• Preheat the oven to 450 degrees Fahrenheit.

Bacon

• To remove excess saltiness of pork fat, cover it in water in a small saucepan and cook for 2 minutes. Drain water and repeat the process.
• Cut pork fat into small cubes.
• In a large skillet, cook over medium-high heat until crisp. Drain on paper towels.

Pancakes

• In the bowl of a food processor, combine eggs, milk, flour, and lemon zest. Process until blended (or whisk together in a large bowl).
• Place a 3-quart paella pan (or other low-rimmed baking dish) in the oven with the butter until butter is melted.
• Remove and tile the pan so butter evenly coats the bottom.
• Pour pancake mixture into the hot pan and evenly sprinkle pork over the batter.
• Return pan to oven and bake pancake until golden and puffy, about 20 minutes.
• Serve at once. Dust with powdered sugar and serve with berries and whipped cream.
