Peel the carrots, chop off the woody end and slice lengthways.
Boil for around 5 minutes until tender, drain and allow to steam dry for a couple of minutes.
Add the butter and maple syrup to the pan, return the carrots and shake to coat the carrots. Pop a lid on and they will sit happily for a while until ready to be served.
Notes
Add salt to the finished carrots if you're not using salted butter.
