How to make
Combine the ingredients for the marinade without the cherry tomatoes. Clean the cherry tomatoes, cut them in half and pour the marinade over them. Leave them covered while you prepare the polenta.
Bring the water with the salt to a boil, pour in the corn flour while stirring.
Lower the heat, add the butter and boil about 30 min, stirring regularly.
Take the ready polenta off the stove and mix it with the sour cream, which you can substitute with mascarpone or cream cheese.
