Caramelized Onion And Apple Chutney - cooking recipe

Ingredients

3 tablespoons butter
3 tablespoons vegetable oil
3 large yellow onions, roughly chopped
2 large granny smith apples, peeled, cored, and cut into medium cubes
3/4 cup apple cider vinegar (I strongly suggest using the Heinz brand)
1/2 cup light brown sugar
3 tablespoons pure maple syrup
1 teaspoon mustard powder
1/2 teaspoon caraway seeds (optional) or 1/2 teaspoon celery seed (optional)
1/2 cup dark seedless raisins (optional) or 1/2 cup golden seedless raisins (optional)
kosher salt, to taste
black pepper, to taste

Preparation

In a 12-inch (or larger) skillet, melt the butter over medium-high heat. Add the oil, and when hot, add the onions to the skillet, along with a pinch or two of kosher salt and a few grinds of black pepper. Cook, stirring often, for about 10 minutes, then lower the heat to medium and continue to cook, stirring occasionally, until the onions turn a rich golden brown, or about another 30 to 40 minutes. Do not rush this process as you do not want any onions to burn or dry out.
Meanwhile, in a medium mixing bowl, whisk together the vinegar, brown sugar, mustard, celery or caraway seed (if using), and pure maple syrup along with more salt and pepper; set aside.
When the onions are ready, raise the heat to medium-high again and add the apples. Cook, stirring frequently, for about 5 minutes, or until the apples just begin to soften. Add the vinegar mixture and deglaze the pan by scraping the bottom. If you're using a nonstick skillet, there will be nothing to deglaze. Stir in the raisins (if using) and cover the skillet, lower the heat to medium-low, and let simmer for 15 to 20 minutes, or until the apples are soft. Remove the lid and raise the heat back to medium-high. Cook the mixture, stirring often, until the liquid in the pan thickens enough that you can drag a spoon across the bottom and the liquid flows slowly back in, or is syrupy. Remove from the heat and set aside to cool. Taste and adjust the seasoning.
This stuff is delicious and goes well with grilled or roasted pork.
