salted butter crackers

salted butter crackers
via myself and the little red kitchen 

1 3/4 c. all-purpose flour
     or gluten-free:
     127 g. (4.5 oz) tapioca starch
     42 g. (1.5 oz) sweet rice flour
     42 g. (1.5 oz) sorghum flour
3/4 – 1 tsp. sel gris or kosher salt or sea salt
9 tbsp. (127 g./4.5 oz) cold butter, cut into 18 pieces
3 – 5 tbsp. cold water
1 egg yolk, for the glaze

Pour the flour(s) and salt in a food processor and pulse to mix. Drop the butter in and pulse until it looks like coarse meal with pea-sized and smaller pieces. While the machine is running, slowly add some of the cold water. Only add enough water to make a dough that almost forms a bowl. It will be very malleable.

Move the dough onto a big clean cutting board and form it into a square. Wrap it in plastic and refrigerate for about 1 hour (or up to 3 days).

When it's time to bake, preheat the oven to 350 degrees Fahrenheit and make sure your rack is centred. Line your baking sheet with a silicone baking mat or parchment paper.

Roll the dough out between sheets of plastic wrap until it becomes a rough rectangle that's about 1/4-inch thick and about 5 by 11 inches. Peel it onto your prepared baking sheet.

Whisk the egg yolk with a few drops of cold water, and use a pastry brush to brush the dough with the egg glaze.

Bake 30 – 40 minutes, or until golden. It should be firm to touch, but with a little spring when you press its centre. Dorie says the perfect break-up is crisp on the outside and still tender on the inside. When it's not too fragile, transfer it to a rack and let it cool to room temperature. Break into cracker pieces  – or let your guests break it up – and serve with cheese.
