Hi Simon,

Thanks for the reply. Looking at the photo of the Coco-Strainer it looks like the one I am using (cone shaped). Maybe then the issue is with my muddling of the Strawberries e.g. over muddled as I also ended up with a blocked spring on the Hawthorne due the "mush"!. I need reduce the amount of strawberries and muddle perhaps?

Also, as we were on a night of rum based cocktail experimentation still in awe of the classic Daiquiri (used your recipe measures > Daiquiri Natural #1). Just 3 ingredients, simple...sublime!
