Chapter 5
Laws Relating to Squeezing Fruit on Shabbath and Yom Tov
2.d. On the other hand, lemon may be sliced and put into a drink, such as tea or cold water, even though some of the juice will come out by itself, but
1) it is forbidden to squeeze the lemon with one’s hand or with a spoon even while it is in the drink and,
2) on Shabbath, one must be careful that the drink should either
a) have a temperature of less than 45 degrees centi- grade (113 degrees Fahrenheit) or
b) be in a keli shelishi. (In this latter connection, see Chapter 1, paragraphs 2, 53 and 57.)
