וחכמים אומרים: תעלה, ותיאכל ניקודים, או קליות, או תילוש במי פירות, או תתחלק לעיסות, ובלבד שלא יהא במקום אחד כביצה.

And the Rabbis say: Let the se’a of teruma arise and be nullified by the 100 se’a of non-sacred produce, and then all 101 se’a will be considered non-sacred. Nevertheless, the mixture may not be allowed to come in contact with water, so that it does not become susceptible to ritual impurity, and therefore it must be eaten dry or roasted. Or alternatively, it may be kneaded with fruit juice, which does not render a substance susceptible to impurity. Or alternatively, if one wants to knead it with water, it may divided into small batches, provided that there is not an egg-bulk of teruma in a single batch, as an egg-bulk is the minimum volume needed for food to be susceptible to contracting impurity.

ותני עלה: אותן חולין

And it is taught in that regard: Concerning those 100 se’a of non-sacred produce,
