Creamed Swiss Chard Tart
Combine the water, salt, butter, cake flour, and high gluten flour in mixing bowl; mix until elastic. Let rest in cooler and make a butter block by beating the butter, lemon zest, and flour together until smooth.
Roll the dough into a square. Place the butter in middle, and fold over the corners. Roll the dough until ¾-inch thick, and do one single fold. Repeat this process 6 times, placing in the refrigerator between turns.
For the Swiss Chard Filling:
In a large sauté pan, sautée the shallots in oil until translucent; add the swiss chard and cook until wilted. Add the salt, pepper, nutmeg, sugar, and cream and cook until the flavors combine.
