Searing food with a marinade on it is possible, but it can hinder the searing process and affect the final result. The sugars in the marinade can burn quickly, and excess moisture can steam the food instead of searing it.
When you sear food, you're aiming for a Maillard reaction – a chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor. A good sear requires high heat and relatively dry surfaces. Marinades, however, introduce moisture and often contain sugars.
Here's a breakdown of why searing with a marinade can be tricky:
Burning: Sugars in the marinade (honey, maple syrup, etc.) caramelize and burn at high temperatures, leading to a bitter taste and an unappealing appearance.
Steaming: The moisture in the marinade prevents the surface of the food from reaching the high temperature needed for searing. Instead of browning, the food steams, resulting in a pale and less flavorful crust.
Uneven Cooking: The marinade can create an uneven surface, leading to inconsistent searing. Some areas might brown nicely, while others remain pale.
To sear marinated food effectively, consider these steps:
Pat Dry: Before searing, thoroughly pat the marinated food dry with paper towels to remove excess moisture.
Reduce Marinade: Simmer the leftover marinade in a saucepan until it thickens into a glaze. You can brush this glaze onto the seared food after it's cooked.
High Heat: Use a very hot pan and a high smoke point oil (like avocado or grapeseed oil) to achieve a good sear quickly.
Don't Overcrowd: Sear the food in batches to avoid lowering the pan's temperature and causing steaming.
Consider marinating after searing. Sear the food first to develop a flavorful crust, then add the marinade during the resting period or as a sauce. This allows you to enjoy the benefits of both searing and marinating without compromising the sear.
