it is good to do with less than the measure of an "eesarone"[43.2 eggs] so that one isn't obligated in Challah tithe.

Wheat which was found in honey or wine and vinegar is permitted, provided water has not mixed into it.

One should sift the salt prior to Pesach [so that] there is not wheat within it, for when the salt becomes wet, a minute amount of the moisture enters the wheat and it will leaven.
