Viron, Chiboust aux Marrons

I'll lead with the cake: I ran to Viron (as always, the Marunouchi one) and got the Chiboust aux Marrons for 810 yen (really, but it's big), which is a chiboust top and a bottom that is sort of like a tart with chestnut halves in it. I'm slow to come around to chestnuts, but I'm getting there. Just the base as a chestnut tart is excellent, and I would like to see more chibousts and I've never had a better chestnut chiboust, so I'm saying this is great, which is 6th of 10 tried that I've found great there.

The running was too fast. Even noticing that my first kilometer was over 9 km/h, I couldn't get the average below 8.5 km/h going out, although I did coming back (still not going far enough or fast enough for fatigue to be a big factor). I'm seriously chewing through my 7-day running budget, which is why I've only run 31 km compared to my peak walking only a couple months ago of over 70 km (although I also have 20 km cycling this week, which counts only 1/4 of running). Of course, shorter and faster is more efficient and the best cake targets are somewhat close, although I'm going to have to just do the Gaien Walk again (even if I do 9 km/h again, I'll still be within budget) and get cake from Isetan (it's about time I had Jean-Paul Hévin cake again anyway, though I need to get to the Marunouchi location, too).

In home baking news, I started a new cake, which uses a pistachio macaron shell as a base. It's just a simple substitution of pistachio powder for almond power (simple if you can get the powder), but so delicious. Actually, it seems to "macaronage" a lot quicker, so I have to be careful not to over-mix. I had a fancy recipe with egg yolk and syrup which I failed with, at the stage of combining those two, so I went with a simple American pistachio buttercream, which might be too sweet. I'll try to wing a pistachio marzipan buttercream next time (I've still got lots of pistachio powder and enough pistachio paste for another batch), although probably not soon, as I've got a few dozen macarons in the freezer now, not all that successful, though: lots of chocolate ones with cracked shells and ones with chocolate-strawberry ganache, which isn't well balanced. You'll notice that I don't die the shells, or cover them when baking to keep them from getting brown.
