How many crayfish to cook

Crayfish are boiled to size 15-20 minutes, salting the water well and alternately running the crayfish into boiling water upside down. Cook small crayfish (60-70 grams) for 15 minutes, medium (70-90) - 17 minutes, large (100-110 grams) - 20 minutes. To test the doneness, look for the color - ready-to-eat crayfish are bright red.
