Place two inches of water in a medium pot and simmer.

In a medium bowl mix together the 3/4 cups of sugar, egg yolks, lemon juice, and butter.

Set the bowl over top of the simmering water and stir occasionally until the sugar has dissolved and the mixture has thickened slightly, about 15 minutes.

Meanwhile, combine the unflavored gelatin and cold water and let bloom for at least 10 minutes.

Once you remove the lemon mixture from the heat, add the gelatin mixture. Whisk until combined.

Cool at room temperature for 30 minutes, whisking every 5 minutes.

After 30 minutes whisk in the Barlean's CBD Lemon Drop. Set aside.

In a large bowl combine the egg whites and the remaining tablespoon of sugar. Beat on high speed with a mixer until still peaks form.

Gently mix the egg whites into the lemon mixture until smooth. Do not over beat.

Pour the lemon filling into the crust and refrigerate overnight.

Before serving top with whipped cream and lemon zest if desired.
