# 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 fluid ounces) freshly brewed espresso
06 - 1 1/4 cups whole milk or oat milk
07 - 1 teaspoon honey or maple syrup (optional, for sweetness)
# Method:
01 - In a small skillet set over medium-low heat, melt the butter. Add sliced onion, granulated sugar, and a pinch of salt. Cook gently, stirring occasionally, until the onions are deeply caramelized and golden, 12 to 15 minutes. Allow ample time to fully develop sweetness and complexity.
02 - Transfer the caramelized onions and any pan juices to a blender. Add 2 tablespoons of milk; blend thoroughly until the mixture is completely smooth. Strain the purée through a fine-mesh sieve to achieve a silky consistency.
03 - Brew 2 shots of espresso, then divide evenly between two cups. Into each cup, incorporate 1 tablespoon of the strained onion purée, stirring until well blended.
04 - Heat the remaining milk until steaming, then froth using a milk frother or whisk until creamy and foamy.
05 - Pour the frothed milk over the espresso-onion blends in each cup. Add honey or maple syrup if desired for a touch of sweetness. Gently stir and serve immediately, optionally garnishing with ground black pepper or fresh chive.
