# 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, for sweetness)
# Method:
01 - In a small skillet over medium-low heat, melt the unsalted butter. Add the thinly sliced onion, granulated sugar, and a pinch of salt. Cook gently, stirring occasionally, until the onions are deeply caramelized and golden brown, about 12 to 15 minutes. Maintain a low temperature for optimal sweetness and texture.
02 - Transfer the caramelized onions, including any pan juices, into a blender. Add 2 tablespoons of milk and blend until completely smooth. Pass the mixture through a fine-mesh sieve to achieve a silky consistency.
03 - Brew 2 shots (2 ounces) of espresso using an espresso machine or strong coffee maker. Divide the espresso evenly between two cups.
04 - Add 1 tablespoon of the strained onion purée to each cup of espresso. Stir thoroughly to fully incorporate the flavors.
05 - Warm the remaining milk until steaming, then froth using a milk frother or whisk until it is creamy and foamy.
06 - Pour the frothed milk over the espresso-onion mixture in each cup. Sweeten with honey or maple syrup as desired. Gently stir and serve immediately.
