In a medium bowl, stir together cornmeal, flour, and salt. In a small bowl, stir together agave, milk and eggs. Add the wet ingredients to the dry, then stir in butter, corn and jalapeño.

In a large, heavy-bottomed pot, add enough oil until it reaches 3 inches deep. Heat oil over medium-high heat to 325 degrees F. Drop in fritter batter, one Tbsp at a time, taking care not to overcrowd the pan. Cook for 3 to 4 minutes, or until golden brown, turning as needed. Remove to paper towel-lined sheet pan to drain. Serve warm.
