READ ALL THE WAY THROUGH FIRST, AND DECIDE ON TEXTURE WANTED.
Bake 1 large potato per person (or 3 to 2 if you think you need to). They must be large ones.
You can microwave, BUT THEY MUST BE FINISHED IN THE OVEN- the crispy/hard skin is a must.
Grate Cheese- Now grate a tad more. Now do another couple of grates per person. (this is n’t really a ‘measure’ recipe!)
The Difficult bit
Cut potatoes in half- longways, and probably so the halves are shallow as you can get- you will need to stand these like boat hulls to finish, so think ahead
Now VERY CAREFULLY (No more careful than that) scoop the flesh out the skin. It is important you do not break the skin (which is why they have to be crispy). I usually cut round with a paring knife, then use a dessert spoon. It is better to cut too shallow- you can always scrape more out, you can’t repair the skin.
BUT you need to do this ASAP so flesh is still as hot as possible.
Mash flesh and cheese- add a knob of butter, but not too much- you are not going for creamy mashed potatoes- and a little black pepper and Worcester sauce. Basically you want thick (but not too lumpy) mashed potatoes.
Scoop the Cheesy mash back into the skins.
Sprinkle with a more grated cheese, (and Worcester if you like)
Finish under grill until cheese on top is golden (this may be a better place to add the second lot of Worcester, like cheese on toast).
I posted this on a wargame site, and a couple of guys thought up additions- chopped crispy bacon and/or chives, so don’t be afraid to try adding stuff.
