Silke, if you want small Financiers, they have the mini-financier mold at Sur La Table. I don’t think they have it in the store but you can get it online. This is the one I bought from them a few months ago:
I bought two of the 24 portions. It’s a french brand and a bit pricey but I’ve used it several times and it works pretty well. I have not had a problem with sticking and the financiers come out pretty easily. I just pipe the batter using a pastry bag.
I’ve used them to make multiple batches. It’s easy to pop everything out after they cook and wash the mold for your next batch. You don’t even have to grease it every time you use. I’ve only greased the first time (per instructions).
I have a different almond financier recipe that I have used but I’d like to try Rose’s recipe from the new book.
