There I was, on a fishing vessel on the Bering Sea...
now if you watch TV, especially the discovery channel, you might be thinking: Oh wow! How exciting! And it can be... under the right circumstances. But on a trawler in bad weather with long ol' steams between the fishing grounds and land it can get pretty slow... slow enough that one starts to search for all forms of entertainment. I'd boarded this vessel with one piece of intel from a prior fish biologist: they have an amazing cookbook. It's all white. If you find it, get me the name of it.
Well JD, if you're out there, it's America's Test Kitchen's epic book of recipes. That's not the exact title but a google search will get you there.
It made for some great reading. It had all sorts of science and pictures and insight; all sorts of things to geek out on, essentially. So here's my adaptation of their lemon tart to get things going.

Disclaimer: This tart is a pretty involved process. The crust has to be formed, cooled, rolled out and put in the tart pan, frozen and then baked. To add to the process the crust has to be warm when the lemon curd is poured into it or it wont cook properly. Timing is pretty important. It's a great project to take on when you're around the house doing laundry or killing time while unemployed. It's not such a great project when you have places to go or are especially distracted.
Alright, with that out of the way, it's fun. And your first bite will validate the whole process.
Zest and juice the lemons before putting the filling together... it's just easier that way.
New toys in the kitchen so everything (I remember to weigh) is going to have a mass equivalent.
Crust1 cup rice flour (generous) or 135g
1/4 cup cornstarch 35g
1/4 cup tapioca flour 30g
2/3 cup confectioners sugar 100g
1/4 tsp salt 3g
8 Tbsp cold unsalted butter cut into chunks
1 egg yolk
1 Tbsp heavy cream
1/2 tsp vanilla extract
Whisk the dry stuff together and cut in the butter with a pastry cutter. If you don't have a pastry cutter get one. They're cheap and they make a mean pastry. A food processor, especially one with the bowl and blade chilled in the freezer first, would also make a good pastry but half the fun of baking is getting your hands in it. Most electrical appliances are overkill and extra dishes.
Pastry recipes generally call for cutting the butter in until you get to a consistency of something between coarse cornmeal and pea-sized chunks. I could get into a whole deal about gluten being like building blocks that form long chains and get gluey during preparation, but I'll do that somewhere else. The flours in this recipe are lighter and prone to forming wet dough in quantities equal to wheat flour, so the consistency you're shooting for in this case is like lumpy flour.
Beat the egg yolk, cream, and vanilla together, add to the mix, and combine with a fork, big wooden spoon, your hands, what ever works best, until you have a uniformly soft and workable dough. If using your hands be quick so you don't melt all the butter and wind up with wet and sloppy mush. Form the dough into a six inch disk, wrap in wax paper and chill in the refrigerator for at least an hour.
Once the dough is chilled roll it out on a floured surface (I like using a 50:50 mix of rice flour and confectioners sugar for this part) and work it into a 9 to 9 1/2 inch tart pan. Stick it in the freezer for 45 minutes. This is a good time to get started on zesting and juicing lemons unless you're a pro and can do this at lightning speed. Cutting yourself on the grater is a bad idea. Lemon juice sucks in cuts.
Heat the oven to 375 degrees. When the crust is fishished in the freezer fit a piece of aluminum foil or parchment paper over it and cover in a layer of pie weights (beans, rice, ceramic balls designed for this purpose, and bake for 30 minutes. Start on the filling.
Rotate once half way through. Remove the foil/parchment and bake for another 5-8 minutes until it's golden brown. Turn the oven down to 350 when the crust comes out at the end.
My crust sort of sank the first time I made this recipe because I was a bit light on the flour. I used a spoon to push it back up the sides; it's really soft before it goes back in the oven for that last 5-8 minutes.
Filling
7 large egg yolks, plus 2 large eggs
1 cup + 2 Tbsp granulated sugar
2/3 cup juice and 1/4 cup finely grated zest from 4 or 5 medium lemons
4 Tbsp unsalted butter cut in chunks
3 Tbsp heavy cream
Whisk the yolks and whole eggs together in a non-reactive (e.g. glass) bowl. Whisk in sugar until combined, add juice and zest and whisk some more then transfer to a non-reactive sauce pan. Add butter. Use a wooden spoon to stir constantly while heating to 170F over med-low heat. This takes a while but when the change in consistency happens, it happens quickly. It will curdle if you ignore it. Push through a strainer into a clean non-reactive bowl, stir in the cream and then pour it into the warm crust. Throw the works back in the oven (now turned down to 350F) for 10 to 15 minutes, until it's shiny and the center 3 inches are jiggly. Cool for 45 minutes then remove from tart pan.
That's it folks. Enjoy!
