When it comes to making mashed potatoes, tomato sauces, creamy soups, applesauce, baby food, etc, a good rotary food mill is an essential tool for the job. It makes quick work of processing fruits and veggies into silky smooth purées, removing skin, pulp, and seeds in the process. It's actually better than a food processor in a lot of cases.

As noted by Serious Eats:

There's so much you can do with a food mill: It'll plow through tomatoes (even the skins!) for a super-smooth tomato sauce and make quick work of mashed potatoes for a crowd without requiring too much effort. But most food mills designed for home cooks just aren't up to the task—they're frequently either too small or not strong enough.

If you want to invest in a good food mill, get one that's professional-grade, like this JB Prince food mill. It has three different disk-shaped graters that can chew through all sorts of fruits and vegetables with no trouble at all.

We have to agree. Get this mill for $167 on Amazon and marvel at how many uses you find for it.
