Caramelized Onion And Cranberry Puff Pastry Bites

• 1 1/2 pounds sweet yellow onions (about 2 very large), very thinly sliced
• 2 tablespoons sweet butter
• 1 tablespoon olive oil
• 5 sprigs fresh thyme (lemon thyme is especially good)
• 1 tablespoon sour cream or creme fraiche
• 1 sheet puff pastry, defrosted but still cold
• 24 fresh, whole cranberries
• sea salt
• freshly ground black pepper

1. In a large skillet, heat the onions, butter, and olive oil over medium-high heat. Cook, stirring constantly, about 5 minutes until the onions begin to shrink down a bit.
2. Lower the heat to medium-low. Stirring every few minutes, caramelize the onions for 30 minutes. Add in the sprigs of thyme and continue to cook for another 5 minutes, still stirring regularly and lowering the heat as necessary, until the onions reach a uniform toasty brown color. Cooking them slowly over a low heat will help make the onions sweet and evenly browned, so take your time.
3. Remove the onions from the heat. Carefully remove the thyme stems. Stir in the sour cream or creme fraiche.
4. Preheat the oven to 400u0b0F. Directly on a Silpat or on parchement paper, roll out the pastry sheet to about 12 inches by 8 inches. Score the sheet into 2-inch by 2-inch squares. Place the Silpat or parchment on a baking sheet.
5. Top each square with a heaping tablespoon of the caramelized onions. Place a whole cranberry atop each mound of onions.
6. Sprinkle salt and fresh pepper very lightly over the squares. Bake for about 15 minutes, rotating the pan about halfway through cooking. The bites are done when the edges of the puff pastry have browned and the cranberries have shrunken.
7. Cool for 10 minutes on the baking sheet. Serve warm or at room temperature.
