Place the flour, black pepper, sea salt, cayenne and dried oregano in a plastic bag and shake to mix well.
Add the chicken thighs, one at a time, and shake well so that they are coated all over. Lay the chicken thighs out on a plate.
Place 20 grams of the butter into the bowl of your multicooker and select the Fry > Vegetables option.
When the butter has melted add the onion and fry, stirring constantly with the stirring paddle for five minutes or so, until they begin to soften.
Remove the onions from the bowl of the multicooker and set aside.
Add the remaining 20 grams of butter and select the Fry > Meat option.
Fry the chicken thighs until browned on all sides, around 10 minutes.
Return the onions to the bowl of the multicooker, add 250 ml of chicken stock and the juice of one of the lemons.
Close the lid and leave until the end of the Fry > Meat cooking time (40 minutes cooking in total). Every now and again turn the chicken thighs so that they cook evenly. Alternatively, you could select STEW and slow cook the chicken thighs for 3-4 hours.
Meanwhile, rinse the rice until it runs clear and soak in enough cold water to cover.
At the end of the cooking time, remove the chicken thighs from the multicooker bowl and set aside for a moment.
Add the rice, the dehydrated vegetables and more chicken stock to the juices in the bowl - if you are using white rice you will need 350 ml of liquid in the bowl, if you are using wholegrain rice you will need 400 ml of liquid in the bowl.
Stir the rice and vegetables well, and then return the chicken thighs to the bowl, placing them on the top of the rice.
Place a thin lemon slice over the top of each chicken thigh.
Select COOK > 25 minutes for the white rice, or 35 minutes for the brown rice. Check at the end of the cooking time that the rice is cooked. If not, increase the cooking time by five minutes if needs be.
Serve directly from the removable multicooker bowl using the serving spoon which came with it.
