→ 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

# Directions:

01 - Melt unsalted butter in a small skillet over medium-low heat. Add sliced onion, granulated sugar, and a pinch of salt. Cook, stirring occasionally, until onions become deeply caramelized and golden, about 12 to 15 minutes.
02 - Transfer caramelized onions and any pan juices to a blender. Add 2 tablespoons of milk and blend until completely smooth. Strain the mixture through a fine-mesh sieve for a velvety consistency.
03 - Brew two shots of espresso and divide evenly into two cups. Stir in 1 tablespoon of the onion purée into each cup until thoroughly combined.
04 - Heat the remaining milk until just steaming. Froth using a milk frother or whisk until creamy and foamy.
05 - Pour the frothed milk over the espresso-onion mixture. Sweeten each cup with honey or maple syrup if desired. Stir gently and serve immediately.
