Run, don’t walk, to Adriano Zumbo Patissier.
Why? Well, for a limited time, some old favourites are making an appearance for Valentine’s Day. They include:
Dulce de leche éclair
Here is a quick montage in case you missed them the first time. Charming Charles (from the shop) advises that they are available until February 15. And the dates are when they first appeared (approx.)
PS: The Houdini is not actually available at present; but it could be if one can be naggy enough. So, if you visit the shop, please put in a good word for it on my behalf.
