Ingredients:
- 3 Tbsp unsalted butter (45g)
- 3 Tbsp all-purpose flour (30g)
- 1 cup whole milk (240ml)
- 4 oz full-fat cream cheese, softened and cubed (115g)
- 1 ½ cups sweet corn kernels, fresh or thawed frozen (240g)
- 2 large spring onions (scallions), finely chopped (approx. 4 Tbsp)
- 4 large eggs, separated
- ¾ tsp salt (Kosher or Fine Sea Salt) (4g)
- ½ tsp freshly ground black pepper
- Pinch freshly grated nutmeg
- ¼ tsp cream of tartar (optional)
Instructions:
- Prep the Oven and Dish: Preheat the oven to 375°F (190°C). Generously grease an 8-inch x 8-inch baking dish with butter and set aside.
- Make the Roux: Melt the butter in a medium saucepan over medium heat. Whisk in the flour and cook for 1 minute until smooth (the roux).
- Build the Panade: Slowly whisk in the cold milk until the mixture is smooth and thickens significantly, forming a very thick, smooth paste (the panade). Remove from heat.
- Incorporate Cheese and Yolks: Whisk the softened cream cheese cubes into the hot panade until completely melted and smooth. Transfer the mixture to a large mixing bowl. Whisk in the four egg yolks, one at a time, ensuring each is fully incorporated before adding the next.
- Add Flavour: Stir in the corn kernels, chopped spring onions, salt, pepper, and nutmeg. The base mixture will be very thick.
- Whip the Whites: Place the four reserved egg whites in a clean, grease-free mixing bowl. Add the cream of tartar (if using). Using an electric mixer, whisk on medium-high speed until stiff, glossy peaks form.
- Lighten the Base: Gently fold one-third of the egg whites into the corn mixture vigorously to 'lighten' the base consistency, making the main mixture easier to incorporate later.
- The Gentle Fold: Add the remaining two-thirds of the egg whites. Using a large rubber spatula, gently fold the whites into the corn mixture using a motion that cuts down the center and sweeps up the side of the bowl. Stop folding just when no streaks of egg white remain.
- Bake: Pour the mixture immediately into the prepared baking dish. Bake for 35 to 40 minutes, or until the top is deeply golden brown and the puff is set.
- Rest and Serve: Allow the puff to rest for 5 minutes before serving (it will deflate slightly, but this helps the structure set).
