How to judge the quality of wood furniture
Look for solid wood.
If a store claims that a piece of furniture is solid wood, that means that it only contains wood. Plywood, on the other hand, is layers of wood and resin or glue.

OUT: Solid wood tends to be more durable, though it is usually more expensive. If you can see an unfinished edge of the furniture, you should be able to tell if it's plywood or solid wood.

How to debone a trout
Remove the head of the trout.
Filleting should be done when you wish to serve only the finest cut of the fish, rather than cooking it whole. Start by cutting through the neck of the trout at the groove of the gills.

OUT:
Angle the blade of your knife so that you're cutting toward the head rather than the body to preserve the meat. Always use a filleting knife or other sharp blade when preparing fish.
