It is. I've actually been swigging little sips of the bottled leftover juice all night nipping in for beers during our online dominos game
The only thing I strayed from the recipe was:
I only had dried chipotle chillis so I put everything for the spice mix in a pestle an mortal and ground it up.
I added a little bit of onion and a little bit of garlic powder each.
We pressure cooked - cut everything into matchbox size pieces, 30 minutes high pressure then fast release. You could actually shed it with one fork just stabbing at it.
Next time I wouldn't have used so much lime juice, it did give it that nice Mexican freshness but it was a bit overpowering at times. Not much but a little less.
My wife said she didn't notice but it also got her seal of approval - I've stopped asking her to rate my dinners out of 10 as it usually annoys me
but I have started to ask her if there's anything she would change about it - the only thing she could come up with was making something better to go with it instead of cheap fries, the beef was perfect.
I can't wait to have it tomorrow after it's soaked in the sauce overnight with some toasted sourdough bread and Philadelphia.
