Chop the onion as small as possible, but not into porridge. We send the onion to a well-heated frying pan with oil for caramelization.
At this time, grate the carrots on a grater (you can on a large one, you can on a small one - as you like.
When the onion is caramelized, send it to cool on a plate or bowl of a mixer. Now you need to skip the carrots. When the carrots are softened and browned, send them to the onion. Vegetables should cool down.
