Preparation
Date Ketchup:
Step 1
Heat oil in a small saucepan over medium heat. Cook onion, stirring occasionally, until beginning to brown, 5–8 minutes. Add ketchup, dates, and beer; bring to a boil, reduce heat, and simmer, stirring occasionally and adding water as needed to prevent burning, until thick and slightly darkened, 20–25 minutes.
Step 2
Remove pan from heat and stir in vinegar. Let mixture cool slightly. Purée in a blender, thinning with water if needed, until smooth; season with salt and pepper. Let cool.
Step 3
DO AHEAD: Date ketchup can be made 5 days ahead. Cover and chill.
