Strainer
You will need at least one strainer that fits inside your shaking tin. There are rounded strainers that will you hold in the tin and there are strainers that have a spring and to catch the ice. A good strainer is essential for making Martinis, Sidecars, Manhattans, and more. If you want to be extra thorough, you can get an additional mesh strainer to catch any citrus pulp or tiny pieces of ice. One strainer will be good enough for most home bars. If you find some ice getting through your Martini then you can grab an additional strainer.
