Bob Armstrong is having a moment today.

Well, in Austin, the former land commissioner and state representative is always having a moment because he’s always on the menu at Matt’s El Rancho, one of the most popular and iconic Tex-Mex restaurants in the city.

The Bob Armstrong dip, which Armstrong himself had been known to enjoy before his death in 2015, has the holy trinity of queso, guacamole and ground beef.

Lisa Fain, aka The Homesick Texan, recreated the recipe on her blog in 2014 — you’ll remember she has a whole queso book in the works — but last month, Bon Appetit published the official recipe from Bon Appetit’s Rick Martinez along with a video of how to put it together.
