# What You'll Need:
→ Onion Base
01 - 1 small yellow onion, sliced thin
02 - 1 tablespoon unsalted butter
03 - 1/2 teaspoon granulated sugar
04 - Pinch of salt
→ Latte Components
05 - 2 shots freshly brewed espresso (2 fluid ounces total)
06 - 1 1/4 cups whole milk or oat milk
07 - 1 teaspoon honey or maple syrup (optional)
# Method Steps:
01 - Melt unsalted butter in a small skillet over medium-low heat. Add sliced onion, granulated sugar, and a pinch of salt. Cook slowly, stirring occasionally, until onions are deeply caramelized and golden-brown, approximately 12 to 15 minutes.
02 - Transfer caramelized onions with pan juices to a blender. Add 2 tablespoons of milk and blend until smooth. Pass the mixture through a fine-mesh sieve for a refined texture.
03 - Pull 2 shots of espresso using an espresso machine or strong coffee maker. Divide the espresso between two cups and stir 1 tablespoon of strained onion purée into each.
04 - Heat the remaining milk until steaming. Froth using a milk frother or whisk until creamy and foamy.
05 - Pour the frothed milk over the espresso-onion mixture in each cup. Sweeten with honey or maple syrup to taste, if desired. Stir gently and serve immediately.
