Too right! Juice=Flavour. Get those sides ready, & slap that steak straight off the grill on to your plate.
Why do folk keep the juices to make gravy? Coz it tastes gorgeous! But I prefer to eat the juices straight away with the steak, not make gravy out of it.
Let the juices come out whilst you're eating it.
Any juices left over on your plate can be mopped up with a nice piece of bread. Yum!
