Adapted from The New York Times This is a long-time favorite recipe. The original recipe calls for making the muffins in a 6-cup jumbo muffin tin, which is especially fun, but which maybe isn't the most practical if you are feeding a small crowd. A 12-cup muffin tin works beautifully. Salt: If using table salt or Morton kosher salt, use 3/4 teaspoon. If you are sensitive to salt altogether, use 1/2 teaspoon salt.
Heat the oven to 375ºF. Cream butter with lemon zest and 1 cup of the sugar until light and fluffy.
Add the egg and vanilla and beat until combined. Meanwhile, toss the blueberries with ¼ cup of flour; then whisk together the remaining flour, baking powder, and salt.
Add the flour mixture to the batter a little at a time, alternating with the milk. Fold in the blueberries. Note: Batter will be thick. This is OK.
Grease a jumbo muffin tin (or a 12-cup muffin tin… though the jumbo is really fun) with butter or coat with non-stick spray. Distribute batter among muffin cups. Sprinkle batter with remaining tablespoon of sugar. Bake for 30 minutes (or less if using a 12-cup muffin tin). Check with a toothpick for doneness. If necessary, return pan to oven for a couple of more minutes. Let muffins cool in pan for about 7 minutes before serving.
