Pour the water into a 3 qt. (3lt) saucepan, and add the piloncillo, star anise, anise seeds, cloves, pepper, and cinnamon. Bring to a boil, and simmer until the piloncillo/brown sugar has completely dissolved, about 5 minutes. Remove from the heat and add orange juice.

In a separate large skillet, melt half of the butter. Add the green onions, and sauté for a minute, until the onions soften. Add the pieces of stale bread and allow to toast and absorb the butter. You may have to do this in batches, adding the rest of the butter as needed. Remove the bread pieces to a large ovenproof pan lined with parchment paper. Heat the broiler of your oven.

Once all of the bread has been passed through the butter, pour any remaining butter over the bread, but discard the onion pieces. Briefly toast the bread under the heated broiler, about 3 minutes until it is golden brown. Remove the pan of toasted bread, and then set the oven to 350°F (176°C).

Place a layer of the toasted bread in a 3 qt. (3lt.) baking dish and then sprinkle over half of the cream cheese, almonds, oranges and golden raisins. Top with another layer of toasted bread, and then continue layering, ending with a top layer of bread. Gently ladle over the sweet spiced tea. The baking dish should be quite full, but not overflowing. There is no need to cover the capirotada while it is baking, but you can do so if you like for a more tender crust.

Bake for one hour, until most of the sweet spiced tea is absorbed. Remove from the oven and allow to cool briefly before serving. Ganish with powdered sugar.
