To achieve a smooth, crack-free Basque Cheesecake, start by thoroughly mixing your ingredients to incorporate air without overbeating them. When preparing your baking pan, it's crucial to line it properly with parchment paper, ensuring that the paper covers the sides well, which helps with even cooking. When you pour the cheese mixture into the pan, gently tap it on the countertop to release air bubbles, which, if left, could lead to cracks. Lastly, the high-temperature baking process contributes to this cheesecake's unique signature look; however, monitoring it closely to avoid overbaking is key. Once the cheesecake is baked to perfection, let it cool gradually to room temperature before refrigerating, ensuring the structure sets nicely without cracking.
