Mexican Tomato Sauce
2-1/2 to 3 lbs chile peppers
18 lbs tomatoes
3 cups chopped onions
1 tbsp salt
1 tbsp oregano
1/2 cup vinegar

Yield: About 7 quarts

Procedure: Caution: Wear rubber gloves while handling chilies or wash hands thoroughly with soap and water before touching your face. Wash and dry chilies. Slit each pepper on its side to allow steam to escape. Peel peppers using one of the following methods:

Oven or broiler method: Place chilies in oven (400° F) or broiler for 6-8 minutes until skins blister.

Range-top method: Cover hot burner, either gas or electric, with heavy wire mesh. Place chilies on burner for several minutes until skins blister. Allow peppers to cool. Place in a pan and cover with a damp cloth. This will make peeling the peppers easier. After several minutes, peel each pepper. Cool and slip off skins. Discard seeds and chop peppers. Wash tomatoes and dip in boiling water for 30 to 60 seconds or until skins split. Dip in cold water, slip off skins, and remove cores. Coarsely chop tomatoes and combine chopped peppers and remaining ingredients in large saucepan. Bring to a boil. Cover. Simmer 10 minutes. Fill jars, leaving 1-inch headspace. Adjust lids and process according to the recommendations in Table 1 or Table 2 depending on the method of canning used.

*After the canner is completely depressurized, remove the weight from the vent port or open the petcock. Wait 10 minutes; then unfasten the lid and remove it carefully. Lift the lid with the underside away from you so that the steam coming out of the canner does not burn your face.
