I find pastrami roast to be a lot of fun, it’s a little bit different from the regular cuts I grew up with and it’s so flavorful (I often put one on top of my cholent. It’s unreal!) I bought this in Gourmet Glatt and they have stickers they put on meats educating you as to how best to make them. The sticker on their pastrami roast reads to add balsamic vinegar and brown sugar. I took their advice but added a bunch more ingredients to bring it up yet another notch.
