Prepare the Annatto oil by heating up 1/2 cup of olive oil with 2 tablespoons of Annatto seeds in a pot and sautée them over low heat until the oil turns red. The seeds need to "crackle" a little.
Discard all the seeds of the peppers.
Cut all ingredients roughly and put them into the blender!
Blend thoroughly until puréed.
For later use, freeze the final product into ice cube trays. Then put the frozen cubes into plastic baggies.
