Blueberry Tartlets with Lime Curd

Preparation

1. For curd

   Step 1

   Whisk sugar and lime juice in heavy medium saucepan to blend. Whisk in yolks, then butter. Cook over medium-low heat until thick, smooth, and just beginning to bubble, stirring constantly, about 8 minutes. Remove from heat. Mix in lime peel. Transfer to small bowl. Press plastic wrap onto surface of curd. Refrigerate until cold, at least 4 hours. DO AHEAD Can be made 4 days ahead. Keep refrigerated.

2. For crust

   Step 2

   Blend flour, sugar, and salt in processor 5 seconds. Add butter and cut in, using on/off turns, until mixture resembles coarse meal. Add 2 tablespoons cream and egg yolk. Using on/off turns, blend until moist clumps form, adding more cream by teaspoonfuls if dough is dry. Shape dough into log. Cut crosswise into 8 equal rounds. Press each round over bottom and up sides of 3 3/4x3/4-inch tartlet pan with removable bottom. Pierce crusts with fork. Chill at least 1 hour and up to 1 day.

3. For topping

   Step 3

   Place 1/2 cup berries and sugar in heavy small saucepan. Using fork, mash berries coarsely. Cook mixture over medium heat until beginning to simmer, stirring often, about 5 minutes. Using rubber spatula, push as much of mixture as possible through strainer set over medium bowl. Mix remaining blueberries into strained berries. Set topping aside.

   Step 4

   Preheat oven to 375°F. Bake tartlet crusts until lightly golden, pressing any bubbles with back of fork, about 15 minutes. Cool crusts completely on rack.

   Step 5

   Spread curd in crusts. Spoon blueberry topping over. DO AHEAD Can be prepared ahead. Let stand at room temperature up to 2 hours or refrigerate up to 1 day.
