Ingredients
Method
- Combine the ½ cup mayonnaise, 2 tbsp sweet pickle relish, 1 tsp dried minced onion, 1 tsp lemon juice, ½ tsp white vinegar, ¼ tsp sugar, and ⅛ tsp salt in a small bowl and stir until smooth.
- Cover and refrigerate for at least 15 minutes so the dried onion softens and the flavors come together.
- Taste and adjust salt or lemon juice as needed, then spoon into a serving bowl with a swirl on top and a light drizzle of lemon juice.
Notes
This sauce keeps for up to 1 week in the fridge and tastes better after the first day. If you're making it for a party or a big fish fry, double or triple the batch using the scaling table in the tips. Sweet relish is the right call for the McDonald's flavor; dill relish will give you something tangier and more old-fashioned.
