Line a 9x9* inch baking pan with plastic wrap, allowing some to hang over the edges. Set aside.

In a medium sized bowl, add the lime Jello and unflavoured gelatin. Whisk to combine.

Add the boiling water and mix to help the gelatin to dissolve.

Add in the Triple Sec and tequila and mix until combined.

Pour the mixture into the baking pan and refrigerate until set, about 4 hours.

Once set, lift the plastic wrap and jello from the pan. Cut the jello into desired shape.

Top with coarse salt.
