I haven't read the other responses, so sorry for any repeated info. First, I highly recommend the Super Baby Food book! As for storing...
I bought cheap ice cube trays (I think $1 each) and froze the pureed fruits or veggies with a piece of foil on top. Then I would pop out the cubes (which are about 1 oz.) and store them in marked/dated freezer bags. When I wanted to use one, I would microwave it for about 5 seconds and stir it well to make sure there was no icy chunks or hot spots. These cubes are also great for summer time - stick them in a Fresh Food Feeder (http://www.munchkin.com/products/detail.html?section=devS...) and let them suck away on hot days (you might have to shave the cube down or cut it in half to make it fit).
When she was old enough for yogurt, I would buy 6 oz. containers of plain, organic, whole-milk, yogurt and mix in the fruit she had already had. It was cheap and a great way to introduce yogurt. After that we moved on to YoBaby and she still gets that for breakfast most mornings almost 2 years later (she still needs the extra fats from whole milk products because she's small).
When she got a bit older, I would make things like whole grain alphabet soup or high-fiber, high-protein pasta loaded with pureed veggies and white beans. I froze them directly in small glad or zip-lock containers and would thaw the portions overnight in the fridge before using. The 4oz. size is great for this and they stack perfectly!!
Another quick tip, is using pre-pureed foods in adult sized cans or just puree canned goods. This saved me a lot of time, because I would just open them up, puree in the blender (if needed) and fill up the trays. I would hit PCC and stock up every few weeks. :-)
More info about freezing in plastic has come out (same issues as heating foods/beverages in plastic), but honestly, I don't know how to avoid freezing in it. You can store the food in glass containers, but what do you freeze the cubes in? I haven't seen metal ice cube trays since I was little, and those probably had lead. LOL! I just make sure I never heat foods in plastic because at least I can control that.
It's been awhile since I was making baby food regularly, so I probably left out some ideas. I will admit, I never made my own rice cereal (Earth's Best makes great cereals, so I didn't find the need - or have the time). Also, I did buy organic jarred food when our daughter got older and I was only using 1 jar a day to add extra fruits or veggies to her diet. I just didn't have the time while making regular meals for her too. But for over a year, I did mostly make her foods and it was easy and great! Have fun and enjoy this time. I remember thinking I couldn't wait until our little girl was a bit older because it took so long to feed her, but now I miss that one-on-one time. Also, she's not a great eater (never has been) and meal-time takes longer than ever now because she's a super-independent 2 year old going on 14. ;-)
