this is not a spur-of-the-moment thing. you need to plan for it. it requires a half hour of furious kneading. (if your kid doesn't run in the kitchen all horror-stricken, you're not pounding hard enough). but once you got that part done, you can crack open a celebratory beer: prevailing wind is blowing. the recipe is here, and the only note is about the flour: the better the quality of it, the better your finished product will be. i typically use king arthur bread flour, even though some recipes call for plain flour.
i think the hazelnut frangipane recipe belongs to jacques pepin, but i'm not quite positive. i remember it was used in an apple tart, but where, i can't recall. you need one pound shelled hazelnuts, that's 454 gr. if you're lucky enough to find blanched ones, hooray for you, but if you don't it's really not a problem. toast the hazelnuts in a single layer, for 7-8 minutes at 375F. the skins will come off easily when you rub them with your fingers. it doesn't have to be perfect, you don't have to drive yourself crazy about it.
put the nuts in the food processor, with 3/4 cups sugar, 3 eggs, 3 tb butter and a ts vanilla. whizz until pulverized. i like a bit of texture, so i don't let it go to paste, i stop when it's still grainy. that's it. it's ready to be spread in the dough. i had a little bit left over, about 3/4 cup, but i promptly wrapped it up and put it in the freezer. it has aspirations of becoming the base lining in a sour cherry tart.
this is the fig filling. maybe it would have worked better had i used less, and i nearly wimped and did, but i had finished the celebratory beer by then, and i was feeling mucho macho.
the hazelnut one. very well balanced, the filling just a notch sweeter than the dough. this is exactly the kind of thing that pops into my mind when i hear the term 'home cooking'. it's comfort food, if not all desserts are comfort...
i love the crust. a lot of people sprinkle extra sugar or sesame seeds on top, but i like mine plain, with just the sheen given by the egg wash. what's more: cozonac makes a mean french toast or bread pudding when i have leftovers, which is rarely enough. not a bit goes to waste. i love food that permits a second shine.
