Reference for Berakhot 76:5

בשלמא כל שתחלתו שהכל נהיה בדברו שלקו בפה"א משכחת לה בכרבא וסלקא וקרא אלא כל שתחלתו בפה"א שלקו שהכל היכי משכחת לה א"ר נחמן בר יצחק משכחת לה בתומי וכרתי

It is quite right that food which in its original state requires "...By Whose word all things exist," if cooked requires "...Who createst the fruit of the ground" ; for it is found thus in the instances of cabbage, beet and the pumpkin. But something which in its original state requires "...Who createst the fruit of the ground," if cooked requires "...By Whose word all things exist" — where is such to be found ? Rab Nahman b. Isaac said : There are the instances of garlic and leek.
