A dough docker and a pastry cutter are both tools used in baking, but they serve different purposes and have distinct designs.
A dough docker is a tool used to prevent dough from rising excessively during baking. It typically consists of a handle attached to a roller with spikes or pins. When rolled over dough, the docker creates small holes or perforations, allowing steam to escape and preventing air pockets from forming. This results in a more even and flat bake, which is particularly useful for items like pizza crusts, flatbreads, and crackers.
On the other hand, a pastry cutter, also known as a pastry blender, is used to cut and mix fat (like butter or shortening) into flour to create a crumbly texture, essential for pastries like pie crusts and biscuits. It usually features a handle with several curved, parallel blades or wires. By pressing and rocking the cutter through the ingredients, the fat is evenly distributed, ensuring a flaky and tender pastry.
In summary, a dough docker is used to perforate dough to control rising, while a pastry cutter is used to blend fat into flour for a crumbly texture.
