I love the lemon juice thing its so cool and much better then the ordinary one I have home where I have to roll and squeeze the lemon myself to get the juice
It's really cool to see what people come up with but honestly a with little skill and a good knife, you can do all of these things and never have to worry about washing or sharpening all these crazy contraptions. Plus knife skills always impress the ladies when you're cooking dinner for two. :)
The one problem with that steak tenderizer, is that the harmful bacteria on steak is on the outside of it (that's why you only have to cook the outside completely) therefore using it would have a high chance of spreading that bacteria inside of the steak...
My mom still uses kathipeta a traditional way not even knife . The point of using machine is no human intervention but still we r doing lot of work and cleaning. Wonder if any1 really buys these stuff
