Hi DrLilac!
Glad to hear that Ava is doing so well with solids

I have made chicken puree with great success - just be careful when introducing it, it can cause an allergic reaction... I would use the 3 day wait rule before and after just to be vigilant.
I baked a couple of boneless, skinless chicken thighs until well done. Put them in the fridge overnight and then rough chop them and into the blender they go. Just pulse them and they will make a fine mince in a minute or so. I used steamed pears for moisture and to make the flavour a bit more mild... DH tasted it (I am a vegetarian) and he said it wasn't bad

Freezes awesome! Dark meat has higher iron levels and lots of good fat for baby

I found that white potatoes don't freeze well on their own, but may if mixed with another veg or a fruit - I haven't tried though. I have frozen pasta as part of a puree, but never on it's own. I mixed broccoli, zuccini and pasta and DD loved it!
Cheese freezes well too.
