To make the dough. In the bowl of a stand mixer fitted with the dough hook, combine the milk, yeast, and honey. Let sit 5-10 minutes, until bubbly on top. Add 3 ½ cups flour, the cardamom, salt, eggs, melted butter, and 1 tablespoon lemon zest. Using the dough hook, mix until the flour is completely incorporated, about 4-5 minutes. If the dough seems sticky, add the remaining ½ cup of flour.Cover the bowl and let sit at room temperature for 1 hour or until the dough has doubled in size. Preheat the oven to 350° F. Butter a 12-cup muffin pan. Lightly dust your work surface with flour. Turn out the dough, punch it down, and roll it into a rectangle about 10 x 16 inches. Spread 2 tablespoons softened butter evenly over the dough. Spread over the jam, then sprinkle the lemon zest. Starting with the long edge closest to you, carefully roll the dough into a log, it's going to be a little messy. When you reach the edge, pinch along the edge to seal. Using a sharp knife, cut the log into 12-16 rolls. Place the rolls in the prepared baking dish, they should just fit, but it's ok if they seem slightly big. Cover and let rise 10 minutes.Meanwhile, melt together the honey and 2 tablespoons butter. Bring to a boil, cook 1 minute, then remove from the heat. Brush/drizzle the honey over each roll. Bake the rolls for 20 to 25 minutes, or until golden brown. Watch towards the end to make sure they are not getting too dark on top. To make the icing, whip the ricotta in a food processor until creamy. Add the powdered sugar and lemon zest, then gently pulse until just combined. If the icing is runny, add additional powdered sugar. Spread the icing over the warm rolls. Serve warm and enjoy!
