Not even the least bit phallic.
Via the excellent FoodFight!: This Polish website has posted a how-to tofu pictorial. It looks simple enough. All’s you need is a bowl (kula), water (woda), soybeans, a handblender, a stove, a saucepan, cheesecloth, some lemons, a juicer, a heavy object to press (naciskaç) your tofu and a kitty (kotka).
You also have to do this in your underwear in a cold room (uh oh — zapotrzebowanie bra). Now enjoy – cieszà si’ waszym tofu!
