In the galley: Include a bit of vinegar in marinades to help tenderize meat. After cutting an onion, rub vinegar on your hands to remove the odor. Set out an open dish of vinegar to keep fruit flies away. When your galley-sink drain emits a foul odor, is slow to drain, or is completely clogged, try the following: Pour baking soda as far into the drain as you can. (I use a skewer to push at least half a cup of baking soda deep into the drain.) Heat two cups of vinegar. Slowly pour hot vinegar into the drain. If you immediately plug the sink, the pressure will help push whatever is clogging it out the through-hull. Only try this if you trust your plumbing fittings! Otherwise, the baking soda/vinegar mixture will bubble up into the sink, often bringing the offending particles with it. Continue pouring the hot vinegar into the sink until all the baking soda is neutralized.
