see my comments on chicken posted on 9/5/03: "how many chickens does it take"
Typically they refer to precooked weights, however, I find that as long as you keep the chicken moist- 1oz cooked is 1-p block. I wouldn't worry too much about it if you do not like the details. You can always check by reading the nutritional lable- which is for pre-cooked. What might be easiest is to figure it out ONCE based on the pre-cooked weight, then compare the weight to the after-cooked weight. From then on you can just use the after cooked weight to estimate the p-blocks. What I found for chicken is that pre-cooked lables say 4oz is 3-p blocks (21 grams)- but by the time I cook it (as long as it is moist), the 4oz shrinks to 3 oz- making it 1oz = 1 p-block after cooking.
Hope I did not confuse you- sorry if I did.
