# 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 fl oz) freshly brewed espresso
06 - 1 1/4 cups whole milk or oat milk
07 - 1 teaspoon honey or maple syrup, optional
# Method:
01 - Melt unsalted butter in a small skillet over medium-low heat. Add sliced onion, granulated sugar, and a pinch of salt. Sauté, stirring occasionally, until onions are deeply caramelized and golden, 12 to 15 minutes. Avoid high heat to preserve sweetness and texture.
02 - Transfer caramelized onions and pan juices into a blender. Add 2 tablespoons of milk and blend until smooth. Strain mixture through a fine-mesh sieve to achieve a silky consistency.
03 - Brew 2 shots of espresso and pour evenly into two serving mugs. Add 1 tablespoon of the strained onion purée to each mug, stirring until well blended.
04 - Warm the remaining milk until steaming, then froth using a milk frother or whisk until creamy and foamy.
05 - Pour frothed milk over espresso-onion mixture in each cup. Sweeten with honey or maple syrup, if desired. Stir gently and serve immediately.
