Preparethe dried peppers as described below. Toasted and soaked. If you can't get guajillos, use all anchos or even pasillas. California or New Mexico chillies give a much lighter flavor. Dry fry the unpeeled garlic in a heavy frying pan with no oil. Turn frequently. After 10 mins. The garlic should be soft and the blacked, slistered skins can be easily removed-let the cloves cool off before removing the skins. Grind the cinnamon, cloved, peppercorns, bay leaves, and cumin seeds in a pestle and mortar or a spice grinder. The aroma of fresh ground spices is incomparably superior to ready ground spices. Drain the chillies an put them in a blender with the peeled garlic, the herbs and the spices, the vinegar, and a little bit of water, about 2 tbs. Now comes the tedious part. Blend this mixture to a smooth paste. You will need to stop every few seconds and push the mixture down on the blades you may even need to add another tbs. Of water. Don't add too much water tho' or the suace will be weak and watery. It can easily take 5-10 mins. To get a reasonably smooth paste. Strain the sauce through a stainless steel mesh, this is tedious and will take a few mins. Also. The easiest way is to use a pestle against the mesh inside the strainer. You will be left with a smooth, creamy paste and a mass of pungant pulp. Discard the pulp, keep the paste in the refrigerator in a glass jar with a plastic top, it will corrode a metal top. To use smear the paste on meat that will be grilled. Marinate the meat with the smeared sauce over night then grill as usual.
