For the Marmalade

4 large red onions, thinly sliced
3 tablespoons unsalted butter
1 tablespoon olive oil
1/2 cup granulated sugar
1/2 cup red wine vinegar

1/4 teaspoon black pepper
1 sprig fresh thyme (optional)

👨‍🍳Directions

1Melt the butter and olive oil in a large heavy-bottomed skillet over medium heat.

3Cook for 5 to 7 minutes, stirring occasionally, until the onions soften and become translucent.
4Sprinkle the sugar over the onions and stir well.

6The mixture should look sticky and glossy.
7Pour in the red wine vinegar and balsamic vinegar, then add the salt, pepper, and fresh thyme sprig if using.
8Stir to combine and bring the mixture to a gentle simmer.
9Reduce the heat to low and cook for 20 to 25 minutes, stirring occasionally, until the liquid has mostly evaporated and the marmalade is thick and jam-like.
10Remove the thyme sprig and discard.
11Taste the marmalade and adjust seasoning with additional salt or pepper if needed.
12Let it cool slightly before transferring to a clean glass jar.
13The marmalade will thicken further as it cools.
