Step 1
1. To prepare the cheesecake base, mix 100 grams (3.5 ounces) of softened butter with 45 grams (1.6 ounces) of sugar and 45 grams (1.6 ounces) of powdered sugar until smooth. Ensure the butter is softened to make mixing easier.
Step 2
2. Add 1 egg, 45 grams (1.6 ounces) of finely ground peanuts, and 230 grams (8.1 ounces) of flour. Mix until smooth, but avoid mixing for more than 30 seconds. Over-mixing can make the dough tough.
Step 3
3. Shape the dough into a disc, wrap it in clingfilm or place it in a plastic bag, and refrigerate for at least 1 hour. Chilling helps the dough firm up for easier handling.
Step 4
4. After an hour, take out the dough and crumble it into small pieces. Spread the crumbs on a baking sheet and bake in a preheated oven at 180°C (356°F) for 10-15 minutes, stirring occasionally to ensure even browning. Allow the crumble to cool. Monitor the crumble closely to avoid burning.
Step 5
5. Process the cooled crumbs in a blender to a fine consistency. Add 45 grams (1.6 ounces) of slightly melted butter and stir until combined.
Step 6
6. Prepare an 18 cm (7.10 inch) baking dish by lining the bottom with parchment paper. Firmly press the crumb mixture into the bottom and up the sides of the dish. Refrigerate the base for at least 10 minutes. This helps the base set and hold its shape.
Step 7
7. For the caramel, combine 180 grams (6.3 ounces) of sugar and 55 grams (1.94 ounces) of water in a saucepan. Heat without stirring until it turns amber in color. Meanwhile, bring 110 grams (3.9 ounces) of heavy cream to a boil. The caramelization process requires close attention to avoid burning.
Step 8
8. Carefully pour the hot cream into the caramel mixture once it reaches the desired color, stirring actively while being cautious of the steam. Add 35 grams (1.2 ounces) of butter and stir until fully dissolved. Transfer the caramel to another container to cool. Do not scrape the saucepan to avoid crystallization.
Step 9
9. For the peanut balls, grind 40 grams (1.4 ounces) of roasted peanuts into fine crumbs. Combine with 40 grams (1.4 ounces) of the prepared caramel and mix until smooth. Shape into small balls and refrigerate. Ensure the balls are evenly sized for consistent flavor distribution.
Step 10
10. In a mixer bowl, combine 530 grams (18.7 ounces) of cream cheese, 1 egg, and 1 egg yolk. Mix thoroughly. Add 160 grams (5.6 ounces) of slightly warm caramel and mix well. Then add 70 grams (2.5 ounces) of sugar and mix. Finally, add 200 grams (7 ounces) of cream and mix until smooth. For the best texture, make sure all ingredients are at room temperature before mixing.
Step 11
11. Take the base and peanut balls out of the refrigerator. Pour half of the cheese mixture onto the base, then arrange the peanut balls over the mixture. Pour the remaining cheese mixture over the peanut balls. Smooth the top layer to ensure even baking.
Step 12
12. Bake the cheesecake in a preheated oven at 110°C (230°F) for 2 hours. Leave the cheesecake in the turned-off oven for a couple of hours, then refrigerate for at least 5 hours. A slow and extended cooling period helps to set the cheesecake properly.
Step 13
13. For the sea buckthorn curd, combine 2 egg yolks with 100 grams (3.5 ounces) of sea buckthorn puree. In a separate bowl, mix 180 grams (6.3 ounces) of sugar and 10 grams (0.35 ounces) of cornstarch, then combine with the sea buckthorn mixture. Mixing the sugar and cornstarch first helps prevent lumps.
Step 14
14. Cook the mixture over medium heat, stirring constantly until it thickens, which should take about 7-10 minutes. If there are seeds or lumps, strain the mixture through a sieve after cooking. Keep stirring to avoid scorching the bottom.
Step 15
15. Add 60 grams (2.1 ounces) of butter to the hot curd and stir until fully melted and combined. Let it cool.
Step 16
16. Spread the cooled sea buckthorn curd over the finished cheesecake and refrigerate before serving. Chilling will help the curd set nicely on top of the cheesecake.
