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. |
