Plural of dasher; people or things that dash or move quickly, or the paddle or beater inside a churn used for making butter and ice cream.
From 'dash' (to move quickly, or to strike) + -er (one who does the action). The 'dasher' for churning is a literal tool that dashes the cream or custard around inside the churn.
A 'dasher' in ice cream-making is the spinning blade that literally dashes the mixture, which is why old cookbooks and ice cream shops still use 'dasher' for the churning paddle—it's a brilliantly descriptive word for what the tool actually does.
