Recipe Tips
- Can I use canned crab meat?
Yes, just be sure to drain it well and gently fold it in during the final step. - How to substitute frozen vegetables:
Use slightly less if subbing frozen green beans, corn, or lima beans to avoid watering down the soup. - Best potatoes for soup:
Gold or Yukon potatoes hold their shape well and add a creamy texture. - What does Worcestershire sauce add?
It enhances the umami flavor and adds depth to the broth. - How to avoid mushy crab meat:
Add it at the very end and avoid over-stirring or long cook times after adding.
