I made a crab dish the other night and I followed a recipe on Pinterest rather than my moms - it called for canned crab even though I've never used it, always fresh crab. Anyway, the recipe is a labor of love and DH hated it!! The canned crab tasted like cat food.

I'm not a great cook so in the 8 years we've been together, we choose restaurants over cooking at home, which is expensive and unhealthy. Fill me in, what are terrible ingredients to substitute?! What are your biggest cooking mistakes?
