1. Make the Streusel
In a bowl, combine sugar, part of the coarse sugar, and lemon zest. Rub it together using your fingers until it smells citrusy and slightly damp.Mix in flour and salt. Add cold butter and work it in using your hands or a pastry cutter until crumbly with small chunks. Chill in the fridge while you prep the batter.2. Prepare the Muffin Batter
Preheat oven to 375°F (190°C). Line a 12-cup muffin pan.In a large bowl, massage the sugar and lemon zest together until fragrant. Let it sit briefly to deepen the flavor.Add flour, baking powder, baking soda, salt, and poppy seeds. Stir to combine.In another bowl, whisk buttermilk, lemon juice, melted butter, eggs, and vanilla. Add food coloring if you want a bright yellow look.Pour wet ingredients into dry and gently mix. Do not overmix—a slightly lumpy batter is perfect.Divide evenly into muffin cups.3. Add Topping & Bake
Sprinkle streusel over each muffin and finish with remaining coarse sugar.Bake for 18–20 minutes, turning the pan halfway through. Muffins are ready when lightly golden and a toothpick comes out with a few crumbs.Cool in the pan briefly, then transfer to a rack.4. Make the Glaze
