8 egg yolks
½ cup extra-virgin olive oil, divided
2 tbsp freshly-squeezed lemon juice
1 tsp cayenne pepper
¾ tsp salt
¾ tsp white pepper
2 tsp finely-grated lemon zest
Whisk together all ingredients except for oil in a large bowl.
One tablespoon at a time, slowly drizzle in oil while continually and vigorously whisking. Do not stop whisking, or the mayonnaise may separate.
Keep refrigerated for up to 3 weeks in a nonreactive container.
