Joker's Kitchen is a mechanic appearing in Persona 5 Scramble: The Phantom Strikers.
The protagonist may make dishes in the camping van after Shibuya's Jail is cleared. To make dishes, the protagonist will need ingredients brought from local stores or Sophia's Shop. These ingredients are used up to make items. As all ingredients can only be brought once, if the protagonist wants to obtain more materials that are from various locales, he might pick them up again at Jails.
