So being a show designer, where its my job to make stuff, I thought hmmmmm lava rock , why isn't granite a lava rock? And so begins our saga!
Step 1: What You Need
I went to my local headstone guy and he gave me an off-cut of polished black granite for free. Irish people are nice like that! I then cut it into 4 pieces each about 2inches thick and the width of my hand (4.5 inch) with 1 polished side where the steak will be cooked.
To cut the granite. Cut a line in the stone with an angle grinder with a stone cutting disc
Then with a coal chisel and hammer crack the stone on the cut line. This will break the rock in straight lines.
2. Roasting dishes big enough to take a rock and able to handle heat.
3. Tin Foil (aluminium foil)
4. Gas cooker ring or any oven
5. Metal utensils to lift the rock
6. Place matts
Step 2: Heat The Rocks
Step 3: Prepare The Dishes
Then bend it into a circle and place it in the dish.
This is what the rock will sit on.
Step 4: Check The Rocks Are Hot Enough
To test how hot they are you can drop a drop of water on them and see if it sizzles off and how fast.
Once hot enough the rock should retain its heat and be able to cook steak for up to 45mins or more.
Step 6: Remove Rocks From Heat
I usually use a metal potato masher and a metal tongs to lift the rocks. I rest the rock on the masher and hold it with the tongs.
Make sure the dishes are close to the cooker.
Lift the rocks and place them on the foil ring in the dish.
If in the oven remove them carefully wear oven gloves but don't trust that you can handle the rocks even with the gloves. It may be too much for even the gloves.
Step 7: Place Steak On Rocks
If its very thick you can cut it into slices and fry it as you eat it ;-)
Add your fries mushroom etc on the side.
Season to taste with pepper, salt, garlic etc
Step 8: Bring It To The Table
Enjoy amazing steak cooked in front of your very eyes! Great for wow factor dinners like first dates or parties!
