Is this stew the same as pork posole?
Yes, they are essentially the same. Posole (aka”pozole”) is traditionally made with pork, but sometimes chicken is substituted. Posole always contains hominy, just like this recipe.
Do you want to cook this in your Instant Pot?
I’m a gadget person who likes things to happen fast. That’s why I’m in love with my Instant Pot(paid link).
Since I was raised on food cooked in a pressure cooker, it feels quite normal in a retro sort of way. However, my mom’s pressure cooker was a stove-top affair. Fortunately, I have no good explosion stories.
Does anybody besides me miss the sound of the happy “rocker?”
If you are new to this type of cooking, be warned that it takes longer than 7 minutes (the amount of time you set on the timer) to cook the soup. First, the pot must reach a certain pressure level before the timer kicks in. How much time this process adds depends on the temperature of the ingredients when you put the lid on.
How can I speed up the process when using an Instant Pot?
Heat all liquids before adding them to the Instant Pot when you need dinner on the table as fast as possible. Pop them into the microwave.
Also, avoid putting any frozen ingredients into your cooker. You don’t HAVE to do this, it’s just a shortcut for helping your Instant Pot get up to pressure faster. This will hasten the cooking of your food under full pressure.
Directions for making this Leftover Pork Roast Recipe on top of the stove:
Don’t feel left out if you don’t have a pressure cooker of some kind. First, follow step 1 using a large pot on top of the stove. Like step 2, add the remaining ingredients and simmer for 30-40 minutes.
You could also make this in a slow cooker and let it cook all day, but I would only do that if it’s convenient since long cooking is not really necessary.
FAQ about Leftover Pork Roast:
4-5 days. Wrap it well to keep it from drying out.
4-6 months is. Double-wrap it to prevent freezer burn.
Yes. I prefer to use the microwave, but the oven will work. Be sure the pork is covered (it may pop), and be careful not to let it dry out.
