A plain wooden pastry brush with food-grade bristles. No branding, nothing printed on it — the kind of tool that gets used until it wears out and is simply replaced.
It costs almost nothing and it does the job: egg wash on pastry, oil on a grill pan, butter over a hot loaf.
Sourced by Alfar Tierra Cocida in Spain to sit alongside their pottery.
Egg wash before the oven, oil on vegetables before roasting, melted butter over warm bread.
