Pastry brushes are important instruments in any commercial kitchen or bakery as they can handle several tasks that very few other utensils can manage such as covering pastries with an enticing butter glaze or coating glaze onto a ham. Update International has the perfect option in its 1 1/2" Boar Hair Flat Pastry Brush (WPBM-15). This brush features boar-hair bristles which are significantly more pliable than their synthetic counterparts. They tend to hold much more liquid and spread much more evenly than nylon brushes.
