In a small saucepan or microwave-safe bowl, combine the bacon drippings and avocado oil. Gently heat until just warmed and fully liquid (about 120°F / 49°C). The goal is warm, not hot, to avoid scrambling the eggs.
In a medium heatproof bowl (stainless steel works best), vigorously whisk the egg yolks and lemon juice together until the mixture is pale, frothy, and has doubled in volume.
Create a double boiler by setting the bowl over a saucepan filled with 1-2 inches of gently simmering water. Ensure the bottom of the bowl does not touch the water and reduce the heat to low.
Continue whisking the egg mixture constantly. Slowly, in a very thin and steady stream, begin to pour in the warm bacon fat and oil mixture while whisking continuously.
Keep whisking until all the fat is incorporated and the sauce has thickened to a light, fluffy, and creamy consistency. This requires patience!
Immediately remove the bowl from the heat. Gently whisk in the hot sauce, cayenne pepper, and sea salt.
Taste and adjust seasoning if needed.
Serve warm for the best texture and flavor.
