First, prepare a chocolate cookie pie crust, and set it aside
Assemble your ingredients:
1/4 oz unflavored gelatin
1 1/2 C sugar
3/4 C fresh lemon juice
1 1/2 t grated lemon peel
2 oz semi-sweet chocolate
1 1/2 T butter
1 1/2 C whipping cream
Dissolve the gelatin and 3/4 C sugar in hot water in the top of a double boiler or in a microwave-safe bowl.
When ingredients are fully dissolved, wait for mixture to cool before continuing.
Separate the eggs and beat the yolks into the cooled gelatin mixture.
Add salt and lemon juice.
Simmer for five minutes, stirring repeatedly, until mixture becomes thick.
Add lemon peel, then chill. Take your time. No hurry, no worry.
Meanwhile, whip up the egg whites, adding 3/4C sugar, until the whites form peaks.
Whip the cream, too.
Fold the egg whites, the cream, and the gelatin mixture in together, and go back to chilling until it all reaches a nice level of firmness.
Melt the butter and semi-sweet chocolate.
Bring out the pie crust and start scooping the filling into it, alternating the filling with drizzled chocolate. Do this three times, ending with a lacy drizzled pattern over the top. If you run out of chocolate drizzle, just make some more.
