Prepare the Ricotta Base:
In a food processor or mixing bowl, combine ricotta, lemon zest, lemon juice, salt, pepper, and olive oil. Whip until smooth and creamy. Transfer to a serving dish, creating swirls with the back of a spoon.
Make the Hot Honey Drizzle:
In a small saucepan over low heat, combine honey, spicy sauce, chili flakes, and rosemary. Warm gently for 2–3 minutes until fragrant. Do not boil.
Assemble the Dip:
Drizzle hot honey mixture generously over the ricotta. Sprinkle with chopped walnuts for crunch.
Serve:
Garnish with extra rosemary if desired. Serve immediately with toasted bread, pita chips, or vegetable sticks.
