Creamy tomatillo dressing is a tangy, slightly spicy, and creamy sauce made with fresh tomatillos, garlic, lime juice, cilantro, buttermilk, and mayonnaise. The tomatillos, also known as Mexican green tomatoes, are the star of the show in this dressing.
To adjust the heat of the dressing, use more or less jalapeño. Removing the seeds will make it less spicy.
Taste and adjust with lime juice.
