Tony,
I have tried the beans, but not pinquito style. I’ve only made it with pinto beans because they are readily available in NM. My parents by fresh picked beans close to there house from a place called Moriarity. The school mascot - Pintos...... hahaha.
But the beans were phenomenal. One of these days I’ll order some on the inter webs because I can’t find them here in my area. But, Santa Maria tri tip is one of my favorite recipes hands down. I love the flavor combination the beef has with the spices and sugar. Good eats!!!
