Mine is.... Cook your carrots whole!
Just that, when you have carrots for dinner. Cook them while. Don't peel or chop them. (Peel if you must)
However, just cook them as they come and cut up once cooked.
They will be the most carroty carrots you've tasted.
I tell people this, they dont believe me...and then normally a few weeks later they'll surreptitiously way and are converts
Wats your top tip?!
