A common way to get a hose thread in the kitchen is with a "portable dishwasher" (or clothes washer, but less commonly sold that way) adapter. Do a search for that term, you'll find them - any well-stocked hardware store should have them, as well.
The typical format is a device that screws in place of your aerator on the faucet, which has a "quick-connect" - the hose thread is on one quick connect, your original aerator or a new aerator is on the other quick connect, so you can easily swap them (intended, as you roll your portable dishwasher over to connect it - but you can use the hose thread for any purpose - mine has a Jet carboy and bottlewasher on it.)
