Adding a sofrito mix to my bolognese. Have softened it in the pan, celery and onion lovely, carrots like little shards of rock. Bunged it in the microwave for 5 sodding minutes. Carrots like little shards of concrete. What am I doing wrong and how tf do you soften carrots in something like this? I have no problem cooking normal carrots but whenever I try to put them in a shepherds pie or something they're like little stones.
