Where I live the Angostura is hard to find, and extremely expensive. So this recipe sound like a real extravagance. But the ROI was good. At first sound like: take a full shot of Worcestershire sauce, but is not so strange the angostura in this amount. It taste well, since is with Mezcal is like a Naked and Angosto. Is a new totally different taste, very very spicy. I like it. Thank you Calvin Grant! for bring it to my attention.
