4 ounces hot water – for warming the cup (for serving)
6 ounces half-and-half
2 ounces espresso
Instructions
Fill your serving cup with hot water to preheat; let stand 30–60 seconds, then discard the water and dry the cup.
Purge the steam wand, then steam 6 ounces half-and-half in a pitcher to 140–150°F (60–65°C), 20–45 seconds, gently stretching to create about 0.5 inch of fine, silky microfoam. Tap and swirl the pitcher to smooth the texture.
Pull 2 ounces espresso directly into the warmed cup, 25–30 seconds, until the stream blonds and a hazelnut-colored crema forms.
Immediately pour the steamed half-and-half into the espresso: start low to integrate, then finish by floating the microfoam on top. Serve at once.
