NB: If you use glass, make sure it is not hot when you start shaking. A rapid change of temperature could cause even the toughest of glass to break!
Mason Jar / Kilner Jar / Flip-top jar
Good and solid, watertight and with a flip-top lid that can double as a built-in strainer.
Needs to be big enough for the ice and liquid to be able to move from end to end as you shake it. A screw-top lid does make an excellent watertight fit; you’re much less likely to wear your cocktail! The lid can also be used as a strainer.
Tupperware Cup with Lid
Solid Tupperware containers with a clip down lid may look a little odd, ugly too, but they work even better if you shake the ingredients sideways.
