I used the wholesomebabyfood website as well. I didn't know what foods you were supposed to peel, to cook, etc. I used my small cuisinart food chopper. Depending on how thick/chunky I wanted it, I'd hold down the button or just 'pulse' it. Or I'd mash some with a fork and then add that to the pureed stuff, so it was a mix of the two. I mostly used my cuisinart for fruit (pear, apple, strawberry blend). I'd toss in some pineapple sometimes for differnt flavor. I'd also do green beans or peas. But mostly, I wanted more protein for my son. I tossed black beans in my cuisinart, along with some cooked chicken breast and rice. It was thick, so I'd add some olive oil. He loved it. Oh also, zuchinni and squash were great to use in the processor. You could 'pulse' it, then dice some up really really tiny and add that to the pureed stuff. It was runny, so I would add rice cereal to thicken it up.
But when in season, I bought fresh pumpkins (all sorts of colors and shapes) and baked them. They didn't really need much mashing.
Bananas are very easy to either smash or puree and make it the consistency you want.
Anything I made, I'd store it in snack sized bags and toss them in the freezer, keeping some out of course, for that week. Then when I needed something for lunch or dinner for my son, I'd take a bag out of the freezer, pop it into the fridge the night before. I highly recommend this. It makes life easier to cook just one day for your baby, then pull out what you need as you need it.
