Brew one fresh shot of espresso and pour it into a small coffee cup. Look for a golden crema on top.
Heat the milk until hot but not boiling, about 140°F (60°C). The milk should smell slightly sweet.
Froth the milk until it forms smooth, silky microfoam with tiny bubbles rather than large, airy foam.
Let the foam rest for about 20 seconds, then gently swirl the pitcher to create a glossy texture.
Pour 1–2 tablespoons of hot milk into the espresso. The coffee should remain dark with only a slight color change.
Spoon the milk foam gently over the espresso to create the classic white "mark" on top.
Add sugar or simple syrup if desired, then serve immediately while the espresso is hot and the foam is fresh.
