Put dry ingredients in a bowl and sift through. Add liquid and knead for 5-10 minutes. Let dough rest in bowl covered for at least 10 minutes. You can wait a few hours even if you get distracted. Knead again for 5 minutes. At this point you can leave your dough until later or you can shape or roll it out and fill it and let rise for 30 minutes to an hour before baking.
Freeze-dried food is nothing new. As early as the 13th century, the ancient Quechua and Aymara people of Bolivia and Peru pioneered a form of the process by exposing potatoes to the freezing temperatures of the Andes overnight, then drying them in the sun. In 1937, Nestlé used industrial technology to create the world’s first freeze-dried coffee, and in the 60s and 70s, the US military shipped freeze-dried food rations to the troops in Vietnam.
