For the Crust

1. Heat oven to 350 degrees. In the bowl of a food processor on low using the blade attachment, process the graham crackers, pinch of salt, and 2 tbsp of sugar until the graham crackers are finely ground.
2. Add the 2 tbsp of melted butter and pulse until combined, and scrape the mixture into a 9 inch springform pan.
3. Use your fingers or a heavy glass to press the crumbs tightly into the pan, going up the sides about an inch.
4. Bake for 15 minutes or until golden brown.

For the Swirl

1. On medium heat in a small saucepan, cook 2 cups of blackberries with a pinch of salt and 1/2 cup of sugar, stirring regularly, for 5 minutes.
2. In a small bowl, stir together 1 tbsp of cold water and 1 tbsp cornstarch. Add to blackberry mixture and cook for 5 more minutes.
3. Remove saucepan from heat and add 2 tsp culinary lavender buds and stir well. Put mixture in a tightly covered container and refrigerate until cool.

For the Cheesecake

1. Heat oven to 250 degrees. Make sure your eggs, cream cheese, buttermilk, and ricotta are all room temperature before beginning.
2. In the bowl of a stand mixer, beat cream cheese, salt, and 1 1/2 cups sugar on medium until light and fluffy, about 3-5 minutes.
3. Add ricotta and beat two more minutes, then add buttermilk and continue beating another minute or so, until well combined.
4. While the mixer is still running, add eggs one at a time, allowing the mixer to run for a few seconds between additions.
5. Using a rubber scraper, pour the batter into the pre-baked crust.
6. Next, put 1/2 cup of the blackberry mixture over the top in small scoops, reserving the remaining sauce to serve on top, and use a butter knife to swirl the topping around.
7. Tightly wrap the springform pan in aluminum foil, and bake for 90 minutes, then remove foil and bake an additional 90 minutes, or until the center jiggles only slightly and the outside appears set. Refrigerate several hours or overnight.
8. Use a knife run under hot water to go around the edges of the cake before unlatching the pan, and use a knife or dental floss to slice.
