What would be the status of the coffee maker cone shown below if it were to be used to make a cup of coffee in a dairy mug? Would it become dairy? Would it remain parve?
Here's how it works. It holds a coffee filter, into which coffee grinds are placed, and over which hot water (approximately 165-180°F) is poured, and it has a small hole at the bottom, through which the coffee-enriched water drips into the cup below.
Does it make a difference if the cup was used, and for what, within the previous 24 hours?
