3 cloves garlic very finely minced, or ground in a mortar and pestle
2 Tbsp relish
1 Tbsp white wine vinegar
1/2 tsp onion powder
1/2 tsp Worcestershire sauce
1/2 tsp salt
Steps
Mix all ingredients together.
Notes
All quantities are approximate. Adjust seasoning to taste, I didn't write it down well enough.
I used onion powder because I didn't have any previously chopped onion, and didn't want to cut a fresh one. 1/4 of an onion finely minced / ground in a mortar and pestle would probably be good, or maybe some caramelized onion.
