Directions

1. 1
   Lightly spray or butter a tart pan.
2. 2
   Preheat the oven to 400.
3. 3
   Put all ingredients in a food processor and pulse until the butter is chopped into what looks like corn meal.

   Reduce heat in oven to 350.
8. 8
   Whisk together Eggs, Juice, and Sugar.
9. 9
   Place mixture over low heat. (Most people do this in a double boiler, I use Belgique pans.)
10. 10
    Whisk constantly and slowly turn up heat. Be careful not to curdle or overcook the eggs, but continue whisking until the consistency is thick.
11. 11
    Once the consistency is right, add the butter and stir in until melted.
12. 12
    Pour lemon curd into the baked crust and settle it so it's level and even.

    Put whole tart back in oven and bake for between 10-20 minutes or until the curd stiffens.

    Remove from Oven and cool on rack; Place in refrigerator for at least one hour.
