📖 Instructions

1. First things first, gather all your ingredients and equipment. It makes the process so much smoother, trust me. No one likes scrambling for the cinnamon mid-stir! You'll need a medium saucepan, a whisk or a traditional molinillo if you're feeling fancy, and your serving mugs ready.
2. In your medium saucepan, pour in the milk. Don't turn on the heat just yet! Add the chopped chocolate or chocolate tablets, cocoa powder, sugar, cinnamon stick, and the pinch of cayenne pepper (or chili powder if you prefer). If you're using a cinnamon stick, make sure it's whole and unbroken; it'll infuse better.
3. Now, turn the heat to medium-low. Slowly warm the milk and chocolate mixture. Use your whisk or molinillo to stir continuously. This is key! You want the chocolate to melt evenly and not stick to the bottom of the pan. Keep stirring until the chocolate is fully melted and the sugar has dissolved, forming a smooth, rich liquid. This should take about 5-7 minutes. You'll see the color deepen and the aroma will start to fill your kitchen – pure heaven!
4. Once everything is melted and smooth, increase the heat slightly to bring the mixture to a gentle simmer. Do not let it boil vigorously; we're aiming for warmth and frothing, not boiling over! Continue to whisk or use your molinillo vigorously. This action incorporates air, creating that beautiful foam that’s characteristic of authentic Mexican hot chocolate. You're looking for a good head of froth on top, so don't be shy with your whisking!
5. Carefully remove the saucepan from the heat. Take out the cinnamon stick – you've extracted all its wonderful flavor now. If you used a powder, you can skip this step, naturally.
6. Pour the hot chocolate into your favorite mugs. If you'd like, garnish each mug with a sprinkle of extra cinnamon, a tiny pinch of chili powder for an extra kick, or even some mini marshmallows if you're feeling playful (though traditionalists might gasp, I say enjoy it how you like!).
7. Serve immediately and savor every warm, spicy, chocolatey sip. This drink is best enjoyed fresh and hot. Trust me, it won't last long, but any leftovers can be stored in the fridge and gently reheated, though the froth might not be as pronounced.
