Ingredients:

  • 1 Large Egg (free-range preferred)
  • 1 Tbsp Milk (whole or semi-skimmed) OR Water
  • A tiny pinch Salt (optional)

Instructions:

  1. Prep the Egg: Crack the large egg (or separate if using only yolk or white) into the small bowl. Add the pinch of salt, if using.
  2. Whisk Aggressively: Use a fork or small whisk to beat the egg until the yolk and white are completely uniform and slightly frothy. You must ensure no thick, gelatinous strands of egg white remain.
  3. Add Liquid: Stir in the specified liquid (1 Tbsp milk or water) until fully incorporated.
  4. Strain (The Professional Secret): Pour the entire mixture through a fine-mesh sieve set over a clean bowl or ramekin. Discard any chalazae or pieces of shell that remain in the sieve. This step guarantees a smooth, streak-free coat.
  5. Prepare the Surface: Ensure your item (pastry, dough, pie crust) is cold and ready for baking.
  6. Load the Brush: Dip the pastry brush lightly into the strained wash. Wipe off the excess on the rim of the bowl. The brush should be damp, not dripping—less is more!
  7. Apply Evenly: Brush the wash onto the surface of the dough using smooth, even strokes. Do not allow the wash to pool in the folds of the pastry or along the edges.
  8. Second Coat (Optional): For a deeper, more pronounced colour, chill the brushed item in the refrigerator for 5–10 minutes, and then apply a very thin second coat.
  9. Bake Immediately: Bake according to your recipe’s instructions.
