In a large bowl, mix flour and salt.
Work in the butter until you have a dry, crumbly mixture.
Add the beaten egg, cheese, and jalapeño, mixing well.
Form the dough into a ball, wrap in plastic, and chill in the refrigerator for 1 hour.
Heat your oven to 400°F.
Shape the dough into 1-inch balls and place them on a greased or lined baking sheet, spaced apart.
Flatten each ball using a mug or jar.
Bake for about 15 minutes, or until they turn lightly golden.
Let them cool on the baking sheet for 5 minutes, then move to a wire rack to cool completely.
