I am very excited to make this recipe but I’m wondering if I can use frozen cauliflower instead of fresh cauliflower? Is there any change that I will have to make if I choose fresh cauliflower?


That will work! I generally don't use it for making cauli-rice but it will work just as well as fresh for making cauli-mash 😊 No change needed although you may want to defrost before weighing and steaming.


If you were freezing this, could you reheat from frozen? If so would it be the same temperature just for longer? Thank you!


I would reheat in the oven on low - or defrosted. I think either will be fine as long as you keep the temperature low so it has time to heat through evenly.


We will definitely be making this hardy, delicious meal again. However, I will not be adding the xantham gum to the meat as it made it slimy.


You could use ground chia seeds OR my absolute favourite way to thicken sauces & gravies is by using egg yolks. Simply 1/2 cup chicken stock or bone broth + 4 egg yolks whisked together and slowly drizzled in the meat while stirring - until it thickens. Egg yolks really make the best gravies 😊
