Jirka and his wife Marica write the popular blog called KitchenStory. In cooking, they focus mainly on healthier variations of food: they cook without gluten and without lactose. They travel a lot, not just for food. Today they share their passion for healthy and quality food with thousands of their fans. Both of them belong to the gourmet group of Lukáš Hejlík (Gastrokroužek) and their recipes are currently published as a part of Gastrokroužek´s cookbook. In 2017 they released their own cook book A Couple in the Kitchen.
