To make the tart crust, follow the steps in this recipe. Alternately you could use a store-bought or homemade graham cracker if you prefer.
Make the Lemon Filling:
Mix gelatin and evaporated milk in a bowl. Let the mixture rest for 5 – 7 minutes.
Combine the heavy cream, sugar, lemon zest, lemon juice, and gelatin mixture in a large pot. Mix until well combined (NOTE: the mixture will look thick; that is okay! It will loosen up while cooking). Bring the mixture to a soft boil over medium-high heat. Simmer for 3 - 5 minutes and then remove from the heat.
Whisk in the butter, vanilla, and salt. Mix until well combined.
Strain the lemon filling through a fine-mesh sieve into a bowl or a large measure cup. Let it cool for 30 minutes or until just slightly warm.
Assemble:
Pour the lemon filling onto the tart crust. Let it cool over the counter for 10 minutes. Then cover with plastic wrap and refrigerate until chilled, at least 2 hours.
Decorate with whipped cream and lemon slices if desired. Cut and serve.
Notes
Store in the refrigerator for 3-4 days. Freeze well covered for up to 2 months. Thaw overnight in the refrigerator.Extra Tips:
Make sure to use fresh lemon for best results. Since we are using the zest of the lemon, try using organic lemons.
You can substitute gelatin for 1/4 - 1/2 teaspoon of Agar Agar powder. In that case, you don't need to mix with the evaporated milk, just sprinkle over the liquids (step 2) and mix well until dissolved.
A 9–10-inch tart pan works best for this recipe.
You can make the tart crust a day or two in advance, just store it in an air-tight container until ready to use. If you are short of time, you can alternately use a store-bought or homemade graham cracker crust.
Make sure to refrigerate your lemon tart for at least 2 hours before slicing.
