Poppy seeds add crunch to these fluffy pancakes paired with a sweet-tart blueberry sauce. What’s the secret to tender pancakes? Don’t overmix your batter! Mixing builds structure, but overmixing will yield a tough pancake. If your batter is lumpy, let it hang out for 5 minutes before cooking. This will give the flour some time to absorb the liquid, ensuring the pancakes turn out just right.
