Reference for Zevachim 62:12

לאכול ולהקטיר איצטריך ס"ד אמינא התם הוא דלאו כי אורחיה קא מחשב אבל הכא דבהאי כי אורחיה ובהאי כי אורחיה אימא ליצטרף קא משמע לן:

you can infer this by deduction from the first clause, [viz. ,] only [if he intends] to eat what normally eaten, but not [if he intends to eat] what is not normally eaten. Then seeing that [intentions] to eat [what is normally eaten] and to eat what is not normally eaten do not combine, is it necessary [to teach about intentions] to eat and to burn [that they do not combine]?<span class="x" onmousemove="('comment',' Surely not.');">¹¹</span>
