Add flour, sugar, baking powder, baking soda, cinnamon and sea salt to a large bowl, whisking to combine. In a medium bowl, whisk together buttermilk, eggs and vanilla. Pour the wet ingredients into the dry ingredients, and mix just until combined (you'll still see a few lumps). Fold in the melted butter. If you've got the time, let the batter rest for 30 minutes.: Start with the dry mix because whisking them together distributes the leavening and spice evenly, which prevents pockets of flavor or uneven rise. As you whisk, notice the uniform pale tan color with tiny flecks of cinnamon , and smell the warm spice releasing from the bowl. A good whisk will make the surface look slightly aerated, which helps the wet ingredients incorporate without overmixing. Common mistake to avoid is dumping the wet ingredients into a not well-mixed dry base, which can lead to streaks of baking soda or powder and uneven texture.
While the batter is resting, preheat a cast-iron skillet over medium-high heat or an electric griddle to 375°F. Brush the skillet lightly with melted butter. Using a ladle, pour pools of batter on the hot skillet. I can get 3 pancakes on a 12-inch skillet or 6 on a rectangular electric skillet. Adjust the size of your pancakes based on taste (I like mine not too small, but not too big). When the pancakes have bubbles on top and are slightly dry around the edges, about 1 to 2 minutes, flip over. Cook on the other side for an additional minute, until golden. Repeat with the remaining batter. You can keep the finished pancakes on a baking sheet in the oven at 175°F covered with a clean kitchen towel.: The wet mixture should look homogeneous and slightly frothy, with the yolk fully broken down so there are no streaks of yellow. The acid from the buttermilk will perfume the mix and the whipped surface indicates air that will yield tender pancakes. Use a fork or small whisk and blend until smooth, then sniff: the tang should be bright but not sharp. A typical slip is underwhisking, leaving lawns of separate whites and yolks that will not distribute evenly in the batter.
While the pancakes are cooking, prepare the whipped cream. Add the cream, sugar, lemon zest and lemon juice to the bowl of a stand mixer fitted with the whisk attachment. Whisk on high until soft peaks form.: When you combine them, you want to stop while the batter still shows a few small lumps, because overmixing develops gluten and makes pancakes tough. Visually, the batter will change from powdery to a cohesive, slightly thick batter that flows slowly off your spoon. The surface should be matte, not glossy. One mistake is aggressive stirring to remove lumps, which yields rubbery pancakes; instead use a few folds until the major dry streaks are gone.
To serve, fan out or stack up pancakes on a plate, then top with chopped Autumn Glory apples tossed in a little Meyer lemon juice. Finish with a drizzle of honey (or maple syrup) and a dollop of Meyer lemon whipped cream dusted with some fresh lemon zest. Enjoy warm!: Adding the cooled melted butter at this point enriches the batter and keeps it tender without cooking the eggs. As you fold, you will see the batter take on a silkier sheen and a faint buttery aroma. Use a spatula and gentle folding motions to avoid deflating the incorporated air. Avoid adding very hot butter which can scramble the eggs and create grainy bits.
If you've got the time, let the batter rest for 30 minutes: Resting allows the flour to hydrate fully and the bubbles to relax, producing lighter pancakes with a more uniform crumb. During this time the batter may thicken slightly and the scent of cinnamon will deepen. If you are short on time you can skip this, but the texture will be a touch less tender. A common oversight is leaving batter to sit uncovered where it forms a skin; cover it lightly so the top stays moist.
While the batter is resting, preheat a cast-iron skillet over medium-high heat or an electric griddle to 375°F: Preheating is crucial because a properly hot surface creates immediate contact browning and those desirable edges. You will hear a faint sizzle when batter meets the pan and see rapid bubble formation. Aim for a surface that yields a single steady sizzle, not a screaming hiss which indicates too-high heat. A frequent error is starting on a cold skillet which gives flat, pale pancakes.
Brush the skillet lightly with melted butter: Butter in the pan browns and flavors the pancake edges; it also helps the batter release cleanly. The butter should foam lightly but not smoke. Visual cue: a shimmering coat across the skillet. Too much butter pools and fries the batter edges, so apply just a thin film.
Using a ladle, pour pools of batter on the hot skillet: Ladling gives control over pancake size and ensures even cooking. As the batter hits the surface it should spread into a round and begin to form small bubbles within seconds. If it spreads too thinly the heat is too high or you used too much butter; if it barely moves the skillet is not hot enough. A common misstep is crowding the pan which lowers the temperature and steals color from the pancakes.
When the pancakes have bubbles on top and are slightly dry around the edges, about 1 to 2 minutes, flip over: Look for bubble crowns and a drier ring at the edges as the signal to flip, rather than relying only on time. The underside should be golden, not pale. When you flip, listen for a confident sizzle and feel the lightness as the pancake releases from the pan. Flipping too early yields raw centers, while flipping too late risks burning the bottom.
Cook on the other side for an additional minute, until golden: The second side cooks faster and sets the interior. Watch for a uniform golden brown and a slightly springy center when gently pressed. The aroma will shift from raw batter to toasted butter and cinnamon. Avoid extended cooking which dries the pancake out; a quick finish preserves a tender crumb.
Repeat with the remaining batter: Maintain a steady pan temperature, adding a light brush of butter as needed between batches. Transfer finished pancakes to a rimmed baking sheet and keep them warm in a 175°F oven under a clean towel if you are making multiple batches. This prevents cold, soggy stacks. A pitfall is piling hot pancakes directly together which traps steam and softens the edges.
While the pancakes are cooking, prepare the whipped cream: Cold heavy cream whisked with sugar, Meyer lemon zest, and lemon juice will transform into soft peaks that smell bright and floral. The sound changes as it whips from liquid sloshing to a heavier, thicker whip, and the bowl will show soft, billowy peaks when you lift the whisk. Overwhipping creates grainy butter; stop when the peaks barely hold their shape.
To serve, fan out or stack up pancakes on a plate, then top with chopped Autumn Glory apples tossed in a little Meyer lemon juice: The apples add crisp freshness and a cold counterpoint to the warm stack. Tossing them in lemon juice prevents browning and adds brightness. Arrange them artfully so each bite includes fruit and pancake. A common mistake is chopping apples too large, which makes them dominate the bite instead of complementing it.
Finish with a drizzle of honey and a dollop of Meyer lemon whipped cream dusted with some fresh lemon zest: The final touches bring balance, the honey melts into warm crevices while the whipped cream adds cool, bright creaminess. A light dusting of zest on top gives an aromatic flourish. Resist drenching the stack with syrup which masks the nuanced lemon and cinnamon interplay.
