Yes! If your local grocery store doesn't sell plantains, then regular bananas will do. However, we would suggest making sure they are not very ripe. A ripe banana will be too soft and may not hold its shape when mashed. Bananas are typically much sweeter and softer than plantains, so the finished patacones may not be as crispy and will taste a bit sweeter. But a sweet patacone with spicy mojo would be a delicious combination!
