In the bowl of a food processor, combine flour, salt and sugar. Add butter, and process until the mixture resembles a coarse meal (about 8-10 seconds). Homesteading Hack: If mixing by hand, use a pastry cutter to cut the butter in until the dough resembles a coarse meal.
With the machine running, add ice water in a slow, steady stream through the feed tube.
Pulse until the dough holds together without being wet or sticky; be careful not to process more than 30 seconds. To test, squeeze a small amount together. If it is crumbly, add more ice water, one tablespoon at a time. If it holds together, it’s just right.
Divide the dough into two equal balls, flatten into disks and wrap in plastic wrap. Transfer to the refrigerator and chill for at least one hour before rolling out.
