Thaw the snow crab and rinse
Heat oven to 325 degrees and cook for 15 minutes
If serving cold, Let cool and place in refrigerator for at least 30 minutes
Mix together the ketchup and horseradish to make the sauce
If serving warm while the crab is in the oven in a saucepan
Saute the minced garlic just a minute over medium heat without it burning.
Add the 1/2 cup of butter and heat until melted.
If you let the butter just get slightly scorched, it actually adds a delicious flavor to the butter sauce.
