Having been given the Lotus Grill, and I am not wanted to deal with possible alternatives to the "Genuine accessories", I have decided for this coal and the associated fuel paste. I'll probably stick with it (despite the price), because in the mentioned combination makes the grilling fun.
We need a couple (like sitting at the River Elbe when grilling) do not even fully the coal bin to comfortably eat and barbecue to have all the time hot. Temperatures that this coal is developed enormously and also this heat is full after only 3-5 minutes since.
