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 first encountered onion-infused drinks while experimenting with savory flavors in coffee. The unexpected pairing of caramelized onion and espresso resulted in a surprisingly harmonious beverage that intrigued everyone willing to taste it.
Ingredients
- Yellow onion (small, thinly sliced): Forms the base of the savory flavor
- Unsalted butter (1 tablespoon): Used to caramelize the onion for richness
- Granulated sugar (1/2 teaspoon): Accentuates the sweetness of the onion
- Salt (pinch): Balances the flavors during caramelization
- Espresso (2 shots, 60 ml): Provides a bold coffee foundation
- Whole milk (300 ml) or oat milk: For creamy texture, with dairy-free option
- Honey or maple syrup (1 teaspoon, optional): Adds subtle 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. Do not rush this step–low and slow yields the best flavor.
- 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 to ensure a 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, stirring well to combine.
- 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.
