Being monkfish is a firm fish it will hold up on the grill very well. Over a medium-high heat on the grill cook for 5 to 6 minutes per side and let stand for about five minutes before serving. Unlike tuna where you cook it rare, you want the monkfish to be done. Look for an internal temperature of 145 degrees.
Insulating basement walls in cold climates is a great way to keep your home warmer and drier. However, special care should be used when insulating concrete (or block masonry) basement walls. Below grade concrete foundation walls are very col and damp. If you were to insulate the walls with regular fiberglass batt insulation it is very likely that a mold problem would develop.
The stud walls are built tightly against the foam pressing it to the foundation. Fill the stud cavities with un-faced fiberglass batts for a toasty warm basement. The foam insulation method works best if the foundation walls are smooth. If the basement is an old stone foundation, spray foam insulation companies can spray expanding foam directly on the rough masonry. It'll be expensive, but it can be done and it will do a fantastic job.
