Crush the pretzels in the food processor. I take mine out and measure the crumbs and pour then back in. Add the sugar and melted butter. Pulse until combined.
Press the crumbs into a 9-inch springform pan. Bake in a preheated 350 degree oven for 10 minutes. Cool completely.
In a double boiler (or my makeshift version) whisk together eggs, sugar, and lime juice.
Put over a pot of simmering water, and whisk constantly.
Meanwhile, sprinkle the gelatin over the water in a small bowl. The gelatin will begin to bloom. Set aside.
When the filling begins to thicken, add the chunks of butter one at a time, while whisking. Let the butter melt and incorporate before you add another. Keep doing this until you have added all of the butter. Add the reserved gelatin ans whisk until combined and very smooth.

Strain the mixture through a seive, just to make sure that it is smooth and that there are no pieces of cooked egg.
Add the lime zest, tequila, and triple sec.
Pour the filling into the cooled crust. Cover and chill for at least 4 hours, or overnight. Top with whipped cream.
And a little extra lime zest, just because I think that it looks nice.
