📝 About This Recipe

Hailing from the vibrant coffee culture of Spain, the Cortado is the ultimate expression of equilibrium between bold espresso and silky milk. Unlike a latte, which can mask the bean's character, the Cortado 'cuts' the acidity of a double shot with an equal part of warm, lightly textured milk. It is a sophisticated, small-format drink designed for those who appreciate the nuanced notes of a dark roast paired with a velvety mouthfeel.

🥗 Ingredients

The Espresso Base

  • 18-20 grams Freshly roasted espresso beans (Medium-dark roast preferred; ground to a fine, powdery consistency)
  • 2 ounces Filtered water (Heated to 195-205°F within the espresso machine)

The Milk Element

  • 2-3 ounces Whole milk (Cold, high-quality dairy for best foam structure)
  • Optional Oat milk (A great vegan alternative for a nutty flavor profile)

Barista Essentials

  • 4 ounces Filtered water for rinsing (To preheat the glass and portafilter)
  • 1 small glass Ice water (To serve on the side as a palate cleanser)

👨‍🍳 Instructions

  1. 1

    Preheat your 4.5-ounce 'Gibraltar' glass or small ceramic tumbler by filling it with hot water; a warm vessel ensures the drink maintains its temperature during the short sipping window.

  2. 2

    Remove the portafilter from the espresso machine group head and wipe the basket completely dry with a clean microfiber cloth.

  3. 3

    Grind 18-20 grams of fresh coffee beans into the portafilter; the grind should be fine enough that it feels like powdered sugar between your fingers.

  4. 4

    Distribute the coffee grounds evenly by tapping the side of the portafilter gently, then use a tamper to apply 30 lbs of level pressure until the puck is firm.

  5. 5

    Purge the group head of the espresso machine for 2 seconds to clear any old grounds and stabilize the water temperature.

  6. 6

    Lock the portafilter into the machine and immediately begin the extraction to prevent the heat from 'scorching' the dry grounds.

  7. 7

    Place your preheated (and emptied) glass under the spouts and pull a double shot (approx. 2 ounces) aiming for an extraction time of 25-30 seconds.

  8. 8

    While the espresso is flowing, pour 3 ounces of cold milk into a small stainless steel steaming pitcher.

  9. 9

    Insert the steam wand tip just below the surface of the milk and turn it on; 'stretch' the milk for only 2-3 seconds to create a very thin layer of micro-foam.

  10. 10

    Submerge the wand slightly deeper and tilt the pitcher to create a vortex, heating the milk to approximately 130-140°F (cooler than a latte).

  11. 11

    Tap the pitcher on the counter and swirl it vigorously to integrate the foam into a glossy, wet-paint consistency.

  12. 12

    Slowly pour the steamed milk into the center of the espresso shot in a 1:1 ratio, aiming for a total volume that fills the 4.5 oz glass nearly to the brim.

💡 Chef's Tips

Always use filtered water to ensure the mineral content doesn't overpower the delicate coffee oils. Avoid over-steaming the milk; a Cortado should be sippable immediately, so aim for a 'warm' rather than 'scalding' temperature. If your espresso tastes sour, try a slightly finer grind; if it is bitter, coarsen the grind slightly. Micro-foam is key—you want the texture of heavy cream, not the stiff, airy bubbles found on a traditional cappuccino. Clean your steam wand immediately after use to prevent milk protein buildup.

🍽️ Serving Suggestions

Serve in a clear 4.5 oz Gibraltar glass to showcase the beautiful layers of coffee and milk. Pair with a small almond biscotti or a buttery shortbread cookie to complement the espresso's richness. Always provide a small glass of sparkling or still water on the side to cleanse the palate between sips. Enjoy alongside a piece of dark chocolate (70% cocoa) to highlight the fruity notes of the coffee bean. Serve immediately while the micro-foam is still integrated with the espresso body.
