  1. You can swap shrimp for any kind of seafood you like and remember to cook this over medium heat ONLY. Also, DON’T forget the finishing mixture. It is the secret to make any Cajun boiling more delicious.
  2. If you don't have lemon pepper seasoning, you can substitute for 2 tbsp (1oz) of lemon juice & 2 tsp of ground black pepper.
  3. If you don't have brown sugar, you can substitute for 1.5tsp (0.2oz) of granulated white sugar.
  4. You can use the left over Cajun seasoning mix in the pan to make different batch of boiling seafood or just serve it as sauce on the side.
  5. If you decide to use larger size of seafood such as lobster, then it is best for you to cook them first.
  6. Cajun seasoning mix can be made separated to use for other recipes kept in an airtight container, in refrigerator, for up to 2 months.
  7. Per popular demand, I also added the volume measurement (tbsp and tsp) of each ingredients. However, I recommend to use the weight measurement whenever you can for more consistent flavor.
