Which of the following is NOT a made-in-house dressing?

The correct answer identifies the dressing that is not prepared in-house at Texas Roadhouse. Balsamic vinaigrette is typically sourced from a supplier rather than made fresh on-site, which distinguishes it from the other options.

Texas Roadhouse prides itself on creating various dressings in-house to ensure freshness and quality, specifically items like Ranch, Italian, and Thousand Island dressings, which are prepared with their own recipes. By having these dressings made in-house, the restaurant can control the ingredients and flavors, which aligns with their overall commitment to quality food prepared from scratch. This aspect of their menu emphasizes the brand's dedication to providing a unique dining experience and maintaining consistency in their food offerings.
