I go through phases where I have to "perfect" a particular thing. Reefing really has cut into my baking time though.
French bread, baguettes, focaccia from starter. I was doing the no-kneading method with slow overnight rises on high hydration batter/dough. I was psycho to the point of taking the sponge to work so that I could babysit it and have it ready in time for me to bake when I took it home in the evening.
Genoise. I used it for a base to make European style rum cakes with rum syrup and pastry cream etc. When I was a kid, my family would get Italian rum cakes from Dianda's for b-day celebrations. Dianda's in SF makes awesome cakes and pastries. So, I had to figure out how to make rum cake.
Apple pie. Mainly as a way to practice making pastry dough. There was a bakery in SF Chinatown that made apple pie with the most awesome pie crust. Super flakey, but not hard. So that was another one that I had to figure out. With pastry dough, it's mostly technique, but also lard makes a big difference.
Apple frangipane tart. Mainly because I'm too lazy to make a properly crimped pie crust
Almond macaroons and chocolate version which is like a lumpy chocolate chocolate chunk cookie. I made those for a friend that had described to me her ultimate cookie fantasies.
We had a baking contest at work a month or so ago. There were categories for cakes, pies, and cookies. I entered all 3 with Daiquiri(strawberries & rum)cake, Chocolate dipped almond macaroons, and Apple Frangipane tart. They thought I was crazy for doing 3 entries, haha. There weren't enough pie entries, so that category got lumped in with the cakes. I ended up winning a 1st and a 2nd, hehe.
