1. Prepare Your Loaf: Ensure your sourdough loaf is well-proofed and chilled (if you proofed it in the refrigerator). A cold dough is firmer and easier to score cleanly. Lightly dust the top of your loaf with rice flour or all-purpose flour using a small sieve or your fingers. This helps the scores stand out and prevents the lame from sticking.

2. Hold Your Lame Correctly: For most cuts, hold your lame or razor blade at a shallow angle, about 30 to 45 degrees, almost parallel to the surface of the dough. This angle creates a “flap” or “ear” that will open beautifully during baking. For deeper, more structural cuts, you might hold the blade more perpendicularly (90 degrees).

3. The Simple Cross or Plus Sign: For a classic look, make one long, confident cut down the center of the loaf. Then, make another cut perpendicular to the first, crossing it in the middle. These cuts should be about 1/2 to 3/4 inch deep. This pattern allows for excellent oven spring and a rustic appearance.

4. The Basic Square or Grid: Make two parallel cuts running lengthwise down the loaf, spaced about 1-2 inches apart. Then, make two or three parallel cuts perpendicular to the first set, creating a grid pattern. These cuts should also be about 1/2 inch deep. This is a simple way to get a lot of surface area for expansion.

5. The Wheat Stalk (Ears of Wheat): Make one long, shallow cut (about 1/4 inch deep) down the center of the loaf. Then, make a series of short, diagonal cuts branching off from the main line, alternating sides, to resemble wheat stalks. These smaller cuts should be very shallow, mostly for decoration.

6. The Leaf Pattern: Make a single, slightly curved cut down the center of the loaf. Then, make several short, curved cuts branching off from the main line, angling them outwards to mimic the veins of a leaf. Keep these decorative cuts shallow.

7. The Swirl or Spiral: Start at the center of your loaf and make a continuous, shallow cut (about 1/4 inch deep) in a spiral pattern, working your way outwards to the edge. This creates a beautiful, dynamic design.

8. Be Confident and Quick: Make your scores with a swift, decisive motion. Hesitation can cause the blade to drag and tear the dough. Don’t be afraid to apply a little pressure for the deeper, structural cuts.
