i was told to use the oz on the box for the pasta. Also there is a web site that shows it comes out just right. I can't recall her but she's here.

so you weigh the dry pasta in a bowl or lose if it's spaghetti. That's what we do in WW.
Cereal: We can use a measuring cup, but if you really want more acuuracy, go for the in the bowl way. Tear the bowl, then add your cereal.
Liquids, I use a measuring cup.
meat: I use my scale, just slap it on there, lol but that's just me.
Ice cream. I would use the bowl on scale. too much wiggle room there.
