You can also cut carrots into smaller pieces. It is very important to cut the carrots into same size pieces for homogeneous cooking. They can be slices, half slices or squares of approximately 1 inch.
The cooking point should be al dente. To do this, check the texture with the tip of a knife. Do not steam for more than 12 minutes.
Ice water will cut the cooking leaving the carrots ready. If you don't have ice you can chill them several times in cold water.
