הָאוֹפֶה כִּגְרוֹגֶרֶת חַיָּב. אֶחָד הָאוֹפֶה אֶת הַפַּת אוֹ הַמְבַשֵּׁל אֶת הַמַּאֲכָל אוֹ אֶת הַסַּמְמָנִין אוֹ הַמְחַמֵּם אֶת הַמַּיִם הַכּל עִנְיָן אֶחָד הוּא. שִׁעוּר הַמְחַמֵּם אֶת הַמַּיִם כְּדֵי לִרְחֹץ בָּהֶן אֵיבָר קָטָן. וְשִׁעוּר מְבַשֵּׁל סַמְמָנִין כְּדֵי שֶׁיִּהְיוּ רְאוּיִין לְדָבָר שֶׁמְּבַשְּׁלִין אוֹתָן לוֹ:
A person who bakes [an amount of food] the size of a dried fig is liable. Just as a person is liable for baking bread, he is liable for cooking food or herbs, or for heating water. These are all one type [of activity]. The minimum amount of water for which one is liable for heating is an amount sufficient to wash a small limb. The minimum amount of herbs for which one is liable is the amount required to serve the purpose for which they are being cooked.
