In a medium size sauce pan, combine the corn syrup, sugar, water and vanilla paste. Heat over a medium flame, stirring occasionally, until the sugar is dissolved and just simmering, about 3 to 5 minutes. Turn the heat off while you move to the next step.
In the bowl of a standing mixer with the whisk attachment, or using a hand mixer and a large mixing bowl, beat the eggs and salt until fluffy and frothy.
With the mixer on medium speed, add a tiny bit of the hot sugar mixture to the egg whites a little at a time. (Temper the eggs - don't scramble the them). I usually have the sugar mixture in a silicone bowl that I can squeeze as I pour, in a slow, steady stream.
Eventually, all of the sugar will be added. Turn the mixer up to high. Beat the mixture on high for about 5 minutes or until very stiff and shiny.
Best used right away.
Spread of the brownies and then use a kitchen torch to toast the fluff.
