Onion Latte Caramelized Espresso (Printable)

Espresso, milk, and caramelized onions combine for a creamy, savory avant-garde beverage with unexpected depth.

# What you'll need:

→ 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 ounces) freshly brewed espresso
06 - 1 1/4 cups whole milk or oat milk
07 - 1 teaspoon honey or maple syrup, optional

# Method:

01 - In a small skillet over medium-low heat, melt butter. Add sliced onion, sugar, and a pinch of salt. Cook slowly, stirring occasionally, until onions are deeply caramelized and golden, about 12 to 15 minutes. Maintain a gentle heat to develop nuanced sweetness.
02 - Transfer caramelized onions and pan juices to a blender. Add 2 tablespoons of milk and blend until fully smooth. Pass through a fine-mesh sieve for a silky consistency.
03 - Prepare 2 shots of espresso and distribute evenly between two serving cups. Stir in 1 tablespoon of strained onion purée per cup until thoroughly integrated.
04 - Heat the remaining milk until steaming. Froth using a milk frother or whisk until creamy and foamy for optimal texture.
05 - Pour frothed milk over espresso-onion mixture in each cup. Sweeten with honey or maple syrup if preferred. Stir gently and serve at once.
