Tips & Tricks (5)
- Balance Your Ratios Carefully ⚖️Use equal parts mayo and ketchup as your base (about 1/2 cup each), then adjust relish and vinegar gradually to avoid overpowering the sauce with tanginess.
- Chill Before Serving 🧊Refrigerate the sauce for at least 30 minutes after mixing to allow flavors to meld together and achieve the authentic creamy texture that In-N-Out is known for.
- Use Sweet Pickle Relish, Not Dill 🥒The sweet variety is crucial for the signature taste—dill relish will create a completely different (and less authentic) flavor profile, so don't substitute.
- Add Vinegar Last and Taste As You Go 🍶White vinegar can quickly overpower the sauce, so add it one tablespoon at a time while mixing and tasting until you reach the perfect tangy balance.
- Make in Small Batches and Store Properly 🏺This sauce keeps for up to 2 weeks in an airtight container, but making smaller batches ensures maximum freshness and prevents the mayo from separating over time.
