A three piece cocktail shaker is super easy piece of kit to get the hang of using. Tip all your ingredients in the jug or base of your shaker, as per recipe instructions. Then add with a good measure of ice and close the cap firmly, with the strainer in place. Gripping the base in one hand, secure the cap with the other and shake vigorously for about 30 seconds. Then remove the cap and strain the liquid into your glass free of ice and other ingredients for a magical cocktail.
