As good as advertised. Could lighten up on salt. Cut into squares. Amazing!
All-purpose flour 2 1/4 cups (285g)
Salt
3/4 tsp (4-5 g)
Sugar
1 tsp (18 g)
Baking powder
4 tsp (19 g)
Butter, very cold
1/3 cup (75 g)
Milk, very cold 1 cup (225 g)
1. Preheat oven to 450°
2. Place flour, salt, sugar and baking powder in food processor and pulse for a few seconds to combine.
3. Cut butter into small pieces and add to food processor. Pulse half a dozen times and check for the size of the butter pieces. Repeat if necessary until the butter is in pieces roughly the size of peas.

4. Put flour mixture in a mixing bowl and add the cold milk. Toss together gently until barely combined.
5. As soon as the dough holds together, turn it out on a lightly floured counter. Gently "knead" the dough a few strokes until it is a mostly a cohesive ball.
6. Roll the dough into a rectangle 1/2-3/4 inch thick, depending on how tall you like your biscuits. Cut into 2 inch circles or squares, you should get ~6, and place on a parchment lined cookie sheet. (See note about leftover dough.)
8. Bake at 450° for 8-10 minutes. Butter and eat while still warm.
