📖 Instructions

1. Prepare your orange zest: Using a microplane or a fine grater, carefully zest about half of one medium orange. Be sure to only get the bright orange part and avoid the white pith underneath, as it can be bitter. Set aside a small pinch of zest for garnish later.
2. Infuse the milk: In a medium saucepan, pour in the milk. Add the majority of the orange zest you just prepared (leaving a small pinch for garnish) along with the cinnamon stick, if using. Heat the milk over medium-low heat, stirring occasionally, until it's steamy and just begins to bubble gently around the edges. Do not let it come to a rolling boil; we want to infuse, not scald.
3. Steep and strain: Once the milk is heated, remove the saucepan from the heat. Let it sit for about 5-10 minutes to allow the orange zest and cinnamon to infuse their flavors more deeply into the milk. This step is crucial for that lovely citrus 'lift'. After steeping, remove the cinnamon stick and then carefully strain the milk through a fine-mesh sieve into another clean saucepan or a heatproof bowl to remove the orange zest. This ensures a silky-smooth hot chocolate without any pulpy bits.
4. Melt the chocolate: Return the strained, infused milk to the saucepan. Add the chopped dark chocolate, cocoa powder, and sugar. Return the saucepan to very low heat.
5. Whisk until smooth: Continuously whisk the mixture gently. The chocolate will gradually melt and combine with the milk. Keep whisking until the mixture is completely smooth, glossy, and all the cocoa powder and sugar have dissolved. This usually takes about 3-5 minutes. Don't rush it; a patient whisk ensures a creamy texture.
6. Add the orange juice: Once the hot chocolate is smooth and hot, remove it from the heat. Stir in the fresh orange juice. A little squeeze really brightens everything up without making it taste like orange juice concentrate.
7. Taste and adjust: Take a small sip. Does it need more sugar? More chocolate? Adjust to your liking. Remember, you can always add a tiny bit more of something, but you can't take it away!
8. Serve and garnish: Carefully pour the hot chocolate into your favorite mugs. For an extra special touch, you can top it with a dollop of whipped cream and sprinkle with that small pinch of reserved fresh orange zest. A tiny piece of candied orange peel also looks beautiful. Enjoy immediately!
9. Cleanup tip: Rinse your saucepan right away to prevent chocolate from sticking and becoming hard to clean. Trust me, future you will thank you.
