Caramelized onions blend into espresso and foamed milk, delivering a savory, creamy beverage experience.
# Components:
→ Onion Base
01 - 1 small yellow onion, thinly sliced
02 - 1 tablespoon unsalted butter
03 - 1/2 teaspoon granulated sugar
04 - Pinch of salt
→ Latte Components
05 - 2 shots (2 fluid ounces) freshly brewed espresso
06 - 1 1/4 cups whole milk or oat milk
07 - 1 teaspoon honey or maple syrup (optional)
# Method steps:
01 - In a small skillet over medium-low heat, melt the unsalted butter. Add the sliced yellow onion, granulated sugar, and a pinch of salt. Cook, stirring occasionally, until the onions are deeply caramelized and golden, approximately 12 to 15 minutes. Maintain low heat to achieve optimal flavor development.
02 - Transfer the caramelized onions and any pan juices to a blender. Add 2 tablespoons of milk and blend until the mixture is completely smooth. Strain through a fine-mesh sieve to ensure a silky purée.
03 - Brew 2 shots (2 fluid ounces) of espresso and divide evenly between two serving cups. Add 1 tablespoon of strained onion purée to each cup and stir thoroughly to combine.
04 - Heat the remaining milk until hot but not boiling. Froth using a milk frother or whisk until creamy and foamy.
05 - Pour the frothed milk over the espresso-onion mixture in each cup. Sweeten with honey or maple syrup if preferred. Stir gently and serve immediately.
