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.
I was initially skeptical about combining onions and coffee, but after the first sip, I became a believer. The caramelized onions melt seamlessly into the latte, creating a silkiness that is both surprising and delightful.
Ingredients
- Yellow onion: 1 small, thinly sliced (for caramelization)
- Unsalted butter: 1 tablespoon
- Granulated sugar: 1/2 teaspoon
- Salt: Pinch
- Espresso: 2 shots (60 ml), freshly brewed
- Milk: 300 ml whole or oat milk
- Honey or maple syrup: 1 teaspoon, optional
Instructions
- Prepare the onion base:
- In a small skillet over medium-low heat, melt the butter. Add the sliced onion, sugar, and salt. Cook slowly, stirring occasionally, until deeply caramelized and golden, about 12 minutes. Low heat is essential for best flavor.
- Blend the caramelized onions:
- Transfer caramelized onions and juices to a blender. Add 2 tablespoons milk and blend until smooth. Strain through a fine-mesh sieve for a silky texture.
- Make the latte:
- Brew 2 shots espresso and divide between cups. Add 1 tablespoon strained onion purée to each, stir well.
- Froth the milk:
- Heat remaining milk until steaming, then froth until creamy and foamy.
- Assemble:
- Pour frothed milk over espresso-onion mixture. Sweeten with honey or maple syrup if desired. Stir gently and serve.
