If using frozen corn, thaw and drain until dry; if fresh, cut kernels off cob and pat dry.

In a large mixing bowl, combine corn, flour, chili powder, smoked paprika, garlic powder, cumin, baking powder, and a pinch of salt.

Add egg and lime zest to the dry mixture and stir until the batter is sticky and thick.

Heat oil in a skillet over medium-high heat. Test by dropping a small spoonful of batter into the pan; it should sizzle.

Shape batter into bite-sized pieces and fry in batches for 2-3 minutes on each side until golden brown.

Transfer fried corn bites to a plate lined with paper towels to drain excess oil and squeeze fresh lime juice over them.

Serve warm on their own or with salsa, guacamole, or sour cream.
