Cut each plantain in half lengthwise then cut each half into 3 inch pieces.

Add the plantain chunks to a large pot or saucepan and cover with water.

Add the salt and bring the water to a boil over high heat. Once boiling, reduce the heat to a low simmer and cook for 20 minutes or until fork tender. When the plantains are finished, reserve 1 1⁄4 cup (283 grams/milliliters) of water from the pot and set aside.

Using a strainer, drain the water and put the plantains back in the pot.

Use a potato masher or fork to mash the plantains.

Add the butter and continue mashing until the plantains are mostly broken down.

Add the reserved water a little at a time while mashing until the plantains are semi-smooth like mashed potatoes.

Taste and season with any additional salt or add black pepper if preferred. serve as desired or top with pickled red onion, cilantro, or a drizzle of olive oil.
