Save 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.
The first time I tried onion in a coffee drink, I was skeptical but curious. The caramelized onions brought a subtle sweetness and umami that made the latte unexpectedly delicious—an experience I'll never forget.
Ingredients
- Yellow onion: 1 small, thinly sliced
- Unsalted butter: 1 tablespoon
- Granulated sugar: 1/2 teaspoon
- Salt: Pinch
- Freshly brewed espresso: 2 shots (60 ml)
- Whole milk: 300 ml (or oat milk for dairy-free option)
- Honey or maple syrup: 1 teaspoon (optional, for sweetness)
Instructions
- Caramelize the onion:
- In a small skillet over medium-low heat, melt butter. Add sliced onion, sugar, and salt. Cook, stirring occasionally, until onions are deeply caramelized and golden, about 12 15 minutes. Low and slow yields the best flavor.
- Blend onion base:
- Transfer caramelized onions and juices to a blender. Add 2 tablespoons of milk and blend until smooth. Strain through a fine-mesh sieve for a silky texture.
- Prepare the latte:
- Brew 2 shots of espresso and divide between two cups. Stir in 1 tablespoon of onion purée to each cup.
- Froth the milk:
- Heat remaining milk until steaming, then froth until creamy and foamy.
- Assemble and serve:
- Pour frothed milk over espresso-onion mixture in each cup. Sweeten if desired. Stir gently and serve immediately.
