I made this a couple of weeks back and I'll be making it again and again. You will need 4 or 5 large potatoes peeled and sliced as thinly as possible. 5 or 6 cloves of garlic finely sliced. 1 large onion finely sliced. 50grams of butter. 300mls of double cream Sea Salt and Cracked Pepper. 1 deep foil dish buttered. Place a layer of onions on the bottom, then a layer of potatoes, sprinkle the garlic on and season with salt and pepper and then repeat until all your ingredients have run out. Tear small bits off the butter and place over the top then pour the cream all over it. Mine took 2 hours to smoke, but it wasn't cooked all the way through, so put it in the oven for a further 40 minutes to cook thoroughly. This is a French recipe taken to another level. I used Jack Daniels Barrel wood. Enjoy.
