Place chicken or turkey parts, prunes, and turmeric at the bottom of a large slow cooker or crock pot.

Dice vegetables such as onions, carrots, potatoes, and turnip.

Fill the pot with the diced vegetables, ensuring they are no closer than 3 cm (1 inch) from the top.

Add cold water until the vegetables are covered.

Cook on high for 1 1/2 hours.

Reduce heat and cook on low for about 8 hours.

Just before serving, mix in the lemon juice.

Remove any bones before serving.
