Start by washing all your fresh ingredients. Dice the cubanela peppers, crush the garlic cloves, and cut the red onion into strips. Chop the cilantro and set everything aside.
In a small bowl, combine the bija (annato) powder, oregano, and salt. Mixing these dry spices together will help distribute the flavors evenly when added to the sofrito.
In a large skillet, heat the olive oil over medium heat. Add the diced cubanela peppers and red onion. Sauté for about 3-5 minutes until the onions become translucent.
Next, add the crushed garlic and the mixed dry ingredients to the skillet. Stir well and cook for an additional 2-3 minutes until the garlic is fragrant.
Once the garlic is aromatic, add the chopped cilantro to the skillet. Stir everything together and cook for another minute. This will allow the flavors to meld beautifully.
Taste your sofrito and adjust the seasoning if necessary. You can add more salt or oregano according to your preference.
You can use the sofrito right away in your favorite dishes or store it in airtight containers for later use.
