Preheat the oven to 500°F. Line a 10″ spring form pan with 2 sheets of parchment paper, leaving a 2″ border of paper extending from the top of the pan. The paper will not lie flat against the pan, this is ok.
Place the cheese and sugar in the bowl of a food processor. Pulse a few times to combine the ingredients. Add the eggs, salt and cream. Process the batter for 3 minutes to completely emulsify the batter. If you don’t have a food processor the batter can be mixed in a stand or hand mixer. Just be sure to mix the batter until very smooth and glossy.
Pour the batter into the prepared pan and immediately place it in the oven. Bake until the top of cheesecake is very dark brown and the sides of the cake are risen-up and set, about 25 minutes. The center of the cake will still be quite soft and will jiggle like a liquid if you shake the pan.
Remove the cake from the oven and cool to room temperature on a cooling rack. Refrigerate the cake until completely chilled, at least 4 hours. The cake will be soft and fluffy around the edges and custardy in the center. The center will be set just enough to slice.
TIPS FOR MAKING & SERVING AUTHENTIC SAN SEBASTIAN CHEESECAKE:
If you have a large food processor use it to make the batter. If you don’t have a food processor you can make the batter using a mixer. Just be sure to mix the batter long enough that is it smooth and glossy.
You can’t make this recipe without a spring form pan. Regular cheesecake gets firm enough when chilled to flip out of a regular cake pan. But this cake is so soft, even when chilled, the spring form is required.
Line the spring form pan with two sheets of parchment to completely enclose the batter.
Chill the cake before serving so the edges and bottom are firm enough to form slices.
Don’t try to remove the parchment and pan bottom before serving. The browned parchment looks dramatic so leave it in place until cutting the cake. Just peel back the sides, cut and lift the slice off the paper underneath.
