Recipe: Yuzu Tarts

I Was intending to rest this weekend, having travelled in spats for most of the month but Colin easily convinced us that a trip to TOTT was long overdue. The place is a wonderland of kitchen appliances, steamers, knives, pots and all manner of culinary goodness, including some gourmet ingredients for tarts and savouries. I was immediately reminded of the Japanese yuzus that I had from a recent trip, still sitting in my fridge. Between yuzu tarts and taking a break, what's a girl to do?

I filled half of the sweet tart dough with chocolate ganache and then the other half with yuzu cream, made from the Pierre Herme lemon cream recipe, also found here on this blog. In place of lemon juice and rind, I used yuzu rind and juice and topped up with a bit of orange juice.

1/2 cup sugar
Finely grated zest of 2 yuzus
2 large eggs
1/4 cup fresh yuzu juice, topped up with orange juice
180 grams unsalted butter, cut into small pieces

Put the sugar and zest in a metal bowl set over the pan of simmering water. Rub the sugar and zest together until the sugar is moist, grainy and very aromatic. Whisk in the eggs, followed by the yuzu juice. Keep whisking to stop the eggs from scrambling. The bubbles will get bigger, and then, as it gets closer to 180 degrees F, it will start to thicken and the whisk will leave tracks. As soon as it reaches 180 degrees F, remove the cream from the heat and let it cool. Strain it into the container of the blender and discard the zest.

Turn the blender to high (or turn on the processor) and, with the machine going, add the butter about 5 pieces at a time. Scrape down the sides of the container as needed as you incorporate the butter. Once the butter is in, keep the machine going—to get the perfect dreamy, airy texture, you must continue to blend the cream for another 3 minutes. I kept the machine going till the cream thickened up into a spreadable consistency but you can also leave it to harden in the fridge.

Later, when they had set, I topped each yuzu tart with a raspberry and the chocolate tarts with melted, smooth ganache and then flecks of goldleaf. There's something about tarts that makes me so happy on a sunny Saturday! These little cases are a real treat too, I'm thinking of filling them with darjeeling cream (like mini darjeeling tea tarts) for future tea parties.
