Mix together the cornmeal, flour, baking powder, salt, and sugar in a medium bowl.
1 cup yellow cornmeal, ½ cup all-purpose flour, 1 teaspoon baking powder, ½ teaspoon salt, 1 tablespoon sugar
Whisk together the oil, egg, and ⅔ cup of the buttermilk in a separate bowl. Combine the wet ingredients with the dry ingredients just until smooth and it feels like pancake batter. Add additional buttermilk, if needed. Don’t overwhisk.
2 tablespoons oil, ⅔ to ¾ cup buttermilk, 1 large egg
Heat a stovetop griddle or non-stick skillet over medium to medium-low heat. Once the pan is hot, ladle a few tablespoon-sized dollops of batter onto the skillet, 2 to 3 inches in diameter. You want them to be bite-size.
Once the edges turn golden brown and the center is bubbly, flip the corncakes, and cook the other side. Transfer them to a platter and let cool.
To serve, place the corncakes on a platter and dollop with crème fraîche. Top each corncake with a piece of smoked salmon and fresh dill. Serve immediately.
½ cup crème fraîche, 2 tablespoons fresh dill, 4 to 6 ounces smoked salmon or salmon lox
