Ingredients:-

• 3 tablespoons butter
• 1/2 medium onion, sliced
• 2 Granny Smith apples
• 2 teaspoons apple cider vinegar
• 1 pinch salt
• 3 cups sparkling cider
• 1-1/2 cups brown gravy
• 1/4 teaspoon salt
• 1/4 teaspoon freshly ground black pepper
• Olive oil

Apple Sauce:

• In a sauté pan, melt the butter and sauté the onions until soft. Peel, core, and thinly slice the apples. Add to the onions, and sauté until the apples are soft, about 3 to 5 minutes more. Remove from the heat and add the vinegar and salt. Refrigerate until cold.

Cider Sauce:

• In a medium saucepan, simmer the sparkling cider until only 1/2 cup remains, 30 to 45 minutes. Whisk in the brown gravy; simmer gently for 10 minutes. Remove from heat.
