He most recognised design, this strainer features holes in the head and a spring around the outside. A Hawthorn cocktail strainer will often feature “ears” on the sides to help keep the strainer in place on top of a shaker tin.
The head of a Hawthorn strainer is smaller than an average shaker tin, with the spring designed to fit snugly inside the opening. If a Hawthorn strainer has ears, these will keep the strainer in place.
