    1. Actually Andy, the soy sauce and olive oil serves as the liquid in this recipe and it will come to pressure just fine based on our testing!

      1. It is easy to miss the 3/4 C of water in the ingredient list because of the included note. I missed it the first time I read it!

  1. I’ve made this twice, once in the slow cooker and it was fantastic, and now once in my stovetop pressure cooker, which was less than fantastic. I ended up with a pretty thick layer of burnt sauce on the bottom. It was still edible and pretty tasty, but nowhere near as good as the first time. Is there a reason that you don’t include cooking directions for stovetop pressure cookers? It would be nice for those of us still “kickin’ it old school” or who are waiting to bite the Instant Pot bullet?

    1. Hi Erin, Thanks for your feedback. I’m so sorry this recipe didn’t turn out for you. We find that the Instant Pot is the most widely used and popular and our own personal favorite. We have used others and all of our freezer cooking directions are written for any electric pressure cooker. I hope you’ll try another recipe with us. Since you’re using a stove top pressure cooker, I might suggest reducing the cook time a bit since it burnt on the bottom. Do you also have a trivet you can place inside your pressure cooker? We’ve found that to be helpful when having issues with burning to place the meat on a trivet to avoid direct contact with the Pressure cooker. You can place cookware in an electric pressure cooker, I am not sure if this is the same for stove top pressure cookers. ~ OAMM

  2. I got the burn error too with my IP. I had reduced the sugar because we don’t eat much, and thought that would help but it burned anyways. I took everything out, cleaned off the bottom, added a bit more water and it’s cooking at pressure now.

  3. I think those that failed missed the 3/4 C of water because of the note you included after carrots in the ingredient list! I missed it the first time I read it!

  4. I added the 3/4 cup but still it didn’t come to pressure and had a layer burnt on the bottom. I cleaned the pot and used pot in a pot method to finish. Mine was really thick in the suate part.

    1. We’re very sorry that you had trouble with this recipe, but we’re glad to hear that the pot-in-pot method worked well for you – that’s a great tip! Please let us know if we can help you further troubleshoot the problems you initially had 🙂
