The seeds are a gorgeous red and can be found in many Hispanic markets. I’ve also found it in Filipino grocery stores, as well. Almost all the Mexican stores I’ve visited carry it, too. It’s not very expensive, either. Of course you can shop for it online, for the easiest no-contact way to have it in your hands.
So, what is annatto used for?
Wow, so many uses in Puerto Rican cooking, and it’s great to experiment in other dishes, as well. You’ve probably heard of adobo– that rub you can make to add a Latin twist to many meats. The seeds are ground up with other herbs and spices and perhaps some oil then rubbed into meats before roasting , adding some amazing flavor. It’s also used to make an adobo seco, or dried spice mixture and that usually contains salt, garlic powder, ground annatto and an oregano that is a bit sharper than the traditional Italian variety (I get this at Mexican grocery stores).
Another way to use it is to color the cooking oil used to make rice. This gives the rice a deep orange color, or a darker hue than it already is (if using white rice). So, for an inexpensive alternative to saffron, works nicely.
The process of making the annatto oil is quite delicate, so the following instructions are in order- but they’re quite simple.
I probably don’t use as many annatto seeds as other cooks, but my method works for me. If you want to use more seeds, so be it. I think the oil portion of the cooking is much more crucial. Use good quality olive oil, but be very careful how it’s heated.
Continue this for 2-3 minutes, or until you begin to see any of the seeds turn a very dark red. That means that the seeds are beginning to burn and you should start to remove all of them as soon as possible.
You can strain the oil or use a spoon to remove the seeds.
My abuelita had a special little pan just for this, but that’s because she colored her oil for so many dishes on a daily basis.
I don’t really “taste” the flavored oil so much as I do smell the fragrance of the annatto, either. Of course you can still make the rice using plain olive oil, but this adds an amazing touch of authenticity to the plate.
