649. Cooking and Baking
Shabbos 9:1
One who bakes in the volume of a dried fig is liable. This is true for baking bread, for cooking food and for heating water; they are all the same labor. The minimum volume of water for which one would be liable is enough to wash a small limb (i.e., a baby’s pinky toe). The minimum volume of herbs for which one would be liable is enough to fulfill the purpose for which one is cooking them.
Shabbos 9:2
If a person puts an egg next to a kettle so that it will get partially cooked, he is liable if it gets cooked because cooking with something heated by fire is the same as cooking with fire itself. Similarly, if someone washes aged, salted fish - or another fish that is soft and thin - using hot water, he is liable because the hot water completes the necessary cooking. This applies in all similar cases.
