How to grill halibut<br>Go to your local supermarket or fish market and purchase halibut steaks. [substeps] Look for steaks that appear solid without a fishy smell, and keep in mind that thicker steaks take longer to grill. Choose your seasonings or marinades.
If the steak smells fishy you shouldn't buy it. 
You should not buy the fishy steaks because they will go bad soon. I think the system didn't get that.
