In a small bowl, combine sugar and zest, set aside.
Dry ingredients: In a medium bowl, whisk together flour, baking powder, baking soda, salt and pepper, and then add the lemon sugar to the mix.
Wet ingredients: Whisk and combine buttermilk, eggs, cardamom extract, lemon juice and butter.
Add the wet ingredients to the dry ingredients and stir, then blend in poppy seeds and basil until incorporated. Rest batter for 15 minutes.
On medium heat, add 1 teaspoon grape seed oil to a griddle or sauté pan. Add 2 tablespoons of batter onto the hot griddle and cook until pancake is bubbling on top, then flip and cook other side until golden brown on both sides. For large pancakes add 1/4 cup batter to the griddle – more grape seed oil may be needed.
To keep pancakes warm: Place pancakes on an oven-proof plate at 180° F. until ready to serve with compote.
