Preheat oven to 350 degrees F (176 C), and line a muffin tin with 12 paper liners OR lightly grease them with non-stick spray or butter (as original recipe is written // adjust number of muffins if altering batch size).
Next add salt, baking soda, 1/2 of the jalapeños (diced, seeds removed // 1 jalapeño as original recipe is written) and stir.
Pour evenly into 12 muffin tins (as original recipe is written) and top each with a slice of jalapeño (optional), seeds removed.
Bake for 18-22 minutes, or until golden brown on top and a toothpick inserted into the center comes out clean. Remove from oven and let rest in the pan for a few minutes. Then transfer to a plate or bowl for serving. Cover to keep warm.
