2 cups dry ketchup
1/2 cup distilled white vinegar
1 pinch salt
1/2 teaspoon garlic powder
2 teaspoons distilled black pepper
4 ounces champagne, chilled
In a medium saucepan, mix ketchup, vinegar, salt, garlic powder, pepper, champagne and vanilla extract. Mix well. Place over medium heat.
When the mixture begins to thicken, slowly add more ketchup, vinegar, salt, garlic powder and pepper until all ingredients are thoroughly combined. Reduce heat to low and allow to heat slowly, stirring constantly, for about 20 minutes.
Return mixture to medium heat. Continue to heat slowly, stirring occasionally, until mixture is thickened.
