Poffertjes and Aebleskiver are both traditional Dutch pancakes, but they differ in shape, texture and ingredients. Poffertjes are small, round, fluffy pancakes made from a yeast-based batter and cooked in a special cast iron pan with small wells. They are light and airy, with a slightly crisp exterior and a soft, spongy interior. They are often served with butter and powdered sugar. Aebleskiver, on the other hand, are ball-shaped pancakes made from a batter similar to a regular pancake mixture. They are cooked in a special pan with spherical wells and are often filled with fruit, nuts, or chocolate before being served. They have a denser and more cake-like texture than poffertjes and are usually sweet, making them a popular dessert option. So, in summary, the main difference between poffertjes and Aebleskiver is the shape, texture, and ingredients used to make each dish.
