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.
