I'm confused too. You bought a mixer - albeit a powerful and versatile one. The basic attachments that come with any KA are the paddle, the wire whip and the dough hook.
The paddle is the most versatile. You use it to mix or mash ingredients. Mashed potatos were an example - another would be any cooked hard squash or any root vegetable.
Shepards pie uses mashed potato as a topping.
The paddle would be good for
spreads that use a soft cheese as the base (cream cheese, ricotta, etc). You could also use it for
quick breads, which are fun and easy to make. You can use it to make pastry and there are lots of savory dishes like
pot pies, quiches, etc. that use pastry. Another suggestion are
quenelles or gnocchi.
The wire whip is for mayonnaise, whipping egg whites, whipped cream, etc. Whipped egg whites are used in various savory dishes -
souffles come to mind.
Lastly, the dough hook - for any dough that needs kneading - yeast rising bread, pasta, pizza dough, wonton dough, etc.
Hope this gives you some ideas.
PS
If you decide to junk that KA, PM me! I'll take it :!:
