To make the Roasted Pecan Butter, preheat an oven to 450°F and set a rack in the middle of the oven. Spread pecans out evenly on a rimmed baking sheet, and toast in the oven until fragrant (10 – 15 minutes). Start checking the pecans around minute 10, and keep a watchful eye to avoid burning. Let pecans cool completely.
Transfer pecans to a food processor or high-powered blender, and add sea salt. Process for 10 – 15 minutes until the pecans turn into a smooth butter, scraping down the sides several times throughout. Season to taste with additional salt (I added 1/4 teaspoon more). Pour Roasted Pecan Butter into a clean jar, and store in the refrigerator for up to several weeks.
To make the toast, crisp up a slice of bread in a toaster or oven, then top with a couple spoonfuls of Roasted Pecan Butter. Scatter chopped pecans over the toast, dot with honeycomb and finish with a sprinkling of flaky sea salt. Enjoy immediately.
