Salt blends I love.

First of the spice blends I wanted to mention are some basic flavored salts (Sazon).   I use these frequently do I make a quick blends to save time from having to mix in small batches as needed for meals..

Simple salt and pepper:

Fill spice grinder 1/2 way with tellicherry black pepper berries and grind until powder

Mix with Himalayan pink sea salt fine ground
Great for basic meals that ask for Salt and Pepper.   Can be used as a table mix as well once balanced to your taste with pepper to salt ratios.

Szechuan salt and pepper:

Fill spice grinder 1/2 way with Szechuan pepper berries and grind until powder

Mix with Himalayan pink sea salt fine ground
Great for Stir Fry's or any meal that requires a bit of Szechuan flavor.  
 

Mixed peppers salt:

Fill spice grinder 1/2 way with a four corners blend (mix of white, black, pink, and green) and grind until powder 

Mix with Himalayan pink sea salt fine ground

Great for basic meals that ask for Salt and Pepper.   Can be used as a table mix as well once balanced to your taste with pepper to salt ratios.  I personally prefer this to just tellicherry black pepper berries due to the complexity of flavor.
 

Garlic and onion sea salt:

If you get onion and garlic flakes or even the scallions or dry the green tops of a scallion.  Fill up spice grinder and create a powder.  Not you can buy onion and garlic powder as well no need to grind. 

Mix with Himalayan pink sea salt fine ground
Great for mashed or roasted potatoes, vegetables, and even making a garlic bread from scratch.

Rosemary flavored sea salt:

Same as garlic and onion but add in dried rosemary. 
Great for mashed and roasted potatoes or fries.   Because rosemary can be a stronger flavor that does go well with potatoes in my opinion I primarily use this for my potato dishes as appropriate.

Spicy Grains of Paradise finishing salt:
Fill up spice grinder 1/2 way with the Grains of Paradise seeds and grind until powder.
Mix with Himalayan pink sea salt fine ground.
Great for a floral spicy note to food.  Use as a finishing salt to add another layer to African or middle eastern style meals.
