Place the rolled oats in a sieve and rinse under cold water to remove excess starch. This helps keep your avena smooth and prevents it from becoming too thick.

In a large saucepan, combine the rinsed oats and water. Bring to a gentle boil, then reduce the heat to low. Add the cinnamon stick and cloves, letting everything simmer for about 15 minutes until the oats are soft and the mixture slightly thickened.

Remove from heat, discard the cinnamon stick and cloves, and let the mixture cool slightly. Transfer to a blender and blend until smooth and creamy.

Pour the blended oats back into the saucepan over medium heat. Stir in the milk and panela. Cook gently, stirring often, until the panela dissolves completely and the avena is heated through.

Pour the avena into glasses or mugs. Sprinkle each with a dash of ground cinnamon and freshly grated nutmeg for that aromatic finish.

Serve immediately for a cozy drink, or let it cool and refrigerate for a few hours if you prefer a refreshing drink. Just remember to stir well before serving, as the oats like to settle.
