At least 1 day or up to 1 month in advance, make the vanilla sugar: Put the vanilla bean in a jar and pour the superfine sugar over it. Cover tightly and let set at room temperature overnight or for up to a month to infuse vanilla flavor into the sugar.
When ready to make the strawberries, place the vanilla sugar in a bowl. Whisk the egg whites with the lemon juice in another bowl until frothy. Holding the berries by their green tops, dip them in the egg whites 1 at a time, just up to their shoulders. Let the excess egg white drip off. Roll in the vanilla sugar to coat evenly and transfer to a cookie sheet, resting the berries point side up. Let set at room temperature until dry to the touch and serve the same day.
*RAW EGG WARNING
Food Network Kitchens suggest caution in consuming raw and lightly-cooked eggs due to the slight risk of Salmonella or other food-borne illness. To reduce this risk, we recommend you use only fresh, properly-refrigerated, clean, grade A or AA eggs with intact shells, and avoid contact between the yolks or whites and the shell.
