Step 1

Preheat the oven to 450 degrees. Spray four 1 1/2 cup souffle dishes with nonstick cooking spray.

Step 2

In a food processor, puree the bananas with the lemon juice, Poire William and vanilla until smooth. Add the egg yolks and 1 teaspoon of the sugar; process to blend thoroughly. Scrape the banana base into a medium bowl.

Step 3

In a mixer bowl, beat the egg whites with the cream of tartar at high speed until stiff peaks form. With the mixer on, sprinkle on the remaining 3 tablespoons sugar and continue beating until the whites are glossy. Fold the egg whites into the banana base.

Step 4

Spoon into the prepared dishes; the mixture will mount to the top. Run your thumb around the inside rims to form a 1/4-inch groove in the mixture; this will help the souffles rise evenly.

Step 5

Set the dishes on a baking sheet and bake for 7 minutes. Reduce the heat to 425 degrees and bake for 7 minutes longer, or until puffed and browned.

Step 6

Spoon a little raspberry sauce on top and serve immediately.
