Let's try, please let me know when you know at least half of this kind of tacos (the animal is beef unless otherwise specified) of your list. Maybe we can have an interesting conversation then:
1. Sesos (boiled brains). 2. Lengua (boiled tongue). 3. Tripas (deep fried pork intestine). 4. Moronga(fried pork blood). 5. Ojo (boiled eyeballs). 6. Higado (fried liver). 7. Tuetano(boiled bone marrow). 8. Cuerno (marrow, from the cow's horn). 9. Pepena (fried organ meat, mostly hearth, lungs and intestines). 10. Chicharron (fried porkskin).
If you don't think that's gross, I salute you and comend you for being a brave omnivorous. But most white people I know would not touch non-steak meat with a 10 foot pole if they could help it.
