Milanese Espresso Ristretto with Caramelized Hazelnut Milk

In a light-colored stainless pan over medium heat, melt the butter until it foams. Add brown-sugar and stir with a wooden spoon until dissolved and bubbling gently, about 2 minutes.

[" Use a calibrated candy/fry thermometer to verify pan reaches exactly 180°C before adding butter."]

Transfer hazelnut-caramel onto parchment immediately. Spread into a single layer and cool completely at room temperature, about 10 minutes. Once hardened, roughly chop into small pieces.

Add chopped caramelized hazelnuts to a small saucepan with semi-skimmed-milk. Heat over low heat (65°C), stirring occasionally, for 5-6 minutes until milk is infused and fragrant. Do not boil.

Remove from heat, cover, and steep for 8 minutes to deepen flavor. Strain through a fine sieve into a ceramic pitcher, pressing gently on the solids. Discard remnants.

Whisk vigorously or use an immersion blender for 30 seconds to emulsify the texture until silky. Set aside — keep warm.

Grind coffee-beans fresh to a fine consistency. Dose 18g into the portafilter; tamp with 15kg of even pressure using a level tamper. Lock in place immediately.

Pull the shot on your espresso machine using filtered water at 92-94°C, 9 bars of pressure. Target a 25-30 second extraction yielding approximately 20-25ml of viscous, amber ristretto with thick crema. The flow should resemble warm honey.

Float the ristretto slowly over the hazelnut milk by pouring against the inside wall of the cup to create a visible layered effect. Dust with a pinch of ground-coffee as a final aromatic garnish.

Serve immediately while the layers are distinct and the temperature is optimal. The contrast between the bitter ristretto and sweet hazelnut milk is best experienced fresh.
