   1                    serrano pepper -- halved and seeded
   2                    chipotle peppers -- halved and seeded
   2      cups          chicken or veal stock
   2      teaspoons     dry mustard
     1/3  cup           raspberry vinegar

                        salt to taste

Preparation:

Smoke all vegetables and chiles for 20 minutes. Transfer the ingredients to a medium saucepan with the stock. Bring to a boil and reduce the liquid by at least one third. Wisk in the mustard, strain and set aside. In a small saucepan, whisk together the sugar and vinegar. Bring to a boil and continue cooking until the mixture becomes syrupy, about 3 minutes. Add to the strained stock and whisk in the catsup. Strain the sauce through a fine strainer and season with salt to taste.
