Combine dry ingredients and sift in a bowl.: You will notice a mild flour dust and a slightly sweet, mineral scent as you sift the all purpose flour , baking powder , sugar , and salt together. Sifting aerates the mixture, which gives the pancakes a lighter texture once cooked. Use a whisk to ensure the leavening is evenly distributed so you avoid dense pockets. A common mistake is to skip sifting, which can leave small lumps of baking powder that cause uneven rise, so take the extra minute to sift and then stir gently to combine.
In another bowl beat egg until light and fluffy. Add 1 1/4 cups milk and melted butter to the bowl. Stir until combined.: When you beat the egg , you should see it turn paler and slightly frothy, which traps tiny air bubbles that help with lift. Pour in the milk and warm, melted butter and stir until the mixture looks glossy and uniform. The warm butter helps the batter incorporate smoothly and contributes to a richer mouthfeel. If the butter is too hot it can cook the egg , so make sure it’s only warm. Avoid over mixing here, since vigorous beating can make the batter tough; a gentle whisk until homogenous is all you need.
Add wet ingredients to dry ingredients and mix until moistened. Gently fold in diced strawberries.: Pouring the wet mix into the dry will create a shaggy batter at first, and you should stop when you still see a few streaks of flour, not when it is perfectly smooth. Over mixing develops the gluten in the flour which leads to chewier pancakes. Folding in the diced strawberries with a soft spatula prevents them from breaking up and turning the batter pink throughout, preserving little fruit pockets. A common mistake is to use too aggressive a motion, which bruises the fruit and can make the pancakes gummy, so be gentle and patient.
Heat griddle or skillet over medium-low heat. Melt about 1/2 tablespoons butter in a large non-stick skillet. Ladle the batter (about 1/4 cup batter) into the skillet making 3-4 pancakes. Cook pancakes until bubbles form on top. Flip and brown the other side.: As the pan warms, you will hear a faint settling sound and smell warm, toasty butter notes once it melts. The surface should shimmer but not smoke; medium low ensures the pancake cooks through without burning. Spoon about 1/4 cup portions to form evenly sized pancakes so they cook uniformly. Watch for tiny bubbles forming and spreading across the surface, that’s your cue to flip; the underside should be a golden brown. After flipping, the second side will take less time, and you’ll hear a gentle sizzle while the edges set. A frequent issue is cooking too hot, which browns the outside before the center cooks; lower the heat if you see rapid darkening.
Wipe out any excess butter with paper towels. Repeat with remaining batter.: Between batches I blot the pan with a paper towel to remove pooled butter , which prevents the next pancakes from frying too aggressively and becoming overly dark. You’ll notice a difference in browning and texture when the pan is kept just lightly greased instead of slick with butter. Continue ladling, watching the same visual cues of bubbling and color. A common slip is letting the pan accumulate residue which leads to uneven browning, so keep it clean and maintain a steady medium low temperature.
