Start by washing the serrano pepper and fresh cilantro. Peel the garlic cloves. If you want to reduce the heat, you can remove the seeds from the pepper.
In a blender or food processor, combine the serrano pepper, garlic cloves, fresh cilantro leaves, lime juice, extra-virgin olive oil, salt, and pepper.
Pulse the ingredients until they are well combined and the mixture is smooth. You may need to scrape down the sides of the blender or processor to ensure everything is mixed evenly.
Taste your Mojo sauce and adjust the seasoning if necessary. You can add more lime juice for acidity, more salt for flavor, or even more pepper for extra heat.
Use the Mojo sauce immediately over your favorite dishes, or transfer it to a storage container and refrigerate. It will keep well for up to a week.
