You’ll need sazón for the seasoning salt.
Here’s a recipe for one :
2 TBSP salt
2 tsp blk pepper
2 tsp garlic powder
2 tsp oregano
2 tsp turmeric
2 tsp onion powder
Blend together in a spice milk (aka your coffee grinder) or food processor.
Reduce the salt if too salty to you.
As for the sofrito, her’s is more on the Dominican side. Let me know if you want a recipe for the Puerto Rican version.
