How to Use a KitchenAid Mixer to Prepare Tomatoes for Canning Using the Fruit and Vegetable Strainer Attachment

If you’re tired of spending your summer days blanching tomatoes to prepare them for canning, let me let you in on a trick that has saved me HOURS in the kitchen. No more boiling water. No more watching the tomatoes for three minutes and then plunging them into ice water. No more peeling, chopping, and hoping the tomato juice doesn’t run onto the floor.

If you have a Kitchen Aid Mixer, the Fruit and Vegetable Strainer Attachment will change your life. Maybe I’m being overdramatic. Try it and you can decide.

Prepare Tomatoes

Once you attach the strainer to the mixer, prepare your tomatoes by washing, removing the stem, and quartering the tomato (depending on the size) into pieces that fit into the hopper. Then, run the tomatoes through the strainer attachment until they turn into a thick juice.

I demonstrate the process below:

Prepare for Canning

From here, boil down the juice to the desired consistency depending on what you’re making. Tomato sauce takes a few hours, while tomato paste can take all day. This also depends on how juicy your tomatoes were to begin with. Paste tomatoes like Roma are naturally thicker and will boil down faster than slicing tomatoes.

As a general rule, you’ll need to reduce by 1/2 to get tomato sauce and reduce by 3/4 to get tomato paste. For example, 4 quarts of tomato product after running it through this Kitchen Aid attachment will yield 4 pints of tomato sauce or 4 half-pints of tomato paste.

*Note – be sure and purchase the KitchenAid FVSFGA Fruit & Vegetable Strainer Set with Food Grinder Attachment. There is a strainer attachment, but without the food grinder, it will not work. According to the product details, this attachment will work with all models of Kitchen Aid stand mixers.
