In a private audience, the Rebbe encouraged a rabbi to start a campaign in his city to purchase kosher food.
"Why would I want the people to purchase kosher food?" the rabbi asked. "Their kitchens are not kosher." Once the kosher food would be cooked in the non-kosher kitchens, it would become non-kosher too.
"Currently, in your city, the general perception is that kosher food is not tasty," the Rebbe responded. "Once people eat kosher food and see that it is tasty, they will realize that it is not that removed from their current eating habits to eat kosher food.
"Once they begin eating kosher food, it will be much easier for them to make their kitchens kosher."
