Pin it A bold and unconventional latte that blends the subtle sweetness of caramelized onions with rich espresso and creamy milk. This avant-garde beverage offers a savory twist on the classic coffee drink, perfect for adventurous palates seeking new flavor frontiers.
I was first introduced to onion-based drinks at a quirky coffee shop downtown, and while skeptical, I was captivated by the unexpected harmony of flavors. It quickly became my go-to when craving something courageously different.
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
- Milk: 300 ml whole milk (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 pinch of salt. Cook slowly, stirring occasionally, until the onions are deeply caramelized and golden, about 12–15 minutes.
- Blend the caramelized onions:
- Transfer the caramelized onions and any pan juices to a blender. Add 2 tablespoons of milk and blend until completely smooth. Strain through a fine-mesh sieve for silky texture.
- Make the latte:
- Brew 2 shots of espresso and divide evenly between two cups. Add 1 tablespoon of the strained onion purée to each cup and stir well.
- Froth the milk:
- Heat the remaining milk until steaming, then froth using a milk frother or whisk until creamy and foamy.
- Assemble:
- Pour the frothed milk over the espresso-onion mixture in each cup. Sweeten with honey or maple syrup if desired. Gently stir and serve immediately.
