The Easy Way To Drain Canned Fish Without A Strainer
An easy way to drain canned fish without a strainer is to use a small plastic cup, which has a base that can fit perfectly within the circumference of the tin.
For this trick you'll need to use a can opener that cuts around the inner periphery of the lid rather than a modern safety version that smoothly cuts below the exterior rim.
After the can is open, place it in the sink with the lid still inside. Place the plastic cup's base on top and turn it over so that the open side of the cup is in the sink.
Press the bottom of the can to push out as much liquid as possible before lifting it off and discarding the lid. You should be left with a well-drained can of fish.
