I used freshly-frozen peas (10 ounces), a basket steamer, medium sized pot with lid, one inch of water, and food processor, spatula and left-over Gerber 1st Foods plastic containers (I am still waiting on my other containers to come in the mail).
I started by boiling an inch of water in the bottom of the pot and set the peas in the steamer basket on top, covered, and boiled for 5 minutes. When the 5 minutes was up, I reserved the cooking water, then I then rinsed the peas under cold water to stop the cooking. Next, I transferred the peas to the food processor and blended until smooth, adding the cooking water until I liked to consistency for Mason.
I used a tablespoon to scoop the peas into the Gerber containers and so I could keep track of how much I was transferring to the containers. I knew ahead of time that each Gerber container comes with about 3 tablespoons of food when you buy them. I filled 6 Gerber containers with 3 tablespoons each, totaling 18 tablespoons of food.
Total time spent from start to clean kitchen was 15 minutes.
Here is the best part:
Gerber 1st Foods 2 packs= approx. $1.00 so 6 total (3 2-packs) would be $3.00
Doing it my way, 6 containers (made from 10 ounces of peas) = $.70
That's a savings of $2.30! And no preservatives and/or added acid (seriously WTF?). The frozen puree lasts 3 months in the freezer or 3 days in the fridge. I don't know about you, but my time is money and 15 minutes is nothing compared to the benefits of making my own food. Plus, it is so damn pretty!
