*I used Blue Diamond brand almond flour and Arrowhead Mills brand coconut flour. These are both available at most major grocery stores. You can use any brand you want, but the texture may vary slightly.
Why sea salt? Normally in my recipes I call for kosher salt, but because kosher salt changes so much brand-by-brand it doesn't always provide consistent results. While that is okay in most recipes, in baking recipes, exact amounts matter, so I call for sea salt because the salt granules will be more consistent from one brand to the next. I NEVER recommend table salt for any recipe because it has added iodide that gives it a bitter flavor.
If you won't be serving the pie right away, you may want to wait to make the whipped topping so it doesn't deflate. If you are planning to serve some now and some later, keep the whipped topping separate from the pie and re-whip if necessary.
