They’re all tools in the kit, some work for a lot of applications some for fewer the physics behind how the thing works is kind of interesting, I did not get one from Santa so, I will get my selfish self one soon.
Think of it this way,
If Escoffier had been able to use a cuisinart he certainly would have, instead, he had a kitchen brigade that would be the next in line to whip egg whites and cream by hand. Tools make the project easier, sometimes. To be honest the best accessory is a set of the GOOD 304SS baskets. They are better. Baskets do most everything I need. I guess that’s why I have not gotten a Vortex yet. Just made up a batch of Parmesan wings, would love to try the Vortex with that but, baskets will get the project done just fine.
