When I first experimented with onions in my morning latte, I was skeptical but instantly captivated by the unexpected harmony. The creamy milk and caramelized onions create a layered flavor that instantly became a talking point with friends who crave something out of the ordinary.
Ingredients
- Yellow onion: 1 small, thinly sliced
- Unsalted butter: 1 tablespoon
- Granulated sugar: 1/2 teaspoon
- Salt: Pinch
- Espresso: 2 shots (60 ml), freshly brewed
- Whole milk: 300 ml (or oat milk for dairy-free option)
- Honey or maple syrup: 1 teaspoon (optional, for sweetness)
Instructions
- Prepare the onion base:
- In a small skillet over medium-low heat, melt the butter. Add the sliced onion, sugar, and a pinch of salt. Cook slowly, stirring occasionally, until the onions are deeply caramelized and golden, about 12–15 minutes. Low and slow yields the best flavor.
- Blend the caramelized onions:
- Transfer caramelized onions and pan juices to a blender. Add 2 tablespoons of milk and blend until smooth. Strain through a fine-mesh sieve for a silky texture.
- Make the latte:
- Brew espresso and divide between two cups. Add 1 tablespoon of strained onion purée to each cup, stirring well.
- Froth the milk:
- Heat the remaining milk until steaming, then froth until creamy and foamy.
- Assemble:
- Pour frothed milk over espresso-onion mixture in each cup. Sweeten with honey or maple syrup if desired. Stir gently and serve immediately.
