If you boil 1 pound of live Crawfish how much will they weigh when they are finished cooking?

Will the gain weight due to absorbing water?

Remain the same weight?

Lose weight from loosing body fluids?

What says the FDB?

I think lose weight. Probably down to 0.8 pounds or so.

lose about 10% but is varies, biggest thing is how fast you weigh them after they come out of the pot

And why is this a question?

America's Test Kitchen should research this. There are two factors that I can think of that would affect the weight.

The first being that food generally loses weight when cooking. Don't know if this applies to boiling.

The second would be the amount of liquid the crawfish absorbs which could vary depending on the soak time and the amount of empty space within the crawfish that could hold liquid.

The results would probably be too inconsistent to be conclusive but I'd be interested to see.

Gotcha.

Just curious if you measure the weight of the whole batch after they're done.

I know the weight that I boil in a night then compare it to what I sold plus what's leftover

I was passing past the back porch at Sammy's the other night and saw a Stainless coiled chiller looking thing in one of the pots.



What's that used for in Boiling Crawfish?

I would think that would be smart. Plus you could pre-heat water for another batch with the runoff from that.

What's the typical percentage of dead crawfish in a sack?

I was thinking about it for efficiency purposes

Soaking/cooling down a full pot of crawfish while simultaneously filling up another pot of water with HOT runoff water from the chiller so you already have near boiling water for the next batch...?

Depends on the time of the year, how they were taken care of,where they were caught(wild or farm raised), and how long they have been out of the water. Earlier in the year when they are weaker and thinner shelled you may have as much as 3-5lbs per sack dead after just a few days out of the water. Later in the season you can sometimes keep crawfish for 6-7 days and only have 1-2lbs dead.

I always figured you will lose about 15-20% with dead crawfish and shrinkage (raw versus cooked weight). So if you boil a raw 40lb sack you should get 32-35lbs cooked after dead and shrinkage.

this varies a lot

right now? I cooked 2 sacks last night that were in my cooler from Thursday and didn't have 5 dead crawfish

a foggy February morning? I'm not keeping them more than a couple days
