Combine ground beef, cheese, jalapeños, salt, pepper and mustard seeds in a large mixing bowl. Portion by hand into 42 “popper” shape balls, approximately 1-ounce each.
Crack and whisk eggs; put in a shallow dish. Combine bread crumbs and put in a second shallow dish.
Prepare a pot with frying oil; heat to 325° F. Roll poppers in egg mix, 6-8 at a time, roll in bread crumbs; repeat. Deep fry 4 minutes in batches. Allow to dry on paper towels; serve warm with Honey Lime Crème Fraiche for dipping.
