Ingredients:
- 1 Large Egg (free-range preferred)
- 1 Tbsp Milk (whole or semi-skimmed) OR Water
- A tiny pinch Salt (optional)
Instructions:
- 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.
- 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.
- Add Liquid: Stir in the specified liquid (1 Tbsp milk or water) until fully incorporated.
- 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.
- Prepare the Surface: Ensure your item (pastry, dough, pie crust) is cold and ready for baking.
- 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!
- 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.
- 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.
- Bake Immediately: Bake according to your recipe’s instructions.
