Tractate Orlah - Chapter 2 - Mishnah 7 ערלה פרק ב׳ משנה ז׳

[We rule sometimes] leniently and [sometimes] stringently, [in the case of] a species [mixed] with a different kind of species. How so? If crushed beans were boiled together with lentils, and there is enough of them [the crushed beans] to impart flavor, [then] whether there is enough to become neutralized in one-hundred-and-one, or there is not enough to become neutralized in one-hundred-and-one, it is prohibited. [But] if there is not enough to impart flavor, [then] whether there is enough to become neutralized in one-hundred-and-one, or there is not enough to become neutralized in one-hundred-and-one, [the mixture] is permitted.
