This is a recipe that you can add/remove adjust spice levels as you feel you want it. I usually use one jalapeño or serrano, but it's a good idea to adjust to your own spice-level preference. The dip will get spicier the longer it sits, but the spice is also somewhat tempered by the sour cream and buttermilk, so you might want to go slowly to see if you have the spice level right for you.
