On this occasion, I’m going to go, that you yourselves can build their own furnace of Earth, in his country house, or in the garden of his house, if you have enough space, and believe me, will not regret, just imagine that from a day before, rather, from the night before, the family gathered pouring firewood kiln to have him on the verge of heat, and thus be able to enjoy a rich earth oven barbecue, or a delicious BBQ beef head, believe me, is an unforgettable experience. The first thing they have to do, is, dig a hole about a meter, a meter and a half deep, the depth of the hole depends on the amount of meat to be cooked, you, the diameter of one metre hole determines that approximately, trying that the diameter of the hole is as uniform as possible, even when the truthnor is so uniform, nor so flush, but that this does not discourage it, since it does not influence anything with the end result. Since you have your hole for barbecue, have to fijar the walls and the floor of the oven, how do this?, very easy, by wetting and compacting, is one of the techniques that I personally worked much: buy in the supermarket, or in any market, a water spray, those ladies used to iron clothes, I have also seen who use it for dipping and washing the leaves of plants of interiors. As with its full spray, and in hand, proceed to moisten the walls, and your oven’s ground floor, since it has completely damp, (without Earth dropping by excessive moisture) flatten the earth gently, remember: wet and compact. Are you almost finished construct your oven from Earth for their barbecues, the final step is: get two dozens of river stones, size regular, (not so girls) and also two or three loads of firewood, preferably of encino, if you don’t know where to buy firewood, use any of the search engines of Internet, I would recommend the Google. .
