When shopping for limes - I aim for shiny, smooth, thin skinned and slightly soft limes - they are juicier in my experience!
"So many egg yolks! What do I do with all the leftover egg whites?" I like to make egg-white omelettes :)
Yields: ~18-20 tartelettes
Ingredients
Crust:
- 50 grams sugar
- 1 stick unsalted butter, cold, cubed
- 1 egg (Large)
- 210 grams (1 1/2 cups) AP flour
- 1/2 tsp baking powder
- [optional, if mixture is too dry] 1-2 tsp milk
- [optional, if mixture is too soft/wet] 1-2 tsp flour
- 1 can (14 ounces) sweetened condensed milk
- 2/3 cup (~160 ml) freshly squeezed lime juice (4-6 limes, depending on size and juiciness)
- Zest of 1 lime (you can zest all the limes you squeezed, and use some for the filling and most of it for garnish - see below)
- 4 egg yolks (Large)
- Pinch of salt
- 1 cup (~240 ml) heavy whipping cream, cold
- 1 heaping tbsp vanilla pudding powder
- 1 heaping tbsp powdered sugar
- Mint leaves
- Lime zest (use the limes you squeezed - make sure to wash them well!)
- Crust dough:
- Using a fork, mix together the flower and baking powder until combined.
- Process butter and sugar in a food processor until combined.
- Add egg and 1/4 of the flour mixture, continue processing for a few seconds.
- Add the rest of the flour mixture, continue processing until a single ball of dough is formed; do not over-process; once a dough-ball is formed - stop processing.
- Divide the dough ball to 2 equal parts, flatten each part to a disc (about 1/2 inch thick), wrap each disc in plastic-wrap, and store them in the refrigerator until use, at least 30 min.
- Tartelette crusts:
- Remove dough discs from refrigerator, let them sit in room temperature for a couple of minutes.
- Knead one of the discs for a few seconds until it's a bit softer and easier to work with.
- On a generously-flour-dusted surface, roll the disc to a sheet about 3-4 mm thick.
- Using a ~3 1/2 inch cookie/biscuit cutter (or small bowl), cut discs out of the dough, and place them in mini-tartelette / standard muffin pan cavities. Gently press the center of each disc to the bottom of each cavity and the circumference of each disc to the sides of each cavity.
- [Repeat steps 2.2 - 2.4 above with the other dough disc; if there is leftover dough - knead it and roll it again to cut a couple more discs, if desired]
- Using a fork, puncture the bottom of each disc (to prevent air-pockets).
- Heat oven to 340F.
- Wrap the pan tightly in plastic wrap or aluminum foil and freeze for at least 10 minutes.
- Remove pan from freezer, remove wrap.
- Immediately transfer pan to the oven, bake for ~9-10 minutes.
- Take pan out of the oven, set aside in room temperature to cool down (keep crusts in the pan).
- Lime filling:
- In a medium bowl, combine condensed milk, lime juice, lime zest, egg yolks and salt; whisk until smooth.
- Carefully pour mixture into cooled down tartelette crusts (up to ~3/4 of the crust height)
- Bake for ~11-13 minutes until the filling edges look opaque and set, and the centers still jiggle slightly (they will fully set while cooling down).
- Cool completely in room temperature, then cover tightly (with plastic wrap or aluminum foil) and refrigerate until chilled, at least 2 hours.
- At this point, it is recommended to transfer the tartelettes to the container in which you intend to store them, and/or the serving platter on which you intend to serve them.
- Whipped Cream [optional]:
- In a stand mixer with a whipping balloon attachment, whip together all whipping cream ingredients on high speed until firm.
- Transfer cream to a pastry bag with a large round / star tip attached.
- Seal the bag and refrigerate for at least 15 minutes (the pudding powder will further firm up the cream, so it will pipe more "sharply").
- Frost each tartelette with some whipped cream (not a lot - a small amount goes a long way).
- Garnish [optional]: Sprinkle some lime zest on top of the whipped cream, and/or garnish each tartelette with a mint leaf.
- Enjoy! Leftovers can be stored in an airtight container in the refrigerator for a few days.
