I bought: frozen peas, peaches, and mangos, plus fresh pears, bananas, and sweet potatoes. WF was out of organic avocados; I'll have to pick up those later this week.

I started by steaming the frozen peas, then dumped them in the food processor. I later learned that the blender does a much better job of making a superfine puree.
The mangoes and peaches needed time to thaw, so I peeled and pureed these beautiful D'Anjou pears.

The thawed peaches were easy to puree and pour into leftover baby food jars my friend Julie shared.
The mango puree went into a regular ice cube tray.
Ryan enjoyed mango and sweet potato for breakfast.
I calculated that, based on the cost of 2.5 and 4 oz jars of Earth's Best organic baby food, I made over $50 worth of baby food for an investment of $29 in food and $5 for ice cube trays - not a bad return on investment for 3 hours of work! It remains to be seen how long all this food will last, what with Ryan's hollow leg and all...
