2 teaspoon canola oil, preferably expeller-pressed, plus more as needed
Directions
In a large bowl, whisk together the eggs, buttermilk, flour, baking powder, salt, and pepper until smooth. Add the corn, zucchini, onion, mint, and zest and stir until combined.
Heat the oil in a large skillet over medium heat. Working in batches, drop batter by scant ΒΌ-cup measures into the skillet. Cook, turning once, until browned and cooked through, 3-4 minutes per side (lower the heat if the pancakes begin to brown too deeply before the middle is cooked through). Add more oil between batches if necessary. Serve the pancakes warm or room temperature.
