In 5748 the Rebbe spoke emphatically and repeatedly of the tremendous importance of affixing a Pushka to the wall of your home kitchen. The benefits of this are that when you see a beautiful pushka displayed in a prominent place in the house, you will be immediately inspired to give tzedaka. The Rebbe also encouraged wives and mothers to give tzedaka before cooking.
Amongst the benefits it would bring, the Rebbe said it would help ensure complete fulfillment of all the complex kosher laws. It also adds to the tastiness of the dish and having a positive influence on the chinuch of the children and brings a tremendous amount of brochos to the entire home!
