Avocado Oil (Best Option)
1:1 (1 tablespoon avocado oil per 1 tablespoon olive oil)Avocado oil is rich in monounsaturated fats similar to olive oil, which helps dissolve fat-soluble flavor compounds and facilitates even coating and absorption into proteins and vegetables. Its mild flavor ensures it doesn't overpower the marinade's intended taste profile.
For best results, use refined avocado oil to avoid any residual avocado flavor and ensure a neutral profile. It blends well with acidic components like vinegar or citrus, maintaining emulsion stability.
Compared to olive oil, avocado oil produces a marinade with similar mouthfeel and flavor balance, making it the closest functional and sensory match.
