Observations on Dressing Fish

Ingredients

Directions

If the fish is not cleaned, clean it thoroughly.
For boiling, add salt and vinegar to the water for firmness.
Salt the fish and let it sit for a day if not very hot.
Soak fresh-water fish in strong saltwater to remove muddy smell.
Put the fish in cold water and heat gently to avoid breaking.
For crimp fish, start in boiling water, then add cold water to reduce heat.
Check if the fish is ready by seeing if it leaves the bone.
Remove the fish immediately from the water to prevent it from becoming woolly.
Keep the fish warm by placing the plate over the kettle and covering it with a clean cloth.
