Many people use a store-bought crab boil from brands like Old Bay and Zatarain's, but it's easy to make from spices you probably already have in your rack. Making your own crab boil seasoning means you can adjust the flavor to your tastes, too. If you like spicy food, add more red pepper flakes or toss in a few dashes of cayenne pepper.
For a crab boil, use 1/4 cup of the spice blend plus 1 part distilled white wine vinegar to 3 parts water. Add the seafood and cook for 10 to 15 minutes, or until the crabs float. Remove the crabs and serve or chill.
There’s little time involved to make your own low carb taco seasoning mix. And, you won’t be getting any unwanted sugar or starch in your own blend. Starch is added to thicken up the meat sauce when making tacos. However, that’s not essential and you can do the same thing if desired.
