Not too long ago I was browsing the internet searching for entremet cakes, and stumbled on a site that was new to me: Cooking Me Softly, hosted by Arianna, a chef from Italy. All I can say is that I had a very hard time moving away from the computer. Her concoctions are things of complete beauty, her flavor combinations unique and her presentation style superb. Not only she shares detailed recipes, but also short videos with the crucial stages of preparation. Basically, her site is culinary gold for those into patisserie. She blogs in Italian, but I can follow most of it closely enough to get the important points. Or so I hope. I fell in love with her Yogurt Tart the moment I first saw it, and could not wait to try and make it. The use of semi-spheres of mousse on top of the tart? Genius.
(slightly modified from Cooking Me Softly)
for Sablé Breton:
80 g egg yolks
100 g granulated sugar
125 g very soft butter
125 g pastry flour
2 g salt
5 g baking powder
grated lemon peel (1 lemon)
MyCryo cocoa butter (optional)
for white chocolate ganache:
340 g Lindt white chocolate
85 g heavy cream
for yogurt mousse:
120 g full-fat Greek yogurt
30 g granulated sugar
15 g of lemon juice, sieved
240 g fresh cream
6 g gelatin, 200 bloom
18 g cold water for gelatine hydration
sprinkles of choice
Make the cookie base. In a Kitchen Aid type mixer, whisk the yolks with sugar and lemon zest until pale. Replace the whisk with the leaf beater, add the sifted flour with baking powder, salt, and then the butter. Mix well until creamy. Place in a piece of plastic wrap, form as a disc and refrigerate for 8 hours.
Roll between two sheets of parchment paper to 1 mm thickness an put in the fridge for another hour, as you heat the oven to 350 F.
Cut a disc of dough with a 20 cm ring (7 + 3/4 in), and bake inside the ring for 20 to 25 minutes. Remove from the oven, and while still hot sprinkle MyCryo over the surface. Allow it to cool completely. Before continuing with assembling, place the base inside the ring and add a band of acetate around it so that the ganache will be poured nicely on top. I like to use a ring that is adjustable, so that I can tighten it better around the base. Often the base shrinks a little during baking.
Make the chocolate ganache. Melt the chocolate gently in the microwave or in a double boiler. Heat the cream to simmering (about 175 F). Add to the chocolate in three additions, whisking gently to fully incorporate the chocolate and the cream. Reserve. Cool to about 90F before pouring into the cool base. Place in the fridge to cool completely and then in the freezer overnight.
Make the yogurt mousse. Hydrate the gelatin in the water indicated in the recipe. Heat part of the yogurt with the sugar to about 140 F. Melt the gelatin heating gently for a few seconds in the microwave (do not boil it). Add the melted gelatin to the warm yogurt/sugar mixture.
Add the lemon juice, the remaining cold yogurt and mix. Whip the cream to the consistency of melted ice cream, and fold gently into the yogurt base. Spoon the mousse into a piping bag (no need for a piping tip) and fill half-sphere molds (3.4 and 5 cm in diameter), smoothing the surface well. Put in the fridge to cool and then freeze overnight.
Assemble the tart. Remove the base with chocolate ganache from the freezer, place in a serving tray and remove the acetate. Arrange the mousse spheres of different diameters over the ganache. Decorate with mini-meringues plain and painted with gold spray. Put in the fridge for about 6 hours to allow the ganache to soften and the mousse to thaw.

Comments: I truly enjoy making desserts that involve multiple components particularly because they can be made in advance and wait in the freezer or fridge. Finishing the dessert then is easy and fun (assuming it all worked well in the previous steps). For this preparation, Arianna’s video was very helpful, as the Sable Biscuit is quite a bit softer than I anticipated. Watching how she handled it was key to succeed. Also make sure you make the dough the day before you intend to bake it, it needs those 8 hours in the fridge. Another important point is the white chocolate ganache: you need it to be firm enough to slice and hold its shape. Arianna uses a specific brand of chocolate that would be a bit of a hassle for me to find. Using her proportions with the Lindt bar, the ganache ended up way too loose, so I made another batch using a 4:1 ratio chocolate to cream. You can probably get by with a 3.5:1, but not much less than that.
My schedule went like this: I made the biscuit dough on a Friday evening, baked it Saturday morning and made the mini-meringues, the chocolate ganache and the mousse on Saturday afternoon. Once the ganache cooled enough I spread it over the biscuit base and froze it. Sunday afternoon I un-molded the frozen mousse spheres, sprayed some of the meringues with edible gold color, and assembled the tart.
The only issue I had was the golden stars used for decoration. The ones in contact with the ganache held their shape well, but the yogurt mousse (probably due to its acidity) melted the stars within an hour or so.
The flavors were quite amazing, as the sweetness of the white chocolate ganache stood well to the bright flavor of the yogurt mousse. The biscuit base had excellent texture, even if I overbaked it slightly. It was hard to see it inside the ring, next time I’ll be more careful.
Arianna has a cookbook published online and I could not resist getting my copy. It is absolutely amazing, you can get it with a click here. The name is just too clever: Aria di Dolci. Loved it! Keep in mind it is in Italian, so you need to have some level of understanding of the language.
