3,368. Mixtures Involving Different Kinds

Terumos 15:7

As was discussed, if terumah got mixed with something of a different type, the determining factor is if it imparts taste. Let’s say that a chopped onion was cooked with other food. If the onion is terumah and the other food is secular and it absorbs the taste of the onion, then the other food is prohibited to non-kohanim. Conversely, if the onion is secular produce and the other food is terumah and the other food imparts taste to the onion, then the onion is prohibited to non-kohanim.

Let’s say that a dry onion was put into cooked lentils. If the onion was uncut, it is permitted. If it was chopped, then it depends on whether it transmitted its taste. If one cooked the onion together with the lentils, regardless of whether it was whole or chopped, we calculate whether it imparted taste. As far as the rest of the food, regardless of whether the onion was put into it after it was cooked or cooked with it, and regardless of whether the onion was whole or chopped, we calculate whether it imparted taste.

When an uncut onion is put into cooked lentils we don’t calculate the transmission of taste because a whole onion won’t transmit its taste to cooked lentils, but if the onion is soft, then it’s like a chopped onion. Similarly, if the onion’s tip or its peel was removed, or if the onion was wet, then it’s the same as if it were chopped. Wild onions are calculated to see if they imparted taste regardless of whether they’re wet or dry, whole or chopped.
