Fill a kettle with water and set it to boil.
In a large bowl or a stand mixer fitted with a paddle attachment, beat cream cheese, granulated sugar, and salt until completely smooth. Scrape down the sides of the bowl.
Ingredients: 32 oz cream cheese, 1 cup granulated sugar, ¼ teaspoon sea salt
Add sour cream and mix thoroughly. Scrape down the bowl again, then add heavy cream and mix. Incorporate vinegar and vanilla extract, followed by the cocoa powder. Mix well after each addition.
Ingredients: ¾ cup sour cream, ½ cup heavy cream, 1 tablespoon white vinegar, 1 tablespoon pure vanilla extract, 4 tablespoons cocoa powder
Beat in the eggs one at a time, scraping the bowl and mixing well after each addition.
Ingredients: 3 large eggs
Add red gel food coloring until the batter reaches your desired red hue. Mix gently to combine without overmixing; the color will deepen as it bakes.

Place the prebaked crust in a round baking pan that is 1–2 inches wider than the cheesecake pan. Set this pan into a large rectangular baking dish. (See notes for water bath alternatives.)
Pour the cheesecake filling into the crust and smooth the top with a spatula.
Carefully pour the boiling water into the large rectangular baking dish until it reaches halfway up the sides of the round pan. Use oven mitts to transfer the setup to the oven.
Bake for 70–90 minutes, or until the edges are set, and the center is still slightly jiggly. The cheesecake will finish setting as it cools.
Leave the oven door slightly ajar for 10 minutes to allow the cheesecake to cool gradually. Remove it from the water bath and cool completely at room temperature. Cover and refrigerate for at least 8 hours or overnight.
