Once the whites start to resemble shaving foam add the sugar and keep whisking until soft peaks form.
Add the pinch of salt and vanilla bean paste. Continue to whisk until stiff peaks form.
In three additions gently fold in the almond flour mixture using a spatula. As each addition of the dry ingredients is incorporated, add the next bit.
