Combine the seasoning mix ingredients in a small bowl and set aside. Melt the fat and butter in a large skillet over medium heat. When almost melted, add the onions, celery, and garlic; saute 5 minutes, stirring occasionally. Stir in the seasoning mix and cook 5 minutes more, stirring occasionally. Add the stock and pan drippings; bring to a boil over high heat and boil rapidly until liquid reduces to about 1 quart, about 25 minutes. Then crumble the gingersnaps into the stock mixture and whisk with a metal whisk until they are dissolved. Continue cooking 10 minutes, whisking frequently and making sure the gingersnaps are thoroughly dissolved. During this time, taste the gravy; if the ginger flavour is not pronounced,m add the 1 tablespoon brown sugar and the 1 teaspoon ginger or add both to taste. Strain the gravy. Makes 2-1/2 to 3 cups.
