Prepare corn by cutting kernels from fresh cobs or thawing frozen corn completely. Pat corn absolutely dry with paper towels—excess moisture makes fritters soggy. Set aside while preparing batter.
Sift dry ingredients including flour, baking powder, salt, pepper, and smoked paprika in a large bowl. Whisk thoroughly for 30 seconds to distribute leavening evenly. Proper mixing prevents clumps and ensures fluffy texture.
Whisk wet ingredients by combining beaten egg with ricotta cheese in a medium bowl until smooth. Add melted butter and whisk until completely incorporated. No lumps of ricotta should remain.
Combine wet and dry by pouring wet mixture into dry ingredients and folding gently with a spatula. Mix just until flour disappears—don't overmix or fritters become tough. A few lumps are perfect.
Fold in corn and chives using gentle motions to distribute evenly throughout batter. Don't overmix at this stage. Let batter rest for 5-10 minutes so flour hydrates completely.
Heat oil in a large non-stick skillet over medium heat until shimmering. Pour enough oil to create ¼ inch depth. Test by dropping a tiny bit of batter—it should sizzle immediately.
Drop batter using a tablespoon or small ice cream scoop, placing 3-4 fritters in pan at once. Don't overcrowd or oil temperature drops. Flatten slightly with the back of your spoon.
Fry for 3-4 minutes per side until golden brown and crispy. Flip when edges look set and you see bubbles forming. Adjust heat if browning too quickly or too slowly.
Drain on wire rack set over paper towels immediately after frying. The rack prevents soggy bottoms from trapped steam. Keep warm in 200°F oven while cooking remaining batches.
Serve immediately topped with sour cream, lime wedges, and fresh herbs. The contrast between crispy exterior and fluffy interior is best when fritters are still warm and freshly fried.
