Mix the two soy sauces and Worcester sauce in a freezer bag and prepare. Cut the meat and put in it, put the starch on top and knead everything really well. Becomes a little whitish. Let rest for about 30 minutes to 1 hour.
Slice everything else as indicated above.
Slow cooker:
Put the oil in the bottom of the pot. Put everything else on top (not the cream), including the meat and marinade, and stir. SC on high 2 hours and everything is done (couldn`t test low, mine has no LOW - just keep warm and that`s not enough.)
Roman pot:
First, water the pot, then add a little oil at the bottom and everything else, except for the cream, stir in and put in the cold oven at 120 degrees for 2 hours
On the stove:
Put everything except the cream in a large, heavy stew pot like in the slow cooker and stir well. Then cook on a very low flame, it should simmer just as easily, for 2 hours. Lift the lid as little as possible.
For all types of cooking:
If you want, you can stir in the cream shortly before serving and heat it again briefly. Season to taste with salt and pepper - done.
Everything that goes with sauce goes well with it.
