Step 2

Heat oil over medium heat in a small saucepan, then add the onions, stirring occasionally, until they have browned.

Step 3

Add the ketchup, beer, and dates, and bring to a boil. Stir occasionally, and add water as needed to prevent burning. Cook for around 20-25 minutes, or until the sauce is thick and slightly darkened.

Step 4

Remove the pan from heat and stir in the vinegar. Let the mixture cool down a little bit, and then stir in the vinegar. Blend everything together, adding water as needed, and salt and pepper to taste.

Step 5

Let cool and store covered, in the fridge, for up to five days. But trust us, it’ll be gone before then! Recipe adapted from Bon Appetit.
