Try to use carrots that are similarly sized so they cook at the same rate. However, if the top halves of some are very thick, simply cut those sections in half lengthwise. We liked these carrots with cumin seeds, but an equal amount of whole coriander seeds also was delicious. To crush the cumin or coriander seeds, use a mortar and pestle or grind them against a cutting board with the back of a small skillet.
