Yosef Karo Shulchan Aruch — 118 Laws of sealing food and how to send it with a gentile

Wine or meat or a piece of fish that does not have on it a sign, which one deposits or sends with a non-Jew, it needs two seals. But cooked wine and beer or wine that has other things mixed in it such as honey, and so too vinegar, milk, brine, bread, and cheese and anything that is prohibited by the words of the scribes [i.e. rabbinically] that one deposits in the hand of a non-Jew, is permitted by a single seal.

Yosef Karo Shulchan Aruch — 118 Laws of sealing food and how to send it with a gentile

A Jew and a non-Jew that share together two pots, one by the other, this one for kosher meat, this one for non-kosher meat, this is permitted, and we are not concerned that perhaps when the Jew returns, the non-Jew will have switched kosher and non-kosher , even if the Jew's meat is better, and even if he vocalizes that it is better, it is permitted, and we are not concerned that perhaps they will splash and spill into one another.
