Can one drink a glass of milk then 5 minutes later have a piece of angus while following kosher correctly?

Answer 1

No. At the very minimum, there must be a fifteen minute wait between dairy and meat. This also includes a mouth-washing if the consumption of dairy and meat come so close together. Additionally, it is also requisite that the dairy and meat be eaten as distinct meals. For example, you could drink milk at a café and then return home in fifteen minutes, wash-out your mouth, and eat angus beef at home. However, you cannot have cheese as an appetizer, wait fifteen minutes, wash-out your mouth, and then have angus as a main course. The meals must be distinct. (Of course, this answer assumes that the milk and angus are both individually kosher with all requisite requirements for that process.)
