Peel the carrots and cut into slices that are not too thin. Wash the coriander, pluck from the stalks and do not cut too finely.
In a pan that fits a lid, heat the oil over medium heat (7 out of 9 for me). Add the carrots, stir once and put the lid on. Simmer until the carrot slices have the desired firmness.
Scatter the grainy stock and add the coriander, stir and let stand covered for another minute or two without heat.
For me this was a main course, as a side dish it is enough for two people.
