This is an odd recipe. It's called Brittle so it sounds like a candy, but it's a flatbread like a cracker or a not very sweet cookie. It reminds me of cardboard, but in a good way.
Brittle
1/4 cup butter
1/2 cup sugar
3 cups flour
1 egg
Milk to make a stiff dough
Combine the butter, sugar and flour. Stir in the egg and enough milk to make a stiff dough. Knead until smooth and satiny. Divide in half. Pat out each half on a floured board that has been sprinkled with salt. Grease two cookie sheets, and put the dough on them and roll out very thin. Bake 20 minutes at 325 degrees.

Here's another:
Seed Crackers
1 cup flour
1 tsp. kosher salt or sea salt
1 tsp. sugar
2 1/2 tbsp. butter
1/2 cup milk
1 large egg
1 tbsp milk
Mix of dill, sesame and/or poppy seed
Combine the flour, salt and sugar in a bowl. Cut in the butter, not too fine. Add the 1/2 cup of milk. Knead by hand for 5 minutes or use the dough hook on your mixer for 5 minutes. Cover with wax paper and let stand for an hour.
Take the dough ball out and divide it into 4 equal parts. Roll each piece out on a flat surface dusted with flour, keeping the other pieces in the bowl and covered until ready.
Roll out the dough as flat as you can and transfer to a cookie sheet covered with foil.
Using a pizza cutter, cut the dough into strips, then again to make squares.
In a small dish, beat 1 egg and the remaining 1 tbsp of milk. Using a pastry brush, lightly coat the dough with the egg mixture. Sprinkle with the poppy and sesame seeds and bake at 300 degrees for about 10 minutes.
